stage 2....holy smokes
 

i just put in the stage 2 drag motor and took my car for a spin. on my carpet if i turned real sharp the car would flip over. BIG BIG improvement from stage one. i also noticed that my stock motor and my friends stock motor were different. i had the white (drift motor) and he had the blue. we both had skylines and his was faster...weird that they even put diff. motors in the stock cars!

The performance difference could be as simple as manufacturing tolerances and break in. Some of the XMods motors perform much better than others. I have measured almost 2000 RPMs difference between the stage 2 motors that I have.

yep if you like that throw you 2 more cells in ther the fun factor goes wayyyy up but invest in a tube of super glue for your tires the will go flying if your not careful

where is everyone getting the 2 AAA battery holders? my RS only has 3 & 4 cell holders.
