RC Chinook Bicopter - Part 1
ฝัง
- เผยแพร่เมื่อ 15 มิ.ย. 2024
- Could this be a budget way to build a flying model Chinook? Using the bicopter method of stability and control, the complexity of the Chinook should be able to be greatly reduced over using two full helicopter rotor heads. As mentioned, bicopters aren't anything new and I've been wanting to build this for a number of years now. Thanks to you guys, I'm now able to build what I want!

I love your videos, informative, easy to follow and you articulation is wonderful.
Thanks!!
Couldn't agree more. I'm not really into any of this stuff but I find your engineering skill and videos amazing! Just really really interesting stuff! Great fun. Cheers
Everything he said 👆🏽
ㄴㅇ고스톱 ㅜㅏㅏㅡ
agreed
Maybe you could include the parts you're using, i.e. motors, servos, controller board and controller software name, remote control in the video description.
Very obvious amazon referral stuff.. 🤔
at 1:10
"can barely bend it"
rollingshutter effect: "Hold my beer"
its rotating a camera so fast the object is looked like a bend object
My brain completely tuned that out.
Haha yeah
Like a twist even
The thought process and the trial and error in the build are really interesting to watch. It makes a pleasant change to see intelligent content that focuses on engineering alone. I shall now watch the next part.
You will be gold in the aerospace world. I was just like you 5 yrs ago and now work at a large aerospace company. I wish more engineers had a background like us.
I'm really liking this style of videos! Keep it up :)
Agreed!
Me too!
Same!
Yeah i agree, but i want more information about how he connect the parts like flight control.
Spent 14 years flying the CH 47. They are very unstable and use 2 AFCS systems to help to stabilize. The swashplates do tilt forward automatically as the aircraft accelerates to help level the fuselage which reduces drag in high speed flight (170 kts).
I must say, Tom, that I love the way you go the extra mile - the little professional touches such as the inclusion of the CAD drawing @ I:20 complement the high quality in terms of projects undertaken and concise, informative explanation which I´ve come to expect from you.
Very well structured video. The perfect amount of detail for those who are knowledgeable of DIY RC to know exactly what's going on, but I completely understand the appeal of going into further detail and analysis. Ignore those who are upset that you won't be test flying until next week's video, great things take time!
10:01 second and no extra ads. Something very satifying to see:) Also:KEEP THIS PROJECT ALIVE! I look forward to next friday. You deserve the extra money for more videos. Mkre videos= more views from already subscribers and the algorithm might like it;)
This is one of my favourite subs, great content and a great presenter - down to earth and mild mannered
Cool. I love that cr-10 printer. And it’s one of my fav helicopter aswel. Hahaha thanks
Although I had not heard of bicopters, the principles and how they apply to this tandem configuration were apparent in the first minute - nicely done. 🙂
Great videos Tom! I love watching them!Can't wait to see it fly!
Looks very cool. Can't wait to see final product. But whats going on at 8:15.....looks like the forward motor has a mind of its own.
It seems that when the PID gains are too high, the motors tilt when spun up on the ground. I think the vibration causes it to drift and it doesn't self centre because it's 'fighting' the ground. Thanks!
Thanks! Your videos are not only entertaining, but incredibly informative. Cheers!
maybe a too high or low I (integral) value
Yeah, my racing drone does a similar thing if you take the props off and start it on an un-level surface when in angle mode. the motors all start at about the same arming speed but eventually the lower motors will accelerate to full throttle. with the props on, this will simply level the craft more efficiently. I think this is because of air mode?
I've often though of a build like this. Great video as always!
Sweet! Looking awesome already! :D
Another great video! Keep up the hard work, cant wait to see this fly.
Can't wait to see that bad boy fly! Looks great, really enjoy your videos. Keep up the great work. Happy flying. 👍🏻
The videos you make are very interesting and definitely getting better as you go. I liked this format a lot, just throwing my vote out there.
Oh, this is an awesome project! Thanks for sharing.
Excellent project, can't wait to see the next part!
Looks awesome! Can't wait to see it fly.
This looks awesome, keep it up! I love bicopters
Fascinating project, Tom! I'm looking forward to seeing how it performs. Cheers -
Video incredibly informative, I'm working on a drone now you inspire me!
Excellent job, i cant wait to see it finished.
Brill! You do all the stuff we dont have time to tinker with haha cant wait to see the results!
Extremely interesting channel discovered by accident. Glad I did. Subscribed.
Thanks. I like this new format.
