@@saulekaravirs6585 I prefer turbos over N/A for 4 wheels. I tend to squeeze the throttle too early which bites me in shifter karts (and has bitten my femur on my race bike) but in my cars it works out perfectly. I love the power application of my MR2. Never driven anything with a mechanically driven supercharger, so I don't have any comparison, but I'm assuming it would be similar to N/A. Now for 2 wheels, anything but N/A is blasphemy.
I thought you might be interested in knowing that your efforts in increasing the aviation community have been effective, at least in my little world. I started watching your stuff six months ago. In that time I have become totally captivated with the idea of building my own airplane. As a result of your site, I started to look at others and came across several build sites that deal especially in building with wood. Since then, I have ordered a kit that will be delivered in April. I have built a completely flat and true work table, and am in the process of selecting and putting a deposit on an engine. My plan is to start the build this coming year and in the summer begin flight lessons. Ideally, I should have my sport certificate when I have the airplane done. When I look back on it, none of this would have happened had I not stumbled on your Scrappy build.Thank you Mike, you are an inspiration!
I knew you wouldn't be satisfied with the Nitrous and i was expecting that you would replace the engine with a 1000hp turboprop....but twin turbo sounds really cool as well, as it means we can see the true potential of this monster engine.
@@cjhs77338 so much lighter for the same power that you can carry more fuel though, and reliable which with the best will in the world can't be said for a lyco... That's been heavily tuned.
I am amazed at the kindness Mike shows. It’s safe to assume he is making limited revenue from TH-cam ads, then decides to just send gifts out. He donates like crazy and volunteers for all forms of tasks. Thank you for being such a great role model mike. You make this world a better place!
Thinking back to my days flying KC-10s and found myself wondering: what about two sets of ailerons? Inboard and outboard. The extra set only unlocks at full flap settings. That’s a common setup on larger aircraft and seems easier than having one massive aileron and expecting it to perform the same across all flight profiles. But I’m no engineer! I’ll greatly enjoy watching the upcoming aileron development. Back to work!
Airliners do this too. They usually have a high and low speed set of ailerons. They also go one step further and start deploying spoilers when you get slow and need even more roll control.
@@martylawson1638 if I recall, on airliners, as the speed increases, ailerons are no longer used (or deflection is reduced or zero-ed) and the spoilers are used. At low speeds both the spoilers and ailerons are used.
The RC Draco is a great flying plane. My friend bought 6 of them and gave me one. I I hope Horizon is able to copy Scrappy. For all of us RC Nuts to enjoy.
That would be amazing (and ungodly expensive) if they were able to replicate those flaps. I work with a group of engineering students close by. Maybe we will have to try to put some of his work in the small scale.
In several very high-performance sailplanes, flaps and ailerons come down together, until a certain point… then the ailerons come back up to neutral or slightly negative as the flaps keep going down. This increases roll control immensely. Maybe your last foot of aileron could do the same? Something to ponder, I think.
Many high performance RC saileplanes do the same. I'm afraid that this is the only way. You will probably have the same negativ effect with increased ailerons.
You are the most awesome engineer/designer in all aviation, Mike! I just am so sorry I'll never get to meet you. As a pensioner in Australia, many things are beyond my budget reach, but I simply adore everything you do! Oh, and I miss Draco! It would be awesome if you could get one of the plastic modelmaking companies to do a 1/48 scale plastic kit of the almighty Draco!
I know the issue with the Ailerons. I had the same issue with my Own-design homebuilt. Its nowhere near as hard core as Scrappy, but it has a wing with really nice low-speed characteristics. It was getting airborne well before full aileron effectiveness, so was tricky in crosswinds! In my case, a row of vortex generators on the leading edge in front of the ailerons sorted the issue pretty easily. making improvements down the track is absolutely normal for own-designs!
It would be so easy to say “its perfect” but that’s not you and that’s why we love you Mike! You are totally honest and we love that! I absolutely love the fact you are designing your own prop hub. If anyone else told me that I would say they are nuts 😂
I knew Scrappy was going to be a "work in progress". Mike is always innovating and improving. Loved the initial build series, and the upgrades and improvements are going to be awesome 👍
I don't know if anyone but me will remember me joking about Scrappy being able to hover and take of like a VTOL craft when the prop was revealed - but I think reverse so Scrappy can back in like Draco would honestly be cooler. I also think the turbo plan is far smarter long term than the nitrous, especially with the altitudes Scrappy will be taking off at. And after seeing those DA figures, the electric bikes really make even more sense. Overall, nice job.
Love these videos!! What about adding Vg's on the wings outboard area that would stop span wise flow and send some more air over the ailerons at lower speed? Your engineering from start to finish on this project is mind blowing! Hopefully I will see this flying over Lehi on the weekends. Keep up the great work... Back to work!!
I expect extending the ailerons would increase low-speed roll-control authority, but it seems a shame to change what works well at higher speed. I have a couple of alternate ideas. One is a flap-like extension of the ailerons that automatically deploys at airspeeds below 40 knots. That's still a weight penalty. Another is a flaperon modification of the flaps and slats that differentially changes the slat and flap extension in concert with the ailerons at low speed. (While relatively simple conceptually and mechanically, this requires replacing the flap motor with two servo motors and a control law computer system. I don't like the possibility of increased stall speed for the "down" wing.) My favorite idea is to use a pair of electrically driven tilting propellors tied to the ailerons. They could either be mounted on the wingtips similar to the V-22 tilt-rotor configuration, or attached directly to the ailerons in a pusher configuration to apply thrust with a vertical component equal to the aileron angle. At speeds above 40 knots, the blades would be feathered and angled parallel to the wings. To get more use out of this setup, speed control for the motors would have an input from the rudder pedals to augment low-speed yaw control. (I suppose a pusher configuration would be preferable for wing-tip motors as well since that would be less likely to perturb airflow over the wings and possibly cause unwanted separation.) I enjoyed this video and its predecessors; they're intellectually stimulating as well as entertaining. Thanks!
