I love seeing alternative engines that are successful. More excellent content! Thanks!
@JP White... You keep showing up! Thank you! Thank you for watching and supporting here. I appreciate You!
Amen, it puts the experimental in experimental aviation!
Well my experiences from snowmobiles would make me very comfortable flying with an Apex engine, not that Rotax is bad in any way but Yamahas engines is a little bit better. Besides the yearly or every 4000km oil change I'm still waiting for the first service on the engine in my Apex, valve clerance check at 40000km or 24860 miles. :-) When the clutches are set and work correctly it should rev about 10700 at WOT, the revlimiter kicks in at 11000.
It’s about time we realize that air cooled carbureted engine with magnetos is old music. High performance motorcycles and cars abandoned that long time ago....
Carb rebuilding kits, and tuning talents are few and far between also. Motorcycle dealerships won't this old tech anymore.
dealerships won't touch
Magnetos are still used in top level motorsport.
Bill Hollingsworth are they? Wear? I though mags didn’t let you change timing so they wouldn’t work with FADEC systems.
@@joshmoore6165 You know you can edit comments. Not trying to be difficult, just if you wanted to fix the original comment you can.
Hi there
I found this video very interesting and I loved it, but
The search for power is - in itself - a never ending quest ingrained in american hot rod culture.
And there are those who strive for more and more power but
In aviation, I believe, it is reliability every pilots main concern. Thus redundancy is mandatory in every mechanism
I would find it extremely interesting if you could do a video on Viking Aircraft Engines
Here again is a company using automobile engines in aviation
But with a different approach
That of reliability
Power can be achieved but their approach is one step at a time with reliability as first and foremost priority.
Please do the video
These price points are ludacris. I'll go back to machining if this is what people are charging. A turbo kit plus remapping is 5000.00 for a Apex. How the hell can you add more then 5K to the price for bolting a kit on? This is a great Idea, but not practical.
Matthew Drehobl yea I totally agree, the whole idea was to save money otherwise why not just buy a ULpower, Rotax, etc. used Apex can be had for 2k, but that skytrax gearbox is just robbery.
I can pick up a Rotax 915is for $40k CAD. Sure, it's no 300hp monster, but it probably has a longer TBO.
It seems like you should be able to get an engine out of the crate from Yamaha, and not an extracted snowmobile engine.
Yamaha doesn't want to get involved in Aircraft engines I can understand why then they can be held responsible all comes down to lawsuits. Even if they sold them to be used in snowmobiles still probably end being sued. Attorney's go after who ever has the deepest pockets eventually someone will crash and end up dead. Families are filled with greed by attorneys who want to make a fast buck on a settlement.
@@Mike-01234 that's why you can't start or run their cycles in gear with the kickstand down. Some brainiac did, and collected a payout for his own stooopidity. ) :
chekyerego - In all the years I’ve been around bikes, I’ve never seen a factory complete engine available. It’s a damn shame, too.
That would be nice. In the early years I was investigating options for engines to build "Reverse Trike" kits. I think the only manufacturer that might sell a crate engine (or maybe just in individual parts) is Kawasaki. Most Reverse Trike kits now use doner bikes be it NEW, Salvage or low miles used. Thank you for watching and supporting here. I appreciate You!
Experimental Aircraft Channel - Ahh great info, Bryan. Thanks!👍
That price is ridiculous. I can't comprehend how he can justify 20k-40k.....
I agree, im not sure why a person would considered this motor when you can get a new Rotax 915iS fresh out of the box, turbo and fuel injected, (which btw you will get service bulletins should issues be found at the factory) all for $37k. In contrast I'm sure the APEX works well, but seems very expensive for what your getting, a used, secondhand engine. If it was a $6k or even $10k maybe. But $23k? Hard pass.
If you go to his website and check out the price page he is offering the Rotax and Yamaha. The 150HP EFI Apex is (w/firewall forward prop and hub) $23k the 100HP Rotax 912 is $28k (FF inc) the 914 is $40k (FF inc) The Yamaha 300 HP is $43K. There is a rather large difference between the HP and whats included for $43K. In neither case are you buying just the engine. For 300HP ready to mount isn't that ridiculous. Yamaha makes a great engine if they provide the correct modifications seems like a fair price.
