Twin electric motors

[makem&breakem]

HI all I have just been told about reversing one engine rotation on a twin plane but got no details how this is done yes I can swop the ESC leads but what about the prop, do you reverse it or fit a pusher this one is new to me thanks in advance, sunny Spain.

The prop will need to be reverse pitch.

For a twin-engine aircraft, it is better to buy motors of different rotations and propellers (for quadrocopters).

For the prop, yes, you need a reverse prop.

For the motor, most any motor can be run either way, but they make motors with the threads going CW (for standard CCW spinning props) or with the threads doing CCW (for reverse CW spinning props). If you don’t have the reverse threaded motor, you can tighten it harder and/or use thread locker.

I've always used this article to help program differential thrust. While I don't have a DX9 radio, it's pretty close.

Many props are sold with CW and CCW versions.
The same electric motor can drive either if it is reversed BUT most prop drivers are set for conventional CCW props so if you fit a CW prop and reverse the motor the prop nit will no longer be self tightening. You either have to fit a stiff nut or a second locking nut.

A normal CCW prop in a pusher with the motor direction reversed. I lost the prop when it only had one nut!
