An RCMC with work in any engine with a DC motor that it will fit in. It just won't necessarly run at the same speed as other Legacy engines. If you are not going to add additional smoke effects you would be better off with an RCDR (radio board) and BEMC (back emf motor driver) which don't require dealing with adding a tach sensor to the motor.
If wanted specific smoke effects like blow down you would want to order one for an engine that already has that features. Features are programed at the factory just like the speed curve.
