Wicked, I have to learn to stay off the computer. Just got off the phone with Jeff. Needless to say I bought one and should have it early next week. I have a Giant Stinger ARF that I haven't built that is just sitting around downstairs that would make a good testing mule for this engine. By the numbers the engine is getting I am thinking it would go good on a 75cc to 85cc model for IMAC type flying. something like an Aeroworks 33% Extra 260 or a Hanger nine Carden Yak 54. both are around the 20 pound mark. This engine is putting out better numbers than a G62 so I'm thinking it should work OK as I don't fly 3D.
