"Yes, it can be done but it’s not easy.
I have three SAB Goblin 770/Urukay’s (800 blades) running the Zenoah RC car engine. Vibration dampening of the Pixhawk FC is one of the biggest hurdles to overcome.
As Nate has said: Safety is a huge concern…"
"Hi Rob,
I noticed a strange offset during setting up the collective pitch. Following your new video setup. SV_MAN=2/3/4. and pitch -5/0/+10 all works fine.
Then with SV_MAN=0 and in Stabilize mode my pitch range is now -6/0/+9
I'm not sure why the…"
I had the same issue as Chris M in that I could not takeoff in Loiter. In this graph, hover at the start then landed, tried to takeoff in Loiter at 380 then gave up at 385, poor skid's took a hammering going full negative at 100%…"
"Hi Rob,
I've had some success with my Pixhawk vibration dampening mount using some mass. With one RX battery attached underneath, I'm getting lower vibration numbers than before. Is this graph similar to your Gas heli?
"@Chris
The errors that trip the PreArm:Check heli parameters are:
RSC_CRITICAL too largeRSC_MODE invalidRUNUP_TIME too smallRSC_IDLE too largefor example, RSC_IDLE must be less than RSC_CRITICAL
For me, I had RSC_CRITICAL and RSC_IDLE the same…"
"@Gary, correct, I was just being lazy with my word’s and should have said alternator.
@Rob, no worries, just want to help in any way I can.
I agree that I shouldn’t be able to start the motor, but in AC3.2 I couldn’t get Ch8 to work for throttle.…"
"Thanks Rob,
That’s roughly what I thought (not for Heli’s) and just wanted to make sure I wasn’t missing something. The gas motor code sounds good, can’t wait to try it!
The Engine-Run-Enable Auxiliary function is a great idea, please add it. It…"
"Hi Rob,
I am just about to finished building my next Gas heli. :)
Can you explain how the E-stop and Interlock in AC3.3 might work for Gas/Nitro heli’s please?
At the moment I’m running the engine kill switch through RC10 Aux, which is not the best…"
