I've always had problems with my Gp42 that came with my Tiger Trainer. It lastes less than a year. It overheats like crazy, and grime got all over it from somewhere (Yah, i diss it, but i bet it was just me being a newbie). Anywho, i busted the muffler off. Would a TowerHobbies muffler fit it? I just ordered an Uproar, and i kind of want to test out the GP again in it, but cant do that without a muffler!