Missed your updates. Glad to see a video now and then gets me more and more motivated. Would love to hear/ see something about how you met garret/cleetus Both of you do so much to give back to the communities you are apart of.
Can't wait to see how many "Scrappy" features there will be utilized on Draco-X when or if it gets built! I'm quite sure that if Draco had had the adjustable undercarriage, it wouldn't or probably wouldn't be lying as a scrap heap. Saying that Scrappy is the most fabulous and innovative plane I've ever seen. Burt Rutan has got some stiff competition here!
I keep wondering if he'll bolt extra electric engines under the wings where we expect to see electric bikes and test what that does.... Or something like a C130 rocket assisted short take off....
Awesome update. Love how slow and level Scrappy flies. Hopefully the larger ailerons are enough. But there's still the option of roll control spoilers, or mixing the ailerons into the split-flaps...
I just discovered this channel yesterday. Watching the crazy custom talks about Scrappy has been eye-poppingly cool! YES, that was my thought too, spoilerons! It seems like a good candidate, as all the big jets do it. I sat thinking, well, you've succeeded in creating a wing with such enormous lift capability that you run out of roll control before the thing will stall…so, kill some of that lift on the high-wing. Good idea. I've read a few sources that suggest wings are typically designed to stall at the root first, so roll control is the last thing to be lost as a stall develops. Another consideration for the flight-test program: what's the effect of the rudder on roll in slow flight and high AoA situations. This wing is unique in that slow flight might not necessarily equate to a high AoA situation. But various sources I've encountered tell me that in typical aircraft, and especially the big jets, when you've got high AoA on and you're near the stall, the rudder becomes a primary roll-control device. Then of course, when near stall, trying to pick up the low wing with aileron may push that side into stall, and suddenly the stick seems to do the opposite of what you intended! The guidance is to keep the ailerons neutral and roll with rudder. A complication for the spoileron idea: you might want the spoileron to activate only during special parts of the flight envelope, not be something that comes up every time the stick moves to the side. So, plenty of variables to sort thru in design and fluid simulations.
Mike, you have been part of the inspiration that re-lit the fire under my ass to pursue my lifelong passion for aviation. I am taking my PPL check ride tomorrow, and have already passed my instrument written. I also finally got my Scrappy wing spar kit a few days ago! I've been showing it off to everyone. THANK YOU for your contagious passion and inspiration!
For the roll control - in RWD-9, in 1933 the constructors made interceptors activated mechanically when l.e. slats were opened. They needed it for low-speed trial in Challenge 1934. At first it was 100x8 cm in size, but the aircraft was drastically too sensitive and the proper size appeared to be 25x4 cm. By the way, the pilot did not control the wing except for ailerons, slats were sucked out at low speeds and by mechanical connection they were extending the flaps. Plus this interceptor activation. Ah, and drooping ailerons were there too.
You and your team are an inspiration to us all! Everytime I watch your videos I think, "This is what TH-cam is all about!" You keep pushing me into signing up for that first flight. A few times over the last 20 odd years I backed off due to family priorities. Maybe, just maybe it's time! R/C only gets me so far! Thanks for all you do!
I wonder if that is power off or power on. Full flaps and adding full power in a 152 requires a kot of pushing the nose down untill you can dump the flaps. But then Mike didn't design a C 152.🤔
"I can't believe how slow it flies" exactly my first thought that first time I saw you land Scrappy. That shot of Scrappy "on station" against the wind blew my mind with the possabilities of "search and rescue". Yes "air flow design" is pure genious, the human mind + the power of computing! Thank you Mike. Kind regards, Malcolm, Australia.
Your spindle is still hollow! Water/dust/crud can travel down the inside of your spindle into your wheel bearings! Love your work! Thanks for the update!
Please come out with more flying videos. The videos from building your planes are always freaking amazing, but after so much "invested" time in building "with you" it would be amazing with some more flying videos. Cockpit FPV of you taking off / landing at different places, time to altitude, stall testing etc etc.
Like so many, I am in awe of you, your brother’s, your wife’s and your sons’ intellect, passion, and drive. Thank you so much. (I bend aluminum on a B-17G and am guided by drawings made 80 years ago.). I am grateful to be guided by engineers from decades past. I think the richest evening imaginable would be you, Orville, and Wilbur in the same room for about three and a half hours…
Your ear to ear grin is on your face 24/7. Not just when you fly. Obviously few of us here can see that, but it's apparent. It's your signature and it's very admirable.
Love the whole project and your craftsmanship. All I want for Christmas is more videos of the build and the test flights. If you have the video, can't you delegate someone to edit it and post it?
Greetings from South Africa. Love the new plans Mike, it's going to be awesome. I still feel there is such a big gap in your video's as you finished the plane off, would love a video on attaching the wings, finishing touches etc, and first flights. I know you were under pressure to get to Oshkosh, but if you have that footage, would love to see it. Can't wait for all your videos !!
I can only imagine how much engineering is going into building your own prop mechanism. If there's anyone who can DIY that, it's you. Absolutely crazy capabilities you've built up and I just love seeing you make such great use of all your skills.
It is so thrilling to see Scrappy fly and the changes you will be making. Having watched this aircraft from its infancy to today has been a wonderful journey. Thanks, Mike.
The referencing of Wheelie and the Chopper Bunch was great! I look forward to seeing these changes happen. Once again we'll get to see an already amazing aircraft get some major improvements. Thanks as always for bringing us along with you Mike and family.
I am looking forward to some future where we get to see some big epic Alaska adventures. I hope to see a moose,sheep or cooler of salmon on a dirt bike mount at some point! Love that wing design!
At 75, I am a disabled Vietnam Vet. I live near the Nut Tree airport in Vacaville, CA. North of Travis AFB. If you are ever in the neighborhood, I would love to visit Scrappy!!
