I remember a guy had a couple 40 Telemasters and he put a old style Saito 50 on one. It was really nice for that last flight of the day.

I bought a new Telemaster 40 ARF electric at the hobby shop for $100 and busted the electric motor mount and battery rack out of it. They came out clean. I put a Saito 56 in it but have not flown it yet.
