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.
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
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.
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).
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 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;)
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. 🙂
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.
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.
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.
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.
@@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
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.
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.
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.
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!
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?
Both rotor shafts are tilted forward as they are in this model. The blades of the real helicopter do need to be synchronized because they overlap, but it's not problem because they are connected by a shaft.
interesting build. you could go with an digital servo (not looked at what you are using) and solder on a 4th cable so you get an feedback from the servo to an rssi or reconfigured current pad. that way you fc always know the servo position and you get better controls. I use that type (Bluebird BMS 210) with an feedback on my tricopters so I could tune all in Betaflight.
Maybe a tip to consider, Make both props turn in the same direction and control the YAW by offsetting the angle of thrust between the two.. this way it will fly smoother IGE because both props' downwash will create vortexes in the same direction,
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.
Someone who is on an extremely tight fixed income budget, but wants to get first 3d printer with the requirement... must print largest possible projects, which 3d printer do you suggest?
First, I guessed you want to create a Chinook with that software controlled helicopter method that you made before :)) I promise it will be very very cooler and more mind blowing 😁 Anyway, I really like your works 👌
Yes mate, I saw that just now. Epic build. Imaginge building a really advanced one that could lift an RC tank just as the real V-22 can lift a real tank. But that's just my geeky head spinning around. I think the V-22 is the coolest aircraft ever because of how complex it is and how badass it looks when flying. Also with a GPS module so that it self hovers.
As most videos are made by people from the USA or Canada where the old system is still used... hearing metric is rare here. And although I am fairly and squarely from the metric era, I still prefer the imperial measure and often defer to units of measure in inches and feet.. lol. I grew up hearing dad use it all the time.
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.
Because of the tight tolerances of the basic frame I would have been tempted to heat the aluminium section in boiling water before assembly. this may have allowed the printed parts to seat better.
I'm not sure if youre aware of this or not, but have you accounted for the gyroscopic precession that will occur when you try to tilt a spinning rotor left or right, it will actually try to tilt fore and aft instead. Now of course your hinges only swing left and right , and I'm sure your servo can "muscle it" left and right with some considerable effort, but wouldn't it be easier to apply the servo arm pressure in a fore and aft plane. But also I see this as a point of stress in the future, with the force of the gyroscope always wanted to bend forward and aft against your struts and hinges. I'm sure some testing would confirm this.
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

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
I love your videos, informative, easy to follow and you articulation is wonderful.

This is one of my favourite subs, great content and a great presenter - down to earth and mild mannered
That high speed hammering was far too enjoyable
Nice hammering together edit. If only it was that quick!
Sweet! Looking awesome already! :D
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

No. Its an E. Not an A. Hard to discribe how it sounds. Look for german Videos with a Porscheeee. Never just Porsch. Greeds

What flight control did you use
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.

maybe a too high or low I (integral) value

I got an rc chinook for christmas ages ago and i can remember how hard it was too fly
It's not that you have to do what's already been done, but you have to do it the hard way.
Great video, Thanks!
Very nice video!
you are a legend man
IMHO adding cyclic pitch (in only one DOF - roll) to each rotor will be more efficient than tilting rotors.
