I don't know if this is a bug or not, but this phenomenon is very distressing to me. When I start the motor, the propeller will continue to shake violently, which will lead to an explosion. This phenomenon has affected my production of propeller aircraft .
I haven't been able to get this to happen with this craft, in fact, the propeller rotates really slow and can hardly generate any thrust, have you reported this bug while using the craft at fault?.
