I am using the Generic Quad Delta vtol.
I used version 1.8.2 until recently. (At 1.8.2, my plane flew perfectly.)
The upgrade to 1.10.1 was carried out, but there are some problems.
First of all, the multi-copter does not turn off completely even if the air speed is blown into the pitot tube during the indoor test.
Second, there is a continuous beep sound from the rear motor.
(as if ESC wires were not connected to FC)
I went through the ESC calibration perfectly.
Ask for advice.