Shouldn’t even be a second thought between carbs or fuel injection. I mean absolutely ZERO thought really. Also, you shouldn’t even really have to develop and R&D a turbo system for the Apex, the snowmobile guys have been doing it for years and years. I completely understand a few tweaks and bugs here and there, like exhaust manifold/collector, charge pipe/induction manifold routing and intercooler maybe if your using one. However, the fuel mapping, computer, proper turbo, etc.....there are many many guys who have that down perfectly. Certainly shouldn’t be necessary to start from scratch just because it is going in an aircraft right?
The mapping for an aircraft is completely different from a car. I've done it and the maps that were provided with the ECU were completely inappropriate and I had to start from scratch. Been flying with my setup since 2009.
Something used on a snowmobile doesn't necessarily fit or work on an airplane.
As he explains in the video, he had to come up with his own exhaust system because it can't be fitted the same.
And with different gearboxes and ways the power is used at a higher band of altitude changes comes the need for different mapping and adjustments.
Wish I could subscribe again! but again I really like these videos with Steve and the Apex!
I always thought the point of using alternative engines was to lower the cost. Yes, it's a cool engine but damned pricy. And you're basically getting a secondhand engine.
exactly what I was thinking. If im handy enough to build an airplane from a kit then ill find a 2nd hand engine rip it and and install myself. Of course ill buy what i need like the fearbox but holy crap iv seen these engines going for 2-3K.
but let me add that if you have the money to throw around, if your looking at a highlander Id sure throw it Steve Henrys way.
@Ryan You can buy a used APEX sled for $2000 or less all day long. I know because I have one. Lovely engine, its true. Its as smooth and happy as can be to squeeze 11K rpm all day long and lots of guys have huge miles on the sleds with no engine issues. Maybe I can sell my sled for more money now lol
@Ryan You don't need 20k to turbo.an R1 engine (what an Apex essentially is). Maybe 5k.
yeah, but what's the TBO. Sure i ride high performance sportbikes, sometimes at high rpm for the thrill. But i don't think it would make any reasonable TBO doing that long term. 20K+ for one of these whizbangs? When it quits on a sled no one thinks about it---it's when your with your kid drivin' over the mountain that you think about it. Nice vid though.
Have an interview on the Skytrax reduction gear system for the Yamaha snowmobile engine, hoping to get your permission to use your video footage of the unit being used, showing it taking off and landing - I will, of course, acknowledge the source. Thanks The Ultralight Flyer

I had a Yamaha snow machine for 4 years before I sold it when I moved to a non-winter state and that whole time I never had one mechanical stoppage or any issues for that matter. My riding buddies with SkiDoo's, CanAm's, Polaris....none of them can claim that. I carried a strap and D shackles to pull them when they broke down lol Yamaha is KING of the snow machines!
Kinda related, I've got a 07 Yamaha Rhino 450 on the farm and use it every day still runs like a champ. The Polaris Ranger I bought in 09 is usually broken in the barn waiting on parts. They do the same job, same loads.
dwarden3 , same here in Ontario. Our ATV group always ends up having to repair or tow a Polaris back to camp. Yamaha , Honda and Can Am never seems to break down.
Bryan was Mr. Henry’s engine issues the MAPing due to a horse power cure difference in different power needs along the cure? Another great informative video. Love these different approaches to experimental aircraft. You may want to suggest this idea to AGAN aircraft designs because I bet they would love this amount of torque for their designs.
Great idea! These engines could serve many applications and many platforms. I not sure exactly on the mapping for each mode (STOCK and BEASTMODE!) :-) Thank you for watching and also supporting here!
Experimental Aircraft Channel I would be interested in his fuel consumption on max range? If you get a chance to ask him? I was thinking KitFox but after hearing your interview I’m now rethinking my thoughts. I wouldn’t be in and STOL competitions but with that much horsepower at your fingertip! WOW. Nice to have it and not need it and if the gearboxes can take the TBO times then why not!!
Ive made 350hp turboing the apex.
where's the best place to buy all the apex gear, hardware, turbo's etc...
