Just FYI, this is the World Models version. I think it would be marginal with the Enya 80, unless you flew at full power a lot.
Oh, mine is a little smaller, my seven year old grandson wouldn't look that big next to mine. The box doesn't say who makes mine, a lack of pride showing :^( but it says a 60~70 4 stroke. I guess when you make a copy of a scale plane they should all look alike :^) I had a WM Miget Mustang, and it was much higher quality than the Chipmunk I've got.
