A stunning engine with solid performance and reliability–the 7-cylinder 77cc 4-stroke glow radial engine is designed for larger models, specifically scale applications where the use of a radial engine in a round cowl will provide the ultimate scale look for the modeler’s plane. While providing great looks and sound, it also delivers the dependability and performance of Evolution.
