Chuan Qi V12 Model Engine Combo | MCU - Stock allocated for this sale, ready to ship from the factory!
First working miniature V12 model engine and its 4-speed transmission including fully functioning Diaphragm Clutch.
Included with each engine is a high quality metal and glass fuel tank with in/out ports. The MCU model features one MCU unit (motor control unit) to control individual coils for each cylinder vs. two high voltage ignition modules/distributors. This engine does not produce a strong electromagnetic field thus eliminating the potential need to add an electromagnetic shielding or braided steel loom to the ignition system if you wish to install the engine into an RC vehicle.
