Honestly I love seeing projects like this. I think so often creators want to have something that is totally functional and works perfectly to show instead of showing the design process. It is really helpful to follow your thinking and the process you go through to solve problems. Thanks for sharing this!

[@Matmamtmamtmamtmamtm]

To counter the torque, without needing an additional rotor, you could attempt what the likes of the MD-902 helicopter uses; It still has the rear boom, but along one side it has a rib to reduce the airflow down that side, whilst allowing free-flow along the other side. This creates a difference in pressure, producing a moment; it might be worth a shot, but difficult to see if it'll produce enough of a difference

[@danyalag3366]

@12:17 Its really amazing how the gyroscopic effect of the sway bar kept the propeller stable and producing lift even when it was completely detached from the helicopter.

[@woutmoerman711]

It reminded me of the bottle as a booster rocket lifting that rotor as a separate module.

[@paulmoffett8707]

I love this sort of stuff, splendid work! My immediate idea was the same, to reuse the exhaust from the turbo to counteract rotary action. Humble suggestions; 1. Place the bottle upright to maximise effective rotary thrust. 2. Shorten the turbo exhaust to a minimum and give it a tail. (The tail could be inverted). 3. Chill the bottle whilst pressurising to maximise available air mass over time. (Short launch time required, as the bottle warms from ambient air). 4. Upright launch mechanism would be simpler, in a number of good ways.

[@nolanwaldner]

Yeah, an air-powered 'bicopter' (like the RC Chinook) seems a lot easier to engineer than a dynamically-adjusting tail rotor.

[@briand8090]

@@nolanwaldner Jet tip helicopter could be a better solution than a tandem set-up like a Chinook. No anti-torque needed. Tandem would need equal lift at both rotors to hover. Counter-rotating might work because there's an increase in efficiency on the lower rotor. Still, jet tip rotors are were I would place my money when it comes to a compressed air system.

[@MrBlackHawk888]

You definitely shall already know it by now, but anyway I just would like to remind about possible difficulties with swashplate mechanism.

I like also seeing projects that don't work as planned, because that's just how reality is sometimes. Only seeing the social-media survivorship bias can make one feel incompetent if any project fails, but seeing other people fail too is a nice balance.

[@Skyentific]

Idea: build a kite with control surfaces moved by servos. No propellers, fly just on the wind. You attached it with a single string to the ground, and it should fly by itself (moving these control surfaces). After you can attached small propeller to generate electricity, and either send this power through cable to ground, or to use this power for servos. Btw, great video!!!

[@rakr9334]

Ideas for improvement: - use some pliers-like printed arms to lock the whole heli around the bottle. You could avoid uneven upwards momentum. - insert a tiny valve to stop the rotors running (and vibrating) while pressurizing the air tank. Open the valve remotely with a line. - change the filling valve so that the levers presses the valve away from the heli. -> 1. Start up rotor 2. Stop pressurizing and drop the filling valve 3. Unlock heli

[@TooSlowTube]

Thrust efficiency from a propeller also depends on the pitch, not just the diameter. Pitch is usually given in inches, for model plane propellers - it's the distance the prop theoretically travels in one rotation, in a very idealised situation. As a rule of thumb, a propeller with a ptich of half its diameter (e.g. 8x4 or 6x3) gives the best static thrust. For a prop with more pitch (e.g. 8x6 or 6x5), you get a better top speed, but less static thrust. It's a lot like choosing a gear on a bike, or in a car, then driving in just that one gear.

Turn the bottle vertical to reduce downwards drag, a cylinder is a surprisingly draggy shape. I reccon you could see much improved performance without loads more development.

[@aerospacengineer1]

One thing to note is that you can create a helicopter setup like the CH-47. This was not the first heli with this setup, but it is one of the more successful ones. Why go to this setup. The first reason is that as opposed to having stacked coaxial rotors the dual rotors in this setup will allow you to increase your effective rotor disk area as well as canceling torque. Weight will go up, but you can also carry a larger volume of air. If the bottle size were increased to a 3L bottle, the volume will increase faster than the weight increase. I also have taken these bottles over 120psi over a few cycles and they have worked, so you may be able to increase the stored energy as well, though may need to change the fill method to accommodate the higher pressure. Just some thoughts. It was a really fantastic video to watch, and awesome to see the shock diamonds.

[@StephanAhonen]

You need to move the filling nozzle to directly underneath the center of thrust/mass. Right now, what's happening is, the moment you charge the system enough for thrust-to-weight ratio to exceed 1, you start pitching forward because point where you're holding it down is well forward of the center of thrust. The moment you release the air supply is the moment where you are generating the most thrust you will ever be generating, and because you have to release it when it starts pitching forward, your maximum TWR is only slightly over 1. The moment you release it, the air supply starts running back down and you go below 1 TWR pretty much instantly, which is why your flight ends up so short. Moving the filling nozzle to the center of thrust/mass, or alternatively, using a hold-down method that restrains it from pitching, means you can charge it up as much as you like and release with a TWR much higher than 1.
