Here is an unfinished, Robert Best, 5/16 scale Maytag 72 engine with most all the pieces to make it go. It is rough casted and will need to be drilled, taped and parts fitted/machined with a live axle so the flywheel can turn. It is powered by a rubber o-ring around the flywheel inner hub and runs on a small motor and a D battery mounted in a base that you would have to design and make. The outer Finnish can be filed and sanded for the paint preparation. C...heck out our other items and good luck!
