This new 40cc gas engine was developed in collaboration between Valley View RC and Quzhou Jjinnuo Machinery Co.,Ltd. After several design changes and many hours of testing I feel we have developed the only twin cylinder engine that will fit most 30cc airplanes and will also fit inside a 30cc airplane cowl. The distance between spark plug caps is 7-7/8". The use of a smaller 1/4 X 32 spark plug and angling the plug in the cylinder makes this possible. The use of an Rcexl ignition on both engines makes these engines very reliable and will last for many years.

Includes: Rcexl ignition, spark plugs, mufflers, stand-offs, long throttle arm, mounting template and manual.