Wow Mike I simply can not believe that you took a crashed cub and turned it into arguably the best, most complex and versatile STOL aircraft in the world. You have been a huge inspiration for me and you never cease to amaze me with you incredible aeronautical marvels. I would love to see the turbos on scrappy and cannot wait to see its peak performance. Keep up the incredible work and whats more could you please shed a little more light on Draco x. Thank you so much for you time.
You have been a huge motivation for me to get in the air. Got an old piper tri-pacer air tractor this summer and am a week or so away from my solo flight. Thank you! I am a Marine Corps combat vet who struggles with ptsd and huge disappointment and anger at our world these days. Flying seems to take all that away and I'm able to have mental peace while flying even in the rough weather. Hope to fly my old bird to Oshkosh this next go around to hangout with all the uplifting pilots. Once again thank you for all you do. I better get back to work. Merry Christmas from my family to yours.
Thanks for your channel giving me so much enjoyment. I also got your SCRAPPY spar as a gift from my daughter and son in law proudly displayed in my living room. Always looking forward to your next video. Merry Christmas to you and all the Patey's
I stumbled across this video (I’m a helicopter pilot) and barely 5 mins in I’d like to say “what a guy” - really lovely bloke, family man, infectious enthusiasm/smile, clearly a great pilot and incredible engineer….incredibly creative too - now back to the video! 😉😎
Mike Patey, love you and love your videos! You have inspired me to chase my childhood dreams of flying that I had previously given up on. I am 47 and determined to get my pilot’s license within the next two years. Hope to see Scrapy in Valdez Alaska at our fly in!!!
👍Was just thinking about you today. Thought you're likely taking a break from work since it's the holidays coming up. Yet that only means you're busy working. Understand completely about giving steadfast numbers. Everything is relative. I've never been a fan of but intermittent power of nitrous plus when the bottle's gone so is the power. Can't wait to see the constant speed unit for that propeller. That will be one more nice addition to Aviation. Thanks again Mike stay safe and enjoy after all life is what we make of it. 🤠🐂🏞️🛩️
In my knowledge range of aeroplanes, which is zero, it sounds more like it needs a flap on the wing tips. Max leverage. Or, falls right behind the prop, so when you pull the loud lever you have most surface control, but in a local area. *anyhoo, bloody chuffed you built the aeroplane of your dreams :D
It would never let me finish my Scrappy spar order, but I will try again right after this video. Just to have a peace of my favorite bush-plane would be amazing.
I am to bad with health to be in what you guys do But I TRULY love the channel because of your excitment of what you do. And how you love your fans. Merry Christmas to all your family and friends. To the people that are not talked about much is the camera man -woman thank you for outstanding videos I know it takes a lot to film and make it work. THANKS
for the propeller control.. are you going to put a spur gear around the hub with a bolt on second gear housing to complete the pump.. allowing you to easily inspect the drive gear sides and the complete driven gear by just unbolting the cover.. the oil around the hub where the main drive gear is also cools the hub and housing. oversizing the case opening for the driven gear housing could allow you to machine a larger driven gear or a smaller driven gear and housing if the oil flow is not correct .. without redesigning the main housing. shims to change gear clearance between the drive and driven gear.. bearings.. double row ball bearing up front.. self aligning roller bearing on the rear (barrel shaped roller) as that will probably handle the side loads better as are exerted by the prop and which ever drive you have..
Future Mike: Well I didn't like how she was flying below 12 miles per hour, so I added vortex generators on pneumatic pogo sticks out the end of the wing to channel airflow into the slip stream, and help the ailerons gain authority. But I wasn't happy with it, so since I had this huge solar array, I got several ducted fans for RC Jets and mounted them in place of the vortex generators, so now when I lose roll authority I hit the button a few times and blast them with air and we are back in control!
my real flying kind of ended that summer when i had my first solo flight. that was when i was 16. 34 now with 15 years of aircraft maintenance experience and on flight sims since mfs95, back in rc planes for last few years (since high school), and i noticed a thing about alerons. had this lovely foam corsair, 1.1m span. loved to hover on strong winter winds with it... but, i wanted to go slower. i dug in to rx and tx manuals and found out i can programme ail droop with flaps. so i did. it sure brought stall speed down, but it more than halfed the roll authority. i think that in droop mode, the up aileron should travel allmost the same ammount as not drooped one, where my tx progamming only eased it off about 70-80% towards neutral. i see scrappy is behaving in a similar manner. just a thought... ps. because of You Mike, im thinkin of ppl again. Thanks
Merry Christmas to the Patey family and we your-“best” fans are looking forward to some new videos in 2022 if possible, enjoy and have a very merry Christmas…
For low speed "aileron" control, maybe consider secondary spoilers in the prop wash area (flaps?) aka the MU-2. Or having individual control on the flaps themselves. Or if you want to cheat, embed some bidirectional drone like motors near the wing tips. If you had speed sensing you could proportionally mix them with aileron input, and above a certain speed have lovers shut over them. Larger ailerons alone are only going to take you a little bit slower without really reducing susceptibility to gusts. You need airflow, either existing ( in the prop wash area) or what you induce (aka drone motors). The reality you are the same place the X-15 was. Just not enough molecules of air passing over the ailerons to work with. Their solution was a reaction control system. Glad to hear you are going to a constant speed prop
Patey ! Great to get an update on You and Scrappy. I guess You had to get the slide rule back out to design/create Your Engineering Changes. I am interested to see your engine updates. Lots of variables changing on the wing and power plant, not to mention the prop. Sounds like another patent or 3 coming up.
Forgive me for this Mike. After seeing the RC Draco, and noticing a little man inside the cockpit. I thought I need to go to your website and zoom in on the little guy. I was excited to see if he looks like you in the RC plane. After zooming in, I thought wait a minute, that little guy has a full head of hair… Mike, you are a true inspiration. After working on my pilot license for some years now, you make me really want to fulfill my dream. One day, I will be finished with my private license. One day, I will meet you in person and shake your hand. You are a legend. Please keep inspiring so many people in this amazing industry. Thank you.