Excellent video Bryan! Been waiting to see what Steve Henry was putting together for this year. Exciting stuff
Thank you! It was a long ride from Florida and back but....apparently worth it! Thank you for your feedback! Thank you for watching and supporting here. I appreciate You!
We are using one in out Avid.
About RPM - - - I had a Honda CX 500 motorcycle in 1969 that red lined at 10,000 Rpm and everybody said it was a time bomb because of such high RPM. It was the most reliable Bike ever.
I could take it up to 10,000 RPMs every shift and I often drive in a lower gear to maintain the 10,000 RPMs and it was only a 2 cylinder so RPMS mean nothing if the motor was designed to be a high revving and built by a good company Like Yamaha or Honda.
Don't bikes today rev 20K now?
@@SVSky Most of your average sport bikes are topping out between 12-14k. My 19 year old Blackbird redlined at 12.5k. Happy zone was between 6-9k, and best mileage was around 85 mph.
@@SVSky many do, but my Goldwing redlines at 6,000.
the CX500 didnt come out until 1978.
@@yamahale Thank you Hal you are a better historian than me. But point being that it was a high reviving from a long time ago.
Great to see this engine in a plane, but these prices are just absurd : a mid-condition apex engine goes for 2k, the gearbox is 3k, a turbokit is 3-5k. nowhere near those 43k he's talking about.
That list prices that Cristhopher is showing belows shows why. Everything incredibly overpriced. 750 for removing an engine? 500 for cleaning it? Completely irrational and overpriced. You can get a good used engine for 1K and if you know what you are doing, save thousands.
What's the fuel burn rate at cruse?

Why such a price increase for the turbo version? +$20,000? ....I have done a bunch of different turbo installations on everything from motorcycle to V8s and just can't see that much of a price increase on a snowmobile engine.
I think plenty are missing the point. Like saying I want an SUV so trophy trucks are garbage. This engine is one of the best engines this size ever made. You want performance? Usually costs. Also, love this engine in my motorcycle.
Thrust from Steve Henry engine is amazing. Power to weight ratio is nuts! Had a Yamaha 650 4 cylinder that redlined at 10,000 rpms in early 80’s in a motorcycle. R and D has been working overtime for sled engines though Yamaha in the later years. All about speed and weight! Hats off to Steve Henry for test piloting this project that so many want to acquire now for an airplane. Great question and answer session. Well done video.
Thank you! Very much appreciate your feedback. Thank you for watching and supporting here. I appreciate You!
@@ExperimentalAircraftChannel you NEED to seriously look at the 300hp supercharged jetski engines...theyre marine quality engines with jetted oil cooled pistons for continuous high rpm...really torquey engines out of the crate
this seems to be the old engine used in VX jetskis. it had about 140-180hp and a redline above 10k. the newer engines are much better and more powerful.
after watching him compete at arkanstol I can say these things perform. The sound this thing makes is amazing!
AWESOME..... That TURBO needs a 2 speed gear. Super Cruise....
🇺🇸 🇺🇸👍✌👀🇺🇸🇺🇸
So is it not possible to get a new crate engine from Yamaha. Or is it just more cost effective to get them ex sled. Maybe you need to be talking to Yamaha, could be a deal to be made there. I wish GA aircraft had this option
I’m putting a yamaha Apex in my zenith 601xlb project. It should be a blast when it’s all done

Need vid!
that sounds fun!!!
From what I'm hearing about price points and the technology in each motor, why not use the 3 cylinder Genesis factory turbo motor from a sidewinder and just do some mods for reliability with high boost
When you fly thousand of miles over ocean mountain and jungle you will think differently ,, 8 - 9000 Rpm are ok to impress yourself around the pattern ,, but the real thing is the big bore slow turning direct drive Lycoming humming at 2200
A 500 cc Honda, twin, 47.5 HP at 9000 RPM, lasts easily 100000 miles. That's many hours before TBO. Change of oil every 5000 miles, check the valves every 15000 miles, never touched the ignition nor the injection. Mine began to sip a spoon of oil at 110000 miles and I opened it because a ball bearing in the gearbox was becoming slightly noisy, so I remade the engine before selling the bike to a friend. I'm a maniac in mechanics.
In Germany on the autobahns (no speed limit) I make easily 150 miles full throttle full speed, before refuelling.
