hello,I build a quadrotor.

I would like my black propeller changes orientation ((front, rear) and (left, right) with two servo controls. When I made the motor does not work.

How to solve this problem? thank you for your help

Very hard to tell without the actual model, so try to upload that and we can have a look how your joint connections are set up.

Ah the problem is you connected the servos to the same group, so they are each trying pull it in their direction while the other one holds them back.

Best rule of thumb is have one movable group for each joint, added the fixed example.

Thank you very much for your help. I wonder if having two different angles are not going to have a conséquance the control. I'll test it. Thank you very much for your quick help.