With the massive battery capacity Scrappy has a variable speed electric motor direct drive positive displacement supercharger would be a lot less plumbing with no waste gate and the complexity that comes with a dual turbo charger setup. Probably quite a bit lighter also when you look at the plumbing dual intercoolers and fuel management complexity. With the aero drag Scrappy has you probably want the power mainly for takeoff and climb, so time wise maybe 5 minutes max. With a VS superchager, just set the manifold pressure you want, set the fuel flow and you are good to go. Also lots of big PD superchargers out there to choose from that will supply all the air you want in that big motor. Separate independent oil system, a single intercooler and very little plumbing. Might be worth considering.
I was doing work when I got this alert. Gotta have my priorities. 😆😆 Merry Christmas Mike. I wish you and your family nothing but the best. Thanks SO much for sharing your life, your passion and your love of all things aviation! P.S. Scrappy is on my tree this year!!!
Just wanted to thank you from afar. I grew up around airports and GA as my dad flew cubs and huskies for a living. Spent summers in hangars helping our local A&P repaint planes. Read every aviation book in the house and our library but circumstances and other aspirations kept me from learning how to fly. Your content has really helped to "re" spark my interest in aviation. Finally kind of have the means to pursue at the young age of 54. Picked up a 150 a couple of months ago and am now taking lessons (a whole whopping 5 hours at this point...lol). Keep the content coming. Just your vids alone are sparking interest out there. Now If I could figure how to fit my Pivot MTB in the back of the 150, I'd be set :). Great stuff. Keep it up.
Wish My Grandfather was around to see your videos. He gave me my first plane ride, in Arrow II. His first plane ride was a B25, to chill beer over the pacific. for him it wasn't about the beer, it was the ride. one of the engines caught fire. thankfully he didn't have to bail out, because he grabbed the wrong pack, and not a parachute.
I hit the thumbs up before I watch ur video.....sowing (giving back) to the community is a key that unlocks incredible reaping (blessing) and is a spiritual principle that works beyond measure. You have demonstrated this time and again Mike. Thank you for sharing.
Thank you so much for the amazing gift guys!!!! Love the scrappy spars and the extra goodies . Merry Christmas everyone and all the best in the new year
Hope you don’t mind me offering this thought. Instead of extending the aileron, is there a way to take a bleed from any of these; engine or prop wash or electric compressor and blowing it over existing aileron at low speeds only?Kind of reverse of the Formula 1 blown defuser.
I need to rewatch the wing build but I recall there is access and space. Having watched these videos for sometime I would never rule out work or difficulty as a reason for not proceeding with an elegant engineering solution. Having said that I think there are some options to do something at the aileron if you have enough information about what angle of attack you start to lose flow.
I can’t wait to hear and see scrappy with twin turbos. This plane keeps getting more and more insane. It’s only a matter of time before you add a JATO function. I was also wondering if you thought of some sort of spoiler on system to help with some extra roll control.
I made a bet long ago that twin snails would be the route you went. Guess I can collect on that one 😀 Awesome video as always, and love what you are doing for others!!!!!!!
Nice ! Mike Happy Holidays to you and the family... Great new video and all your videos, 6.3 likes and no dislikes amazing Got one question and do wonder if you had both airplanes how would you use them for different backcountry outings?
The F14 used differential horizontal stabilizers to control roll. With that big prop pushing the air (and the need for rear ballast when you add that CS prop anyway) maybe you could look into engineering something like that to help your ailerons out?
A couple too many great ideas tried all at once. My greatest wish is you allow (or design) a Partey Twin Wing for RV aircraft. Longer, thinner, and able to land 15 knots slower while increasing miles per gallon at cruise and top speed to a degree that seems incredible
Mike Patey you sent my son a ornament and stickers and I can testify that you do give BACK to aviation. Jason just wants us to pay it forward pray for us please sir I’m trying to get my A&P but I worry every day about paying for it. Thanks so much for your gift I cried my eyes out because I couldn’t really even afford it but because your group is so kind he still got this amazing gift. You always say if you can make a difference in 1 person your good..... Back To Work
Haha, called it! Not just one aspect, but two...constant speed prop with beta, and inadequate ailerons. Flying that slow with stock ailerons and then making them droop, it's like a negative feedback loop where you can't get slow enough to really utilize the flaperons because you lose aileron effectiveness as a result. I was half expecting the turbos too, but was hoping to see the nitrous work with a constant speed prop first.
I went to your shop and the Draco ornaments are already sold out! That's amazing! A great update and thank you for being so honest about the positives and negatives you've experienced with Scrappy. Now, how about an RC Scrappy....
Let's be honest, I don't think any of us believed you would be satisfied with the occasional burst of nitrous 😄 Can't wait for project turbo!

You’re a generous guy, Mike. Thanks for supporting and building the aviation community!
Thinking back to my days flying KC-10s and found myself wondering: what about two sets of ailerons? Inboard and outboard. The extra set only unlocks at full flap settings. That’s a common setup on larger aircraft and seems easier than having one massive aileron and expecting it to perform the same across all flight profiles. But I’m no engineer! I’ll greatly enjoy watching the upcoming aileron development. Back to work!
Airliners do this too. They usually have a high and low speed set of ailerons. They also go one step further and start deploying spoilers when you get slow and need even more roll control.
@@martylawson1638 if I recall, on airliners, as the speed increases, ailerons are no longer used (or deflection is reduced or zero-ed) and the spoilers are used. At low speeds both the spoilers and ailerons are used.
MU-2: **stares with confusion** What are ailerons?
Stabilators controlled independently. Ailerons are for high speed, differential Stab for slow speed. Works famously on jets that fly 0-700 Kts.