The engine of an ordinary road bike Honda VFR 800cc 4 cylinders 100 HP has been tried on bank 100 hours at 8500 RPM without problem. Yes 4 days 4 hours at 8500 RPM non stop. Inside it was pristine. They were testing a synthetic oil.
In endurance competition, a 1000 cc Suzuki giving 220 HP at 12000 RPM makes easily the 24 hours at Le Mans , and the circuit has a very long straight line of 4 km (2.5 miles) taken by the bikes at 200 mph and more at full RPM.
It's simply good engineering.
The assumption in that statement is that lower RPM is better reliability in spite of performance and efficiency loses right?
Except the auto industry has long since proven those assumptions wrong. Delivering increased reliability and performance and efficiency.
Ya for long life slow low RPM is the smart move. Lubricated metal on metal
lasts longer with lower RPM. Lower temps equal safety.
@@MrAluminox look i have a hayabusa, and a 1968 cessna T210. I can get maybe close to 1400 hrs before changing out a cylinder in that continental engine if i don't let it run too hot. In aircraft we are cruising at maybe 65% power at CONSTANT rpm. We just don't drive motorbikes at CONTINUOUS high rpm. Hayabusas run at the dragstrip and get rebuilt very often, relatively the same technology as this yamaha engine in question. Of course i could be wrong here, but some TBO numbers would be interesting.
@@Mrcaffinebean the technology is getting better but you do not cruise any car at high continuous rpm for very long.
Great video! Thanks. Have you thought about a visit with Mike Patey to see what he is doing with carbon fiber?
7.000 - 11..000 - 8.000 . 9.000 - RPM information is rubbish ---> power and performance : nearly NOTHING ! spoiling 12 minutes of my time
I’m looking to build an Van’s RV7.. thanks for the video! Keep up the great work!
Could someone please explain to me why he couldn’t just put EFI onto that carbureted engine?
You can depending on the manufacturer. Yamaha is known to have different valve spring ratings between the two. So you would have to re-work the head. Then rebalance the crank. To do all that DOES NOT cost that much.
In Australia so we don't see too many snow mobiles. Are the 1800cc 4cyl engines used in the WaveRunners a similarly usable/ reliable engine package?
First Vid I watched on this channel! Subbed! I’m a huge fan of the Yamaha engines, in general. Gonna be interesting to see how these fair in the aviation world!
I’d love a highlander with a yammi, how much would a complete kit run?
Any promo vids on them anywhere?
Thanks
I have a 2009 Apex MTX with 1,800 miles on it. Like new condition. I plan on keeping it, but after hearing the going price for the engine, makes me wonder.
Apex engines in mid-conditions go for about 2k, that guy just wants to make a huge margin
I guess that if he can sell them for that, more power to him. The price of aviation anything is why I'll never get involved in it. What makes the sled heavy, is what makes the plane light. Funny how the different applications work.
I can buy a while working sled for $3000.The engine harness for aircraft is 125 bucks or so.Test the compression and throw it on.
Rotax,made a huge change in the light airplane world with snowmobile engine's, I look forward to what Yamaha can do
Ridiculous how expensive an aviation engine can be. $30,000 for 120hp? An automotive engine experiences allot more stress and is more durable. Why use a motorcycle or snowmobile engine if you still have to pay the price of the plane for it?
Mega rpms scares me. It only makes sense that overhaul times are going to be less hours. Besides, the noise would drive me nuts. High power, lower rpms is he ticke to long life, dependability
So why would anyone pay 23 thousand dollars for the engine and redrive, when you can buy the engine from a Yamaha dealer and components for well under 10 thousand dollars, and then purchase the prop drive separate, and bolt it on.
Thousands saved.
You can buy the whole sled brand new for 15 thousand or less.
Forty thousand for the turbo version, fat chance.
Everything aero is ten times the price of automotive. These planes are one by one hand made, Henry Ford had more production automation 100yr ago than what many airplane manufacturers use today. Its just economy of scale. The comparable hp rotax is more than $23000 and it is an old design with carbs. If you want injection the rotax would be even higher price.
