It sounds like the mesh on your gears might be to tight. I run a single speed with a 13 tooth clucth bell and my gears has lasted quite awhile. The only gears that I have seen are red I didn't know they made different colors.
Ofna has a 6 cell rechargeable reciever pack with charger for around 20.00 dollars US. Which I recomend if you are running your truck alot, try to get at least an 1100 mah pack I have seen them as high as 1400 and I think Trintiy has just released even higher mah cells (higher the mah the longer the runtime on the pack).
