how fast is my xmod
 

i have the stage two blue motor in and 6 cells?
now how fast would it be with the fet upgrade?

You wont really see too big of a boost in overall speed with NiMH batteries, with a six cell I would say maybe a decent boost in speed and torque. But if you really want to see a very big improvment I would recommend the Li-ion's which require newer FET's, with those batteries they will use the new FET's at the level they were ment to be used.

ok mr know it all, li ions dont require FET's... wtf are u thinking?! motors require fet's, because the stock fet's will allow u to use a 2.5 amp motor, and with that u cant run a hot motor, u can get FET mods threw me for 25 shipped, and a RTR lithium kit for 45 shipped, the only how ud need something else with lithiums is if ur running more than 2 cells,
which is a regulator, which allows 5 volts to the electronics and all the rest to the motor, if u need anything im on aim at, backdr1ft copy and paste that into a message and hit me up! glad i can help..
