I guess I should've been hacked off that GM parts were not interchangeable with my Mustang, after all a small block chevy is cheaper to build than a small block ford.

Ammo is the fuel of guns and fuel is interchangeable between practically all RC engines that use the same type of fuel or caliber of ammo. Outside of an AR-15 hardly any guns parts can interchange. Colts,Uberti,Vaqueros are all different and even 1911 .45s need the right magazine or they won't function properly. Trust me I know.

Hobby doesn't imply that its easy or everyone would be doing it. I like the challenge and the fact that I get to put my ingenuity to work in figuring out a solution. Its good for the kids, they'll learn something. Unlike how some schools give A's for effort and trophies to all the little leauge teams no matter how crappy the work or careless they were.
