Okay in theory of course, could the ArduPilot fly a full scale helicopter?
Instead of servos, you could talk to the existing fly by wire of a helicopter (which then move the mechanical linkages). There would be no need to change any code or outputs (because it is just going to the Flight Control Computer). I cannot think of any reason the APM couldn't fly on it, unless there is something to do with the inertia and mass of such a large helicopter causing the code to go to extremes that it shuts down.
Any comments? Ideas? haha just play it as a 'What if' scenario
Haha yeah I doubt the $20 IMUs here are quite up to Millitery Standard 1553b which requires a shit-ton of failsafes and dual redundancy capabilities.
But I was thinking (on behalf of my job at an engineering company) of putting an IMU on one of the parts, and then sending that data to an appropriate flight control computer. Haha just wanted to see what people thought about scaling up these things
Okay, on a serious note.
When you say beef up the PWM output that means increase the signal strength to the servo (in this case full blown engines) or beef up everything in general?
you can already buy autopilot servos that are man enough to fly full-size aircraft (see www.dynonavionics.com and http://www.trutrakap.com/. As far as I understand some of them can still take the standard RC-style PPM inputs.
Having said that, even on light aircraft they are only really powerful enough for flight stabilisation (autopilot duties) rather than full-deflection flight control.
Without faults occuring and a powerful enough means to move the control surfaces (or the control surface controls) it should be possible once you mount the hardware correctly.
Although APM is basic controls only on aircraft from the basecode so flaps and any other fullsize additions would need to be coded in. I would presume the helicopter is the same and needs a couple of extra things added to be fully up on control (never flown a helicopter).
If you had the money for a light aircraft and wanted a ridiculous publicity stunt you could risk your life and your aircraft for that one perfect run.
The APM IS a fly-by-wire computer!
Back to my statement then. . . What's saying the APM couldn't talk to the flight controls of any FBW system?
lol I want an RC F-16C. No a real F-16 with a Rx/Tx on it :) :)
Now that would be a show stoper
Yes the Sgt is correct. If you the helicopter is Fly by wire rather than mechnical linkages with some hacking you could use it much more easily :D
