Rth nearly killed my plane on its maiden! Accidentally flicked autopilot switch and as soon as it took off plane went rocking side to side and tried to climb immediately. Luckily I managed to jus bring it down on one of its rocks to the side and it only broke prop..lesson to check autopilot switch

I'd be interested in what you find out. I'm having a little difficulty with RTH on my wing as well. There's an added complexity on mine since I have FY-20 doing the mixing (I use this for easy hand launches). My Tx is set to not mix and neither is DOSD. This morning I turned on RTH and it went inverted, almost losing control. |

So generally you leave the aprotgain and aprocgain settings as default and mainly adjust the rocstepgain and rotstepgain settings?? |

the servos controlled by DOSD on your plane and the receiver are joined together electrically by the PPM cable and/or RSSI cable. power for these is coming from your ESC BEC or standalone BEC. DOSD does not supply power to servos

Yes good to know. But why did the servoes start to make sound then? Like a humming sound if you know what i mean.

Well assuming that they aren't some special kind of singing servo and there is no power going to them, my guess would be that you may have wired something up incorrectly?

You're plane should be more than stable enough. You shouldn't need much step gain for it. The fact you said it was bouncing back and forth and tried to flip over is exactly what to much step gain will do. |

Like Mike said...the PWM rail power should be coming from your 5v BEC/UBEC/flight pack. Most likely you've got the 5v line going to your Rx, then it's passed to the DOSD PWM pins via the PPM cable. As for the humming...probably just the servos hunting around center. If you get the UHF antenna to close to the Rx antenna you could 'swamp' the Rx and get some channel cross over which will cause servo jitters. Moving your Tx away from the Rx should fix that. There is normally some servo noise anyway.