@@ACSFlyingfish it's the other way around. Differential spoilers come in at lower speeds.

I need to be friends with your friend.
In several very high-performance sailplanes, flaps and ailerons come down together, until a certain point… then the ailerons come back up to neutral or slightly negative as the flaps keep going down. This increases roll control immensely. Maybe your last foot of aileron could do the same? Something to ponder, I think.
Many high performance RC saileplanes do the same. I'm afraid that this is the only way. You will probably have the same negativ effect with increased ailerons.
You are the most awesome engineer/designer in all aviation, Mike! I just am so sorry I'll never get to meet you. As a pensioner in Australia, many things are beyond my budget reach, but I simply adore everything you do! Oh, and I miss Draco! It would be awesome if you could get one of the plastic modelmaking companies to do a 1/48 scale plastic kit of the almighty Draco!
Thanks for all that you do for aviation! And by the way I love my Best Tug! Thanks to you and your family for signing it! Steve F.
I know the issue with the Ailerons. I had the same issue with my Own-design homebuilt. Its nowhere near as hard core as Scrappy, but it has a wing with really nice low-speed characteristics. It was getting airborne well before full aileron effectiveness, so was tricky in crosswinds! In my case, a row of vortex generators on the leading edge in front of the ailerons sorted the issue pretty easily. making improvements down the track is absolutely normal for own-designs!
Haven't even watched the video yet, and im already grinning from ear to ear. Love this guy. Love his videos.
Same here Scott ,👍 soon as I got notification . Take Care and Merry Christmas 🎄☃️
When Mike said he wanted to make a constant speed prop I didn’t know he was going to keep those awesome blades. 👍
It would be so easy to say “its perfect” but that’s not you and that’s why we love you Mike! You are totally honest and we love that!
I absolutely love the fact you are designing your own prop hub. If anyone else told me that I would say they are nuts 😂
I live in Karachi Pakistan I like your comments send 4 month ago
This project is so cool. Time to watch another Scrappy Update!
I knew Scrappy was going to be a "work in progress". Mike is always innovating and improving. Loved the initial build series, and the upgrades and improvements are going to be awesome 👍
Love the bikes. Can't wait to see the constant speed unit for the prop. That'll be one more leap for Aviation.
I don't know if anyone but me will remember me joking about Scrappy being able to hover and take of like a VTOL craft when the prop was revealed - but I think reverse so Scrappy can back in like Draco would honestly be cooler. I also think the turbo plan is far smarter long term than the nitrous, especially with the altitudes Scrappy will be taking off at. And after seeing those DA figures, the electric bikes really make even more sense.
Overall, nice job.
Love these videos!! What about adding Vg's on the wings outboard area that would stop span wise flow and send some more air over the ailerons at lower speed? Your engineering from start to finish on this project is mind blowing! Hopefully I will see this flying over Lehi on the weekends. Keep up the great work... Back to work!!
The excitement I get from seeing a Mike Patey video is like the first time, every time.
I expect extending the ailerons would increase low-speed roll-control authority, but it seems a shame to change what works well at higher speed. I have a couple of alternate ideas. One is a flap-like extension of the ailerons that automatically deploys at airspeeds below 40 knots. That's still a weight penalty.
Another is a flaperon modification of the flaps and slats that differentially changes the slat and flap extension in concert with the ailerons at low speed. (While relatively simple conceptually and mechanically, this requires replacing the flap motor with two servo motors and a control law computer system. I don't like the possibility of increased stall speed for the "down" wing.)
My favorite idea is to use a pair of electrically driven tilting propellors tied to the ailerons. They could either be mounted on the wingtips similar to the V-22 tilt-rotor configuration, or attached directly to the ailerons in a pusher configuration to apply thrust with a vertical component equal to the aileron angle. At speeds above 40 knots, the blades would be feathered and angled parallel to the wings. To get more use out of this setup, speed control for the motors would have an input from the rudder pedals to augment low-speed yaw control. (I suppose a pusher configuration would be preferable for wing-tip motors as well since that would be less likely to perturb airflow over the wings and possibly cause unwanted separation.)
I enjoyed this video and its predecessors; they're intellectually stimulating as well as entertaining. Thanks!
Missed your updates. Glad to see a video now and then gets me more and more motivated.
Would love to hear/ see something about how you met garret/cleetus
Both of you do so much to give back to the communities you are apart of.
Can't wait to see how many "Scrappy" features there will be utilized on Draco-X when or if it gets built! I'm quite sure that if Draco had had the adjustable undercarriage, it wouldn't or probably wouldn't be lying as a scrap heap. Saying that Scrappy is the most fabulous and innovative plane I've ever seen. Burt Rutan has got some stiff competition here!
I keep wondering if he'll bolt extra electric engines under the wings where we expect to see electric bikes and test what that does....
Or something like a C130 rocket assisted short take off....
Awesome update. Love how slow and level Scrappy flies. Hopefully the larger ailerons are enough. But there's still the option of roll control spoilers, or mixing the ailerons into the split-flaps...
I just discovered this channel yesterday. Watching the crazy custom talks about Scrappy has been eye-poppingly cool! YES, that was my thought too, spoilerons! It seems like a good candidate, as all the big jets do it. I sat thinking, well, you've succeeded in creating a wing with such enormous lift capability that you run out of roll control before the thing will stall…so, kill some of that lift on the high-wing. Good idea. I've read a few sources that suggest wings are typically designed to stall at the root first, so roll control is the last thing to be lost as a stall develops.
Another consideration for the flight-test program: what's the effect of the rudder on roll in slow flight and high AoA situations. This wing is unique in that slow flight might not necessarily equate to a high AoA situation. But various sources I've encountered tell me that in typical aircraft, and especially the big jets, when you've got high AoA on and you're near the stall, the rudder becomes a primary roll-control device.
