Picco007: Personally, I would recommend the LRP, since its smaller and lighter than the GTB. Personally I run the GTB and remove the fan for clearance. They can pretty much the same things, exept that the LRP has cool throttle settings(1-6) that the GTB doesn't, as well as LIPO support. BUt if you do get the GTB, the get the 4.5R motor, so that you grow with it, and dont have to spend more money on a new motor once you get bored of the 6.5 or 5.5(too slow after a while)...
