Two motors, two ESC, different speed

“”Is it possible to run two motors at the same time at different speeds, or with one motor on and one motor off?”” Bob

>YES< can be done.

Two motors, two ESCs, different speed (delta yaw) or
one motor off, the other full on or in-between (adverse yaw, 4D and beyond ).

The good news, this can be accomplished with the ole BCR (Before Computer Radio).
The computer radios MIX / STICK potential add more functionality.

Connect ESC-1/motor-1 to THR CH3 (normal)
Connect ESC-2/motor-2 to RUD CH4 and cut ESC-2 red wire

AT THIS POINT, ‘normal’ rudder servo function is lost.
The GOOD NEWS lighten the model, remove rudder servo and cross couple rudder to aileron like we did back in the ole-days BCR.

AT THIS POINT, the old rudder stick, now NEW THR STICK is spring loaded at half throttle.
I suggest, disable spring / Phillips screwdriver / long nose pliers.

For the more adventurous than me … ...
Do not disable spring, SUB TRIM motor synchronization with ‘trim’ lever.

Computer radios MIX, STICK, EXPONENTIAL and SUBTRM only add sketty-eight more options.