This looks an interesting one Tom, I love the details and the way you work through them. Off to Patreon now :-)
I loved this. Great job man!keep it up 😍😍
Such a good video and an awesome project. Thank you for the detail on the build.
I liked it that you started putting videos in parts. This makes me more curious for the next video so i loved it. This is probably good for you as well, i guess.
hi tom looking like a great project as soon as I got the notification for the video with the word Chinook it immedeiately got my attention as that helicopter is my favourite all time heli im a crazy fan of all helicopters so cant wait for the next video peter west mids
i could make you a rc chinnok for 150 usd -120 gbp with body shell
I love how autocorrect misspelled your name
Tom I love the way you edit your videos
Terrific stuff!
I Like this format!
in case you haven't run across it, and no one has commented already, the CH-47 Chinook (pronounced shinook) has a main drive shaft which connects the front and rear rotors. the two turboshaft engines turn the drive shaft, and the drive shaft in turn drives the props. The drive shaft is a critical design element, as it keeps the rotors synchronized, and prevents them from colliding with each other in flight. One of the most dangerous situations in the Chinook is if a tool gets left in proximity to the drive shaft after maintenance. One such incident nearly sheared the drive shaft in two just by scraping on it while in flight.
One video every week? COME ON! I WANT PART TWO ALREADY!
It´s lovely so far, thanks for sharing mate! Subbed right away!
Great vid great build, looking forward to see it fly ;)
Great video, great project 😊
Awesome idea. I'll be following this build. Hope it all goes well.
Very nice concept and EXTREMELY well presented.
Ah looks good so far. Printed out the plane awaiting confirmation spars ....mail ...can't say I understand all of it , but at 72 it's fun to learn something new.... shouldn't be hard I have forgotten enough to make room for something new ...lol Take care.
Can we please all agree to say Chinook "SHIN-OOK"? Ok good, that's a relief...
slimigan it was driving me nuts too
Like you would pronounce Porsche. Like Porsch, without anything behind the SCH
@@andrslnks4804 I thought the Germans pronounced it "Porsch Ah"? Also can confirm being from an area where the indigenous Chinookan people are from it is indeed pronounced Shin-ook
@@DMSparky
No. Its an E. Not an A. Hard to discribe how it sounds. Look for german Videos with a Porscheeee. Never just Porsch. Greeds
@@andrslnks4804 por sha. There you go
You are awesome I'm looking forward to more awesome stuff from you.
Brilliant mate!!!! Great job!!!
Looking good, looking forward to next weeks video :)
Shin-ook, grew up around the real thing, keep up the awesome work.
Looks outstanding. Good luck with the rest of the project.
Awesome channel you have mate, really interesting projects.
Nice one Tom ! Keep the videos coming !
Waiting anxiously for the next video. Tks
Another brilliant idea mate :) Thanks for sharin'...
That high speed hammering was far too enjoyable
Another great video blue, keep it up.
Great video, Thanks!
This is cool. I made a ‘chinook’ a few years ago by combining two blade cx2s together. It actually worked better than I thought it would, but yours should work even better. I know it’ll look better than mine did.
Cannot wait for part 2!
thumbs up! I can't wait till part 2... plus I subbed, thanks..
Love your project and how you present it. Subscribed.
you are a legend man
Great Video :D I'm realy looking forward to the "in deepth videos"! great idea
Awesome video! Well done!
6:54...For driving angle of engines I recommend 2x longer (maybe 2,5x) lever against servo lever. Also should by better using spheric brass/plast joint. On all 4 point. In this cause you can used higher sensitivity of gyro and any inaccuracies in engine tilt will be much less. Also servo will have bigger power for flywheel resistance. The sensitivity range of the gyroscope will be used in a wider range. This means more data per angular degree. Self-stabilization will be even bit faster and mainly much more accurate. Any way, one from best video on this theme.
Nice hammering together edit. If only it was that quick!
That's actually pretty cool 👍
Great project
Never thought about a helicopter like this before.... A flying stick of aluminium! Can't wait to see it fly. Great work so far!!
Well done I love your CH-47
Aaaggghhh I need to see it fly!
Super cool! I also love how you're using a RF board but have Betaflight installed on it ;)
Keep 'em coming kiddo!
love it dude!
Amazing how fast he assembles the chassis.
Awesome stuff!!!
I love the fact we will get more vids sooner love the projects you do all the kinds of stuff i did as a kid but without the tech you have. have you thought about letting us give you ideas to try and build that would be fun i think.
The hammering together part made me chuckle
Great job!
can't wait till part 2
Amazing!