Then of course, when near stall, trying to pick up the low wing with aileron may push that side into stall, and suddenly the stick seems to do the opposite of what you intended! The guidance is to keep the ailerons neutral and roll with rudder.
A complication for the spoileron idea: you might want the spoileron to activate only during special parts of the flight envelope, not be something that comes up every time the stick moves to the side. So, plenty of variables to sort thru in design and fluid simulations.
Merry Christmas to all of you and your Families. God Bless 🎆 🎄
Mike, you have been part of the inspiration that re-lit the fire under my ass to pursue my lifelong passion for aviation. I am taking my PPL check ride tomorrow, and have already passed my instrument written. I also finally got my Scrappy wing spar kit a few days ago! I've been showing it off to everyone. THANK YOU for your contagious passion and inspiration!
Merry Christmas to you and your family and the entire Patey clan. Thanks for your aviation awesomeness!
How does this vlog only have 269,000 subscribers??? Spread the word! I wish I was new to the channel, and got to binge watch the past videos!
For the roll control - in RWD-9, in 1933 the constructors made interceptors activated mechanically when l.e. slats were opened. They needed it for low-speed trial in Challenge 1934. At first it was 100x8 cm in size, but the aircraft was drastically too sensitive and the proper size appeared to be 25x4 cm.
By the way, the pilot did not control the wing except for ailerons, slats were sucked out at low speeds and by mechanical connection they were extending the flaps. Plus this interceptor activation. Ah, and drooping ailerons were there too.
You and your team are an inspiration to us all! Everytime I watch your videos I think, "This is what TH-cam is all about!" You keep pushing me into signing up for that first flight. A few times over the last 20 odd years I backed off due to family priorities. Maybe, just maybe it's time! R/C only gets me so far! Thanks for all you do!
NO stick pressure change when deploying all the trick stuff, that right there is amazing!
Perfect engineering equaled perfect balance.
I wonder if that is power off or power on. Full flaps and adding full power in a 152 requires a kot of pushing the nose down untill you can dump the flaps. But then Mike didn't design a C 152.🤔
"I can't believe how slow it flies" exactly my first thought that first time I saw you land Scrappy. That shot of Scrappy "on station" against the wind blew my mind with the possabilities of "search and rescue". Yes "air flow design" is pure genious, the human mind + the power of computing! Thank you Mike. Kind regards, Malcolm, Australia.
My Phantom ultralight lands at 35mph LOL!
Your spindle is still hollow! Water/dust/crud can travel down the inside of your spindle into your wheel bearings! Love your work! Thanks for the update!
Please come out with more flying videos. The videos from building your planes are always freaking amazing, but after so much "invested" time in building "with you" it would be amazing with some more flying videos. Cockpit FPV of you taking off / landing at different places, time to altitude, stall testing etc etc.
Oh man! Made my evening to get back in touch! Merry Christmas everyone!
I have my ppl checkride on the 15th of January, thank you for the inspiring content and awesome engineering.
Like so many, I am in awe of you, your brother’s, your wife’s and your sons’ intellect, passion, and drive. Thank you so much. (I bend aluminum on a B-17G and am guided by drawings made 80 years ago.). I am grateful to be guided by engineers from decades past.
I think the richest evening imaginable would be you, Orville, and Wilbur in the same room for about three and a half hours…
Your ear to ear grin is on your face 24/7. Not just when you fly. Obviously few of us here can see that, but it's apparent. It's your signature and it's very admirable.
This is badass!!!
I just recieved my Scrappy Spars just in time for Christmas they are so cool ,they are the perfect completion to my desk ! Thanks Mike !
Love the whole project and your craftsmanship. All I want for Christmas is more videos of the build and the test flights. If you have the video, can't you delegate someone to edit it and post it?
Greetings from South Africa. Love the new plans Mike, it's going to be awesome. I still feel there is such a big gap in your video's as you finished the plane off, would love a video on attaching the wings, finishing touches etc, and first flights. I know you were under pressure to get to Oshkosh, but if you have that footage, would love to see it. Can't wait for all your videos !!
I can only imagine how much engineering is going into building your own prop mechanism. If there's anyone who can DIY that, it's you. Absolutely crazy capabilities you've built up and I just love seeing you make such great use of all your skills.
Yay!
It is so thrilling to see Scrappy fly and the changes you will be making. Having watched this aircraft from its infancy to today has been a wonderful journey. Thanks, Mike.
The referencing of Wheelie and the Chopper Bunch was great! I look forward to seeing these changes happen. Once again we'll get to see an already amazing aircraft get some major improvements. Thanks as always for bringing us along with you Mike and family.
Mike, your charity towards the aviation community is awesome! You deserve a medal pal.
I am looking forward to some future where we get to see some big epic Alaska adventures. I hope to see a moose,sheep or cooler of salmon on a dirt bike mount at some point! Love that wing design!
At 75, I am a disabled Vietnam Vet. I live near the Nut Tree airport in Vacaville, CA. North of Travis AFB. If you are ever in the neighborhood, I would love to visit Scrappy!!
Wow Mike I simply can not believe that you took a crashed cub and turned it into arguably the best, most complex and versatile STOL aircraft in the world. You have been a huge inspiration for me and you never cease to amaze me with you incredible aeronautical marvels. I would love to see the turbos on scrappy and cannot wait to see its peak performance. Keep up the incredible work and whats more could you please shed a little more light on Draco x. Thank you so much for you time.
You have been a huge motivation for me to get in the air. Got an old piper tri-pacer air tractor this summer and am a week or so away from my solo flight. Thank you! I am a Marine Corps combat vet who struggles with ptsd and huge disappointment and anger at our world these days. Flying seems to take all that away and I'm able to have mental peace while flying even in the rough weather. Hope to fly my old bird to Oshkosh this next go around to hangout with all the uplifting pilots. Once again thank you for all you do. I better get back to work. Merry Christmas from my family to yours.
