You Are Bidding On A NIB

YS F-91 AC

Supercharged .91 Four Stroke R/C Aircraft engine

I bought this for a project and never got around to it, never even put it together

needle valve still in package, my lazy is your gain, has all wrenches documents etc.

It still has some of the packing grease on the engine & muffler & wrenches.
