Home made helicommand

My prototype heli stabilisation system using rate gyros on the elevator and aileron, with mechanical mix trex 450 hde for testing. works on the bench but flight testing will prove it.
It will take some calibrating for best results and the Esky rate gyro's aren't the best around (c:

We'll see how it goes.

does this set up works? i wanted the same thing because i cannot install other stabilization system wont work with me since I fly near buildings...I don't have an open field to play and install those with sensors

[GaryGraham66]

It should work in theory though I never got around to fully setting it up in flight.

[miozombie]

I see...I have to improvise coz I don't have that much space to fly around except an open parking lot. My hover is unstable albeit when I had my caliber 5 flown by an expert it's just a breeze..so i think nothing is wrong with my heli...there's something wrong with the way I fly it. :)

Get a decent simulator mate it is the best way to learn, you can become too dependant on a helicommand etc and it restricts your learning.

[GaryGraham66]

me thinks testing will be somewhat of a run and hide event (c: should work fine (fingers crossed) not sure how to get it to work on a ccpm heli though. Testing over the next weekend.

The commercial RC "autopilot" systems use and optical sensor to reference the earth's horizon to maintain a positional reference. This system uses inertial and will not correct for the inherent drift (error) .

It may be difficult to control in this fashion.

[GaryGraham66]

Yeah I know but the auto pilot version will not work if there is no horizon, ie near buildings or trees etc. the helicommand system works on gyros and an optical sensor to prevent drift, I'm not taking my laser mouse apart to make one of those. (c;

mmmm i like to see a video on what you have done

[subarooby]

I agree but I have considered doing the same thing just fr laughs, the helicommand works exactly the same way except they spent mega bucks developing PID's and small electronics, trying to come up with your own setup must be near on impossible to get just right but the crude concept is fundamentally the same, be intrested to see this thing fly huh ? and they must be heavy in comparison

[gintaras4bar]

I'm very skeptic about such setup. Flight stabilization requires much more sophisticated PID or similar control, which is impossible to achieve with these cheap gyros alone. I'm electronic devices designer with 25 years experience, so I know very well how these things work.

[rodstartube]

this would stabilize the helicopter, not the position

[wrxsavvy]

this is more like a flybarless system than a helicommand. either way great job!

nice idea!!!!! 5/5
