you will enjoy the features of the new Evolution

Engine’s NX Series Helicopter Engine.
The Evolution NX Helicopter Engine is designed to be

The Evolution NX Helicopter Engine features a
piston/liner made of a unique combination of ABC

experience flying a model helicopter, it is highly
recommended that you have the help of an
experienced modeler during the first few flights.
Your local hobby shop or flying club can put you
