Zenoah G38
I bought this older Zenoah G38 two stroke rc plane engine on rcgroups.com from a guy in Memphis, Tennessee. The propeller is an 18x8 and the fuel is mixed 40:1. It runs a magneto ignition, so you don't need a battery or an ignition box. It sounds like it won't need much tuning. I have been running this engine on my Graupner Taxi 2400 and it runs great. It has plenty of power to pull a 18 lb. airplane around.
