I upgraded a 3rd Rail 3751 to PS3. The engine works great. Understand that you will likely have to file an opening for the tether as well as modify the pocket on the engine to place the tether receiver. It has been awhile, so I don't recall the specifics but it would be easy to provide photos if you wish.
