Devil,

I'm about to start my own Yellow spit. Already figured I'd junk the supplied stab and build a new one. I have a Bison Evolution 52cc on back order. comparing the technical drawing to the fuse, it will fit w/o modifications (except to the firewall) I plan to use the scale carb intake for air inlet, and duct exits to the radiator outlets in the wing as well as using the scale exhaust for air extraction, aside from a couple that I will use for the engine exhaust. Good luck!