Scott Nunan
crazy! Good point
i agree to a point!! the engine has to be modified, and preped for air!! i have a shop and can do it my self so i would not pay that much but if you cam to may shop had me get one ready its a lot of work now maybe something i dont know as way 20,000 extra for turbo?? maybe 10 at tops?? but maybe i to cheap??
Plus you can get it with the right turbo for the engine already attached
Just can't get enough of these Yamaha engines... "New sponsor acquired." Congrats! 👍

Can you replace RX1 carburetors with APEX fuel injection system?
I'd love to see someone put a "real" 2-stroke into an airplane. I've seen a couple done, but it's usually some hopeless cheapo engine made out of butter and sadness, or it's a dedicated aviation engine made out of money and sadness. 2-strokes are light, simple, and not as inefficient as you'd think when fuel injected and kept in their "happy place" RPM range. People think they're unreliable, but most of the time problems arise from them being different and owners not knowing about it. The amount of hokey legends and old wives tales I've heard about the various vintage motorcycles I've owned is incredible. Fortunately with fuel and oil injection all the tuning items can be dealt with by an engineer, and all the owner would have to do is monitor CHTs and not let it run out of oil. Then when you do have to overhaul it, it's a 2-stroke so it's like a 4 hour job with a friend and a pizza. But until then, I'm just happy to see the aviation community starting to use any engine that's not just a giant VW at Ferrari prices.
23,000 wow, you can buy a Piper pacer for that.
I try not to support foreign products. I’m just American.
will it be useful to use a reduction belt instead of a gearbox?
Man this gives me an idea to take a look at Yamaha's SHO watercraft engines. Not sure how well they can adapt because they use water from their surroundings to cool
great video! what about the yamaha 1800 from the waverunner gp1800?
Great question! I was looking at those as well. I see Yamaha has a manufacturing center in GA. Maybe I will go visit them one day.
@@ExperimentalAircraftChannel please do these are some awesome motors!
for the big experimentals we should see more chevy LT motors, these pushrod engines are light and compact
IS the $23k price for a non turbo engine include a rebuilt snow mobile engine with fuel injection ?
That includes the gearbox and prop as well. You're talking about a motor that weighs just over 100 lbs, and rebuilt can easily make more power. My 2008 R1, it's a similar motor, made almost 180 with a full exhaust system and dyno tuning on a stock motor. Match the ECU map for the use, dial in the cams for where you want them and tune it for best power application. Non turbo super bike builds are making well over 200Hp.
damn that is big money for a engine almost 50k for the turbo forgive me i dont know anything about airplanes
Remarkable video. Great interview, super products. Well done. (from a Brand New Subscriber!)
Welcome! And...Thank You!
Hey! do you have a 3d model of this yamaha motor engine?
If Your Sponsored by Grip Lock Ties. Could you please make a Behind the scenes video and interview with Mike Patey.
Coming soon!!! ;-)
Its racing, I get it but man the fuel bill must be a bitch.
EFI is so much better fuel economy than carbed.
Wonder what the fuel burn is at 8,000 and 9,000 rpm?
Not so true in an airplane RPM doesn't change all that much where in a car have to change the RPM lot more often. Also lost more electronics can fail cause engine to stop where old school aircraft engine as long as the engine keeps turning mags get power. Probably not so much to worry about in a STOL aircraft like Steve's he can land it in someones driveway or a roof top only needs about 20 feet.
@@Mike-01234 I have flown both and never had an issue. EFI starts easier and has no vapor lock issues. As for electrical power loss, hmmmm, thinking how many times I have lost electrical.
blastman8888 Mags and EFI are two different things. EFI is induction, Mags are for ignition. Which is not to say they can’t be integrated......
Can't go wrong with anything Yamaha.
Wow! So it has a 0.99L engine? A 59CI engine.
Is Steve running Earls waterless coolant?
you can buy the jet ski for $14, 399 brand new and direct from skytrax the gearbox is only $1,495 & all you got to do is put the gear box on and put it in the plane why would anybody spend $23,000 for him to sell you the motor when it's only $15,895 price tag to do it yourself complete doesn't make sense to give somebody an extra $6,000 and some change almost just to bolt on a gearbox $6,000 and some change just to bolt on a gearbox seems pretty damn Hefty of a price, just a bolt on a gearbox that only requires 8 volts to attach it to the motor I can't imagine what the complete airplane with the Apex motor in it costs from this guy, & another $20,000 for the Turbo Charge system, wow, what does this guy think his shits made out of gold, he's robbing people, he's a crook, if people would only do a little homework
remember, hes getting the engines used. I dont get it either but people must pay for it. Maybe there's some other things he didn't go into?
