ZDZ 112B2RV-J Champion

Already well known for its smooth run and awesome power to weight ratio two stroke 112ccm opposed twin cylinder model gas engine with processor controlled ignition. Now fully CNC made crankcase and backplate out of 7075 aluminium alloy. Weight increased compared to former 112B2RV-J is only 50 grams. 

Engine is based on well proven very power full "RV-J" concept. It brings awesome power, super lightweight and same time very durable and reliable powerhouse. Its run and very fast transitions  are superior smooth with lowest level of vibrations you could imagine.

Fuel intake of this engine is managed by rotary valve which contrary to the usual reed valve system allows much more precise control over the timing and same time brings much longer lifetime without need to change reed valves.
