I have a quadri copter , in according to istruction for build I assembly the propeller with engine :
2-engine and propeller rotate at CW with appropriate propeller direction
2-engine and propeller rotate at CCW with appropriate propeller direction
The engine have a support to connect the engine with the propeller , It's a screw with a Nut. The problem is when the motor rotates in CCW the support has a nut to CW but when the another 2 motors rotate in CW the support of connect propeller has a nut to CW and in many acceleration of engine the nut screw off !!
How resolve this problem?
PS: The engine are turnigy D3530/14
