I just purchased a super chipmunk with 89'' wing span at a estate sale. Very nice kit build. I don't know the kit. Wish I did.
This gas engine is on it. Aside from the broken fins it's great inside. Took it apart and cleaned since it has been sitting.
Has Mahle in the back of the barrel. Has split crank and needle bearings on the rod. Piston is about 1-3/4'' across the top. Will the broken fins hurt anything.
Does anyone know the make and size.
