In the previous video I had problems with twitching motors.
Now it solved. All four motors was short circuit with bolts.
I decided to use 6040 props to fully test my quad before breaking 7040 props. I have 20 pairs of KingKong 6040s so I have a lot of spares in case I brake them.
I also flashed to betaflight 3.2.1 with support of GPS, but its totally useless: Core pnp pro does not read gps and magnetometer from flight controller and you cant see coordinates, speed and altitude on your OSD.
Thats very strange: TBS sell GPS that can be only connected via BST.
But iNav does not support reading GPS and magnetometer from BST.
So you cant use navigation with TBS stack.
I also have problems with video and dont know yet how to solve them.
