I do have one of the new 172 kits, and it has a lovely engine (but then of course I'd like to keep it for the 172 kit. And, the 172 engine is considerably larger. I'll look at it- maybe I can make a mold and cast a duplicate if it will fit. I've been thinking, if I have to do a big mod on the kit engine maybe I'll just do the fins on the head area.
Also intending to cut out the doors to display theCub with the door/hatch open. Looks like a tricky cutting job.