Semper FI my brother.
Thank you for your service.
1980-86 USMC.
Take care,
Be safe.
@@deanmiles3505 thank you as well brother Semper Fidelis for sure!
So much fun you had designing and building those wings. Congrats.
Loved seeing your cameo with Cleetus. Also, a collab with Xyla Foxlin would be amazing.
Thanks for your channel giving me so much enjoyment. I also got your SCRAPPY spar as a gift from my daughter and son in law proudly displayed in my living room. Always looking forward to your next video.
Merry Christmas to you and all the Patey's
I stumbled across this video (I’m a helicopter pilot) and barely 5 mins in I’d like to say “what a guy” - really lovely bloke, family man, infectious enthusiasm/smile, clearly a great pilot and incredible engineer….incredibly creative too - now back to the video! 😉😎
Mike Patey, love you and love your videos! You have inspired me to chase my childhood dreams of flying that I had previously given up on. I am 47 and determined to get my pilot’s license within the next two years. Hope to see Scrapy in Valdez Alaska at our fly in!!!
Got my ornament hanging on the tree already! Couldn't order fast enough when I got the email!
May You & all your family, have a Safe & Joyous Holiday Season!
👍Was just thinking about you today. Thought you're likely taking a break from work since it's the holidays coming up. Yet that only means you're busy working.
Understand completely about giving steadfast numbers. Everything is relative. I've never been a fan of but intermittent power of nitrous plus when the bottle's gone so is the power. Can't wait to see the constant speed unit for that propeller. That will be one more nice addition to Aviation. Thanks again Mike stay safe and enjoy after all life is what we make of it.
🤠🐂🏞️🛩️
In my knowledge range of aeroplanes, which is zero, it sounds more like it needs a flap on the wing tips. Max leverage. Or, falls right behind the prop, so when you pull the loud lever you have most surface control, but in a local area. *anyhoo, bloody chuffed you built the aeroplane of your dreams :D
It would never let me finish my Scrappy spar order, but I will try again right after this video. Just to have a peace of my favorite bush-plane would be amazing.
I am to bad with health to be in what you guys do But I TRULY love the channel because of your excitment of what you do. And how you love your fans. Merry Christmas to all your family and friends. To the people that are not talked about much is the camera man -woman thank you for outstanding videos I know it takes a lot to film and make it work. THANKS
for the propeller control.. are you going to put a spur gear around the hub with a bolt on second gear housing to complete the pump.. allowing you to easily inspect the drive gear sides and the complete driven gear by just unbolting the cover.. the oil around the hub where the main drive gear is also cools the hub and housing. oversizing the case opening for the driven gear housing could allow you to machine a larger driven gear or a smaller driven gear and housing if the oil flow is not correct .. without redesigning the main housing. shims to change gear clearance between the drive and driven gear.. bearings.. double row ball bearing up front.. self aligning roller bearing on the rear (barrel shaped roller) as that will probably handle the side loads better as are exerted by the prop and which ever drive you have..
Mike have a Happy Christmas for you and your family and I really look forward to the New Year improvements on Scrappy! Fly Safe!
Future Mike: Well I didn't like how she was flying below 12 miles per hour, so I added vortex generators on pneumatic pogo sticks out the end of the wing to channel airflow into the slip stream, and help the ailerons gain authority.
But I wasn't happy with it, so since I had this huge solar array, I got several ducted fans for RC Jets and mounted them in place of the vortex generators, so now when I lose roll authority I hit the button a few times and blast them with air and we are back in control!
😂🤠
…. Hmmm
my real flying kind of ended that summer when i had my first solo flight. that was when i was 16. 34 now with 15 years of aircraft maintenance experience and on flight sims since mfs95, back in rc planes for last few years (since high school), and i noticed a thing about alerons. had this lovely foam corsair, 1.1m span. loved to hover on strong winter winds with it... but, i wanted to go slower. i dug in to rx and tx manuals and found out i can programme ail droop with flaps. so i did. it sure brought stall speed down, but it more than halfed the roll authority.
i think that in droop mode, the up aileron should travel allmost the same ammount as not drooped one, where my tx progamming only eased it off about 70-80% towards neutral. i see scrappy is behaving in a similar manner. just a thought...
ps. because of You Mike, im thinkin of ppl again. Thanks
Merry Christmas to the Patey family and we your-“best” fans are looking forward to some new videos in 2022 if possible, enjoy and have a very merry Christmas…
For low speed "aileron" control, maybe consider secondary spoilers in the prop wash area (flaps?) aka the MU-2. Or having individual control on the flaps themselves. Or if you want to cheat, embed some bidirectional drone like motors near the wing tips. If you had speed sensing you could proportionally mix them with aileron input, and above a certain speed have lovers shut over them. Larger ailerons alone are only going to take you a little bit slower without really reducing susceptibility to gusts. You need airflow, either existing ( in the prop wash area) or what you induce (aka drone motors).
The reality you are the same place the X-15 was. Just not enough molecules of air passing over the ailerons to work with. Their solution was a reaction control system.
Glad to hear you are going to a constant speed prop
Patey ! Great to get an update on You and Scrappy. I guess You had to get the
slide rule back out to design/create Your Engineering Changes. I am interested
to see your engine updates. Lots of variables changing on the wing and power
plant, not to mention the prop. Sounds like another patent or 3 coming up.
Forgive me for this Mike. After seeing the RC Draco, and noticing a little man inside the cockpit. I thought I need to go to your website and zoom in on the little guy. I was excited to see if he looks like you in the RC plane. After zooming in, I thought wait a minute, that little guy has a full head of hair… Mike, you are a true inspiration. After working on my pilot license for some years now, you make me really want to fulfill my dream. One day, I will be finished with my private license. One day, I will meet you in person and shake your hand. You are a legend. Please keep inspiring so many people in this amazing industry. Thank you.
