This is the motor I run, I love the damn thing. It's bullet proof, and adds about 5mph to the topspeed of your buggy compared to stock. It starts way easier than the stock motor too (one time I let the thing sit (without after-run in it, i forgot) for 2 years, it started the first try). After 4 years total of having nothing but nitro in it, the bearings aren't even rusted, it's in perfect condition. http://www2.towerhobbies.com/cgi-bin...?&I=LXBZ33&P=0


Odds are your buggy went wild because of that ****ty battery holder that came with the buggy. I have had that happen to me 4 times now. 2 cars, and 2 fences have stopped my buggy at full speed. It never occured to me that a crappy plastic battery holder bouncing around inside a metal car could have a crack in the wiring and have continuity at slower speeds, then after some jarring at high speed lose that continuity. 4 years later I have dragged my buggy back out and am in the process of soldering up solid nicd battery packs. I suggest you do the same.
