Maybe a better question would be-------How many square inches do you have on this plane?
As in frontal area or wing area? Its an 84" wingspan (18"chord) profile 85" long with aproximatly 16-18oz/sqft wing loading (this guess is on the high side...better safe than sorry)
In any case I don't really want to spend much more than $90 on the engine (before conversion)