Carl, this man is running a business, what he must charge for his product after figuring out the overhead, his time, and all the other costs that come up with his business, and maybe some for profit is his choice. Now the decision to buy his product, or not to buy is yours. Do as you please.
Ok you still need to add a prop, engine mount,and loom, this is in his price.
I wouldn't have qualms either if I could land in a bird's nest. Steve is not your average pilot.
valid point.
AIRBOAT GUY HERE----- im very intrigued. what years of APEX sleds are the best? what does the gear box cost?
09:38 , i was waiting for the money shift.
What’s the engine life on these 10,000 RPM engines?
I know nothing about snowmobiles but that rx1 looks suspiciously like a R1/FZ1 motorcycle engine that i know well, will do 100,000km street miles or a full season road racing no problem . Seemingly built from kryptonite.
@@watsisbuttndo829 yep, based on R1
I had an R1 track bike with over 20K track miles and the valves didn't need adjustment at 20K. I had at least another 4-5k put on it to the guy I sold it too until someone crashed it on the track.
I know people with 20,000km on a yamaha 4 stroke sled motor. Sleds get run hard, harder than in an aircraft. Running lakes, rail beds they are WOT for long periods of time. In the trails they get beat on, 0% throttle to 100% throttle from corner to corner. You will never beat on an aircraft like that.
So what would the TBO be for one of these? Rotax has a 2000 hour TBO.
Is that motor going to jonas?
Why not the 3 cylinder engine from Yamaha Nytro? Lighter and very reliable. 130hp stock but MC Xpress from Sweden pulls 340hp from it very easily.
270 degree phase in power pulses gives propellers some funky behavior.
@@CommieCat Aah. Thank you for the info. I have absolutely no experience in aircraft engines. 😁
I’d prefer the nytro engine
what is cruising speed?
I said in a comment months ago, that these conversions will not be any economical than a cinvenstional aircraft engine and I am right . 23k for a used sled engine with a gearbox. Who thinks that that makes sense and a turbo version for 20 k more holy fuck batman. That's close to a certified Lycoming new 540. Seriously this is fucked. I'll stuck with a Rotax 912 thanks. They are known to go way past 2000 hrs of reliable service. What malarkey.
videoclipits thanks for lucid comments, doubts and questions...these are drag race, STOL engines to compete and climb 3000 ft per minute...too narrow a use band and undetermined engine life....interesting, but...
Do your own conversion. Source your engine, buy a gearbox, wiring, headers and engine mount. Could do for $8k +- It will be alot of work, but if you want plug and play you will pay! Rotax not cheap either....
That was 23K for a rebuilt engine, gearbox, prop, wiring harness......... Buy the parts yourself and you could do it for less. What would it cost to buy a complete rotax that makes 150 Hp?
@@craigsanders6925 More. There are companies out there doing big bore, turbo and EFI kits but you are paying anywhere from $6k to $20k (just for the kits!) in addition to your whatever you pay for a 912. If you buy a complete ready to run modified-to-150hp Rotax 912 engine you will find the Yamaha at $23k a total bargain. A new 140hp Rotax 915 is $35k.
@@mr-uc4me I knew the answer, the price from Steve is higher because he's doing all the work for a plug and play install. People just don't seem to understand they're paying for a service to go with that motor.
I would like to see the Kawasaki H2-R Supercharged engine in something Built For top Speed. Plane built with carbon fiber. Or a Ducati V4
I'd like to find out what these engines weigh? Not turbo.
130 lbs non turbo.
Found it out on another guy putting one in his kitfox, he actually weigh it on his channel for everyone to see.
Whats the weight of ready to bolt on apex engine with gear box.