I love your creativity and the way you follow your ideas and instantly design and manufacture them and then - probably the hardest part - make them actually function in the real world and describe your learning curve. Usually the best designers are not very good in communicating and documenting but the way you do that is really outstanding - thanks so much, it gives me a lot of insight in physics.
There is only question about this specific helicopter project that I don't understand - having the rotor axis tilted towards the front, how would you ever be able to fly backwards for maneuvering? I guess the only way would be to sit on the rear brakes until the front has been lifted for the rotors to be horizontal and the fuselage it angled, you can maneuver normally. Must be quite tricky to handle in full scale real life as a pilot during take off and landing. But I guess the advantages in flight (probably more than 90% of the operational time) with the angled configuration are giving the fuselage a perfectly horizontal position which makes total sense. And there is the advantage that the blades can be having a much bigger radius, being more efficient and creating even more lift in the center of the fuselage where they overlap and they cancel the moment when turning in opposite directions - actually pretty genius.
I guess I just answered my own question :-).
Brilliant project congratulations.
Loved your explanation of the forces at play in an aircraft. Might not be your forte, but you should do a video about stability in water vessels, how righting angles are derived from centre of gravity/buoyancy, metacentric heights and the difference between list and loll. A build with the different roll correcting/reduction methods used would be interesting.
These videos are great 👍
Very entertaining video Watched the whole thing :)
Brilliant,had to subscribe
Your videos are very good
Subbed 👍🏻 great stuff
yes more details will be better, more info for us, more video's for you
I got an rc chinook for christmas ages ago and i can remember how hard it was too fly
Very nice video!
i understand this is a old video, but good work on the build, i been wanting to build one of this helicopters just with a bigger scale!
Hi Tom, now this is very awesome! I've done several project with cars and Arduino, also I'm into 3D-printing. I'm very enthusiastic by this video. Maybe I'll try such a project myself some later time. I just have rebuilt my garage for more hobby space. I subscribed and will be following you around! Cheers! (btw we are very fan of the UK, haven't been there for more than two years due to covid-19)
Nice Tom, nice
Great series! Would you mind providing some details ( maybe a video) of your configuration in betaflight? Thanks!
Another good one! I've watched and liked nearly all your videos in a short space of time (you're welcome) one thing that has became painfully obvious by now is that you go to incredible lengths to avoid a conventional swashplate head at all costs without saying so. You create more problems than you solve by not sticking with what's proven sometimes, although I applaud your innovative thinking, until you can improve on the tried and tested why not benefit from the hard work others have done before you.
8:20 the right motor tilted on its own.
It seems that when the PID gains are too high, the motors tilt when spun up on the ground. I think the vibration causes it to drift and it doesn't self centre because it's 'fighting' the ground. Thanks!
I would like to see a one motor collective pitch quad sorted out with quality heli tail parts, and some sort of diy home gamer fc.
While interesting, it would be pointless unless the motor is an internal combustion (or turbine) engine... and no one is likely to bother with that anymore for an uncrewed vehicle.
@@brianb-p6586 why do you think that?
The stingray from Curtis youngblood was fantastic, in all aspects. I think it's price kept people away, and really the cost was mostly his home brew FC. The parts are relatively cheap, easy to service, 1 motor 1esc, it's a no brainier to me.
@@MoralConflict One motor speed controller plus four servos doesn't seem like an electronic advantage over just four motor speed controllers, especially since that one motor controller needs to handle almost four times as much power as each the four controllers of a conventional quadcopter needs to handle. Perhaps the price of tiny speed controllers doesn't depend much on power capability; I'm usually thinking of much larger components (automotive size), in which power determines cost.
Of course the big difference is mechanical, with the central motor approach having four variable-pitch rotors and their control linkages, plus power transmission by shaft or belt to all four rotors; this is in contrast to... nothing required at all (or just a reduction drive at each rotor, depending on motor choice).
@@MoralConflict I had never heard of the Stingray, so I had a look. Nice, but lots of mechanical parts apparently including long drive belts that require tension adjustment.
Really cool build bruh! That is something I would like to do as well! Looks like the height of the motor mounts and the size of those motors and the tippyness of the motor mounts might be more than the PID controller can smooth out - IO am super interested to see you progress!Did you jump through a bunch of hoops to get Betaflight to flash to your Raceflight FC? Is all the BiCopter setup stuff just built into Betaflight?
Awesome. Would be great to go over how u adjust ur pid values to dial it in.
Thanks
