I am making a tiny helicopter and was going to use a 3 channel receiver and connect the tail rotor to the same esc in parralel to the lift motor but will it work and do i need yaw control. Altitude will be throttle controlled and i am tipping the main rotor.
If the amount of torque from the main rotor matches the thrust from the rear rotor then it would be stable. I doubt that though. Also without separate control of the tail rotor you will not have any control of yaw.
