Hi everyone,
I have a huge problem with my hovering ESCs on a Quadplane. I am using FVT LittleBee 30A ESCs with Quanum MT4108 700kv Motors on 4S. After arming and activating the ESCs by switching to QSTABILIZE they spin up to idle throttle as they should. If I raise the throttle a bit some of the ESCs shut down depending on the aircraft's attitude.
The problem is, that when applying some throttle, some of the PWM values go to Q_THR_MIN_PWM and do not stay above Q_THR_MIN_PWM+Q_THR_MIN. While idling all motors spin constanty at Q_THR_MIN_PWM+Q_THR_MIN.
Does anyone have a solution to this? I have tried to set ARMING_REQUIRE to 2 and Q_THR_MIN_PWM a bit higher, but the ESCs still get Q_THR_MIN_PWM while disarmed. After some thinking this approach wouldn't work anyway, because the aircraft will be armed in fast forward flight. Image may be NSFW.
Clik here to view.In BLHeli I have the PWM values set to 1000-2000. Q_THR_MIN_PWM is set to 990, because the ESCs wouldn't spin up if they get initialized at 1000. I have Q_THR_MIN set to 50, which works fine for idling.
