Brilliant - great to see another totally original idea taking shape! Before winter comes along requesting another multi-cam scenic flight in the chAIR, I am sure many of us miss seeing that wonderful machine in action!
I was also taught to set tail rotor gains high until oscillation when flying helicopters. But then certain new manoeuvers can cause it to oscillate. You would have to keep dialing it down until no maneuvers caused oscillation.
The Hiller VZ-1 Pawnee coax flying platform was apparently very easy to fly using just your feet- it became much harder if you held on to the handle bars . So if you lose all your flight controllers just stand up !!
This is great! I've always wondered how well this Coax-Setup would work with 4 small quadcopter-like rotors on the outside. They have a lot of control, since they're nice far out from the center and they can act as a failsafe for the main rotor and possibly hover the vehicle at max power.
Finally, Welcome back! It is so good to see that you have posted (and such an interesting one) a new video, I missed your inventiveness! I hope you are keeping safe and well. Tony from Western Australia 🇦🇺
Awesome project! (as usual) I love how you walk us through the problem solving and show the crashes. Just curious: Any plans for a DIY Sherp update? I'd love to see you take it on some rocks and off-road. Push the limits of those tires.
Perhaps lower prop has to throttle a bit higher, which gives slight gyroscopic procession, so when stopping laterally, the pendulum effect causes slight procession due to higher bottom inertial and prop speed. Just a guess though. Incredible build though, great design, I really like it.
Nice work. I'd put a shroud around it as you are losing a lot of power and control as air is pushed out the sides. I'd also put the weight on the bottom with the control vanes on the top.
looks like a dart it will always orient itself to point into the wind, even if the surfaces above and below the cg are the same size the just is a lot less resistance in that direction, than being hit from the side equal drag from all sides would probably be preferable, but where would the propellers draw air from...
It would be nice if you did a video explaining the downsides of your quadcopter design. Talking about the stress on the metal. I saw some news or forum where you had briefly mentioned that.
What if you made it more efficient and controllable by combining the rotor blades which provide the lift with the adjustable vanes which control direction? It would be a real breakthrough.... Oh wait, that's a helicopter.
How many lbs of thrust are you getting with the dual rotor setup? Can you stack motors and get double the thrust? I’m also planning on building a hang on to or sit under type prop bar using brushless Tiger motors U15 ll 80kw motor. Which is rated for 80lbs thrust a piece. I want to use for houseboat to fly from houseboat to shore.
