I’ve had this problem before and still can’t tell what I should do.
When I’m using a high power battery like a 5S or 6S it’s impossible to control the aircraft, I’ve done already a VTOL aircraft and managed to fly it and even make a transition to forward flight but with many problems (spins out of control during transition).
This time I decided to create a test frame just for the sake of saving my planes, and test the VTOL firmware specially the power or thrust problem I’m having. I was playing with parameters like Q_M_SPIN_MIN, Q_M_SPIN_ARM, and Q_M_THST_EXPO but as you can see in the video the aircraft takes off really violently, for sure in a VTOL plane with the extra weight it’ll be more stable, but I’ve tried that before and the same happens, I’m not sure what parameter to change, I haven’t been able to move on to other settings like PID tuning because of it. Also, I never feel that I have enough YAW authority, and I think that’s a problem when doing the transitions, and it starts to spin. I would appreciate all the help from this community.
In the video you can see how the throttle never got close to even 30% and it shoots to the sky, also I’m using Q_stabilize
Some time ago I had good results with a 3S battery, but the Idea here is that no matter what battery we use we still have control.
