Yea it would be nice, but it is easyer with a two stroke to keep all the model airplane stuff inside where it does not show. (I am Scale Dail).
I also wanted to use what I already have. And a .40FP is what I already have. It would be a real trick to keep a four stroke exhaust ALL INSIDE! This bird may be small but I want it to look very very nice without a big pipe sticking out the side.
Still peeling covering! I ordered a roll of silver 21 Century film, to recover the control surfaces.