With the massive battery capacity Scrappy has a variable speed electric motor direct drive positive displacement supercharger would be a lot less plumbing with no waste gate and the complexity that comes with a dual turbo charger setup. Probably quite a bit lighter also when you look at the plumbing dual intercoolers and fuel management complexity. With the aero drag Scrappy has you probably want the power mainly for takeoff and climb, so time wise maybe 5 minutes max. With a VS superchager, just set the manifold pressure you want, set the fuel flow and you are good to go. Also lots of big PD superchargers out there to choose from that will supply all the air you want in that big motor. Separate independent oil system, a single intercooler and very little plumbing. Might be worth considering.
I was doing work when I got this alert. Gotta have my priorities. 😆😆
Merry Christmas Mike. I wish you and your family nothing but the best. Thanks SO much for sharing your life, your passion and your love of all things aviation!
P.S. Scrappy is on my tree this year!!!
Just wanted to thank you from afar. I grew up around airports and GA as my dad flew cubs and huskies for a living. Spent summers in hangars helping our local A&P repaint planes. Read every aviation book in the house and our library but circumstances and other aspirations kept me from learning how to fly. Your content has really helped to "re" spark my interest in aviation. Finally kind of have the means to pursue at the young age of 54. Picked up a 150 a couple of months ago and am now taking lessons (a whole whopping 5 hours at this point...lol). Keep the content coming. Just your vids alone are sparking interest out there. Now If I could figure how to fit my Pivot MTB in the back of the 150, I'd be set :). Great stuff. Keep it up.
Wish My Grandfather was around to see your videos. He gave me my first plane ride, in Arrow II. His first plane ride was a B25, to chill beer over the pacific. for him it wasn't about the beer, it was the ride. one of the engines caught fire. thankfully he didn't have to bail out, because he grabbed the wrong pack, and not a parachute.
Thanks for all you and Mark do for the love of aviation. Have a Merry Christmas and a most blessed new year!
I hit the thumbs up before I watch ur video.....sowing (giving back) to the community is a key that unlocks incredible reaping (blessing) and is a spiritual principle that works beyond measure. You have demonstrated this time and again Mike. Thank you for sharing.
15:00 "That's not available, so, I'm making one!" Why we LOVE Mike Patey!
Mike, you are a wonderful and generous person! An aviation genius with a BIG heart! Thank you!
Thank you so much for the amazing gift guys!!!! Love the scrappy spars and the extra goodies . Merry Christmas everyone and all the best in the new year
Hope you don’t mind me offering this thought. Instead of extending the aileron, is there a way to take a bleed from any of these; engine or prop wash or electric compressor and blowing it over existing aileron at low speeds only?Kind of reverse of the Formula 1 blown defuser.
I thought about that too, but concluded that plumbing the airflow needed would be too interesting given everything that's already in the wing.
I need to rewatch the wing build but I recall there is access and space. Having watched these videos for sometime I would never rule out work or difficulty as a reason for not proceeding with an elegant engineering solution. Having said that I think there are some options to do something at the aileron if you have enough information about what angle of attack you start to lose flow.
Mike, put a tow hook on Scrappy!!! I want to be the first glider you tow in Scrappy!!!
Dude! YOU are a perfectionist...but thats good...we need guys like you..
I can’t wait to hear and see scrappy with twin turbos. This plane keeps getting more and more insane. It’s only a matter of time before you add a JATO function. I was also wondering if you thought of some sort of spoiler on system to help with some extra roll control.
I made a bet long ago that twin snails would be the route you went. Guess I can collect on that one 😀 Awesome video as always, and love what you are doing for others!!!!!!!
Ha!
Nice ! Mike Happy Holidays to you and the family... Great new video and all your videos, 6.3 likes and no dislikes amazing Got one question and do wonder if you had both airplanes how would you use them for different backcountry outings?
Great to have gotten the Scrappy spar components here in Ireland for Christmas - Thanks Mike
I can not wait to see what will be done next to scrappy. Also thanks for the support of Veterans. I myself served four years in the USCG reserve.
The F14 used differential horizontal stabilizers to control roll. With that big prop pushing the air (and the need for rear ballast when you add that CS prop anyway) maybe you could look into engineering something like that to help your ailerons out?
A couple too many great ideas tried all at once. My greatest wish is you allow (or design) a Partey Twin Wing for RV aircraft. Longer, thinner, and able to land 15 knots slower while increasing miles per gallon at cruise and top speed to a degree that seems incredible
An airplane wing has thrust just like a prop: it displaces a mass of air downwards and that is the force that makes a wing lift a plane. Fight me.
Equal and opposite reaction. Push down a ton of air, get a ton of lift.
Very cool. I'd love to stop in and see it sometime.
You are awesome Mike! Thank you for sharing your time and talent with all of us!
Mike Patey you sent my son a ornament and stickers and I can testify that you do give BACK to aviation. Jason just wants us to pay it forward pray for us please sir I’m trying to get my A&P but I worry every day about paying for it. Thanks so much for your gift I cried my eyes out because I couldn’t really even afford it but because your group is so kind he still got this amazing gift. You always say if you can make a difference in 1 person your good..... Back To Work
Haha, called it! Not just one aspect, but two...constant speed prop with beta, and inadequate ailerons. Flying that slow with stock ailerons and then making them droop, it's like a negative feedback loop where you can't get slow enough to really utilize the flaperons because you lose aileron effectiveness as a result. I was half expecting the turbos too, but was hoping to see the nitrous work with a constant speed prop first.
Holy Smokes i won the Draco!! Thanks Mike, Jaime
Congratulations
Congrats to the winners
So jealous!
Cool idea to have some extra wheels on the wings for extra rough bush landings. 😁
I went to your shop and the Draco ornaments are already sold out! That's amazing! A great update and thank you for being so honest about the positives and negatives you've experienced with Scrappy. Now, how about an RC Scrappy....
