Roto engines are manufactured by one of the leading Czech model engine companys. No expense has been spared with any of the materials and components used to produce this range of quality high performance petrol engines. Roto motors use a rotary valve induction system to aid easy starting and produce a smooth consistent linear performance with a slow idle speed. Roto is one of the only petrol engine manufactures to use a conventional model type engine mounting system on the 25 and 35 size engines which, of course, allows easy installation into most aircraft. Also worthy of note is the fully shielded electronic ignition system which ensures no interference with your transmitter signal.
