Product Details

ORE POWER for 50 cc class aircraft!

The GT60 is everything 50 cc fliers want in a gasoline engine – durable, efficient, easy to operate and high performance. A liner-less cylinder makes the engine light, makes it cool faster and gives better exhaust-scavenging characteristics. Plus, a E-6020 muffler reduces engine noise and directs emissions away from your plane's fuselage.