I was there when he took deliver of the Turbo version of it. We through everything on it required to run while it was hanging from the hoist. Came in at 199lbs! So the normally aspirated (STOCK) Yamaha should be much less. 185lbs or less I believe. Thank you for watching and supporting here. I appreciate You!
@@ExperimentalAircraftChannel 200 pounds for 300 horsepower is a hell of a thing.
Question for Steve, Which Wing ( Highlander or Super Stol) Is better for low and slow? Ideally, the Super Stol with the highlander landing gear seems better overall for Stol, but.........................
What does it weigh?
I am wondering what makes the Yamaha engine competitive compared to a Viking 195 or an aeromomentum engine. Is it the weight? Doesn't seem to be the price.
Not a bad engine...but I also don't see too much R&D on these either. I'm not too sure I'd spend that kind of cash on something so unproven. Aeromomentum is doing a far better job on the R&D front (easily the best of all the auto converters out there IMHO) with significantly lower prices. I'd approach this one with caution till a few hundred hours at least are on a few of these. If it works out okay after that, fine. If not....
I haven't seen the weight for the turbo setup, but it has to be alot lighter than the honda auto conversion. These engines also have a lot of history and testing of turbo setups in the sleed world. They have proven to be super reliable in that application. That doesn't mean I disagree with you about hours of testing on this specific turbo/fuel injection setup. The fact that you are not getting a factory built engine also adds variability that I don't like. And the price... 40k ouch
About 115-120 lbs, that was his price that included gearbox and prop which I'd guess costs about 6K.
cool video ...... :-)
$23,000 for a second hand motor with 150 hp is pricey. Those Yamaha motors can be found used in good shape for about $3000-5000 so $23,000 total cost is really high. Might as well go back to the Lycoming-Continental!
Even race engines don’t run 80% load for 4 hours. I think you’ll need 10 of these to last as long as a Lycoming.
Nice !
WWOW More horsepower and control over your prop. At Half the price of a Rotax!!!!!!! I wonder what the weight difference is.
Nice interview, thanks! Who makes accessories for APEX and PHAZER engines: mounts, gearboxes, airboxes, exhausts, etc. Anyone running these on Powered Parachutes? Thanks!
more like VTOL
I know Rotax makes aviation engines but I would think a Rotax 4tec supercharged 3cyl which are used in seadoo jetskis would be a fantastic experimental aircraft engine. Is anyone doing this?
Engine price??
I just bought a 2011 1000cc Apex, operation Yukon is a GO haha
I love the plane and the performance. And did they think that you were going to say a couple of hundred $ for the engine.?? I think that it was Rolls Royce who used to say "if you have to ask the cost Sir, You can't afford it",!
Does anyone know aproximate concumption per hour for this Yamaha Apex conversion, at 50% of power?
You got my sub simply because you waited until I could watch enough of the video to know if I liked the content before hitting me up for it (smart). Nothing sillier than "Before you watch the video and see if you like it, be sure and hit 'Like'".
Of course the content was great too. :)
Outlaw Motorsports in BC builds some monster yamahammer engines and there was a place in enterprise Oregon that did as well…
Why not bike engines when they are more easily available and probably cheaper?
Because motorcycle engines have a heavy gearbox that isn't needed. These do not have the gear box and can be mated to a proper ratio gear reduction. Thank you for watching! :-)
I was wondering the same thing.
So in other words nobody has pulled the transmission off of a motorcycle engine and figured out a cost effective oil pan with an engine mount.
Imagine a turbo'd zx14 or busa in an 800lb airplane.😲
@@fz671 Most bike engines have the gearbox integrated to the block.
cool videos, sir!!! and Mr. Henry and the Yamaha engine is exciting!! new stuff,,,, good!!! come on Honda!!!!!!!!!!!!!!!!!!!!!!!! just sayin
Reading some of the comments below what is the difference in engine fuel injection mapping between a snowmobile and an aircraft application? If the snowmobile fuel injection is wide enough to go from sea level to 10 thousand plus feet why is the aircraft different?
Интересно блок двигателя дюраль, как он противостоит нештатным нагрузкам?
Fuel burn?
Is that Steve Henry website ...we can brought the Cessna or any aircraft be New one or second hand .....?
How much to turn my RS Venture engine to a plane chassis? And get my small plane licence?
amazing!
