xmod motors

No an Xmods car is a radio shack car so I am about 100% sure that the only place to buy them is at radio shack

try www.atomicmods.com i hooked up my xmod from there they're awsome they have fast shippings and awesome parts

Go pull out that old Crest Spinbrush that you've got laying under your bathroom sink that you don't use anymore, and pull out the motor from that. (and if you don't have one, go buy one and take the motor out of it.)
That little Spinbrush motor will smoke any motor you'll find in the RadioShack motor packs. It has more low end than the torquiest motor and more rpms than the highest speed motor. I forget what the gear is, but gear it with the highest or second to highest gear that RS gives you.
Woops, almost forgot: to switch motors you'll need a pinion puller. You can get them for about $10.
Combine that motor with the 4wd and you're rockin. Without th 4wd you're spinnin lol.

i already made the spinbrush hybrid converion, and also got the awd, but i have found a torquier motor, but it drains the batteries too much, i am using ic-3s 800mah anda 15min charger, do you think i can get a pinion puller at a local plumbing/electric store?

Nope, I really doubt it. Call them before you go to make sure. Call the LHS's around you, they'll probably have one.

Crest Spinbrush!

A toothbrush motor in a R/C! I used rechargable drill and vaccum motors in larger electric cars,but a toothbrush.

I'll get that Spinbrush just to take out the motor.Must be a low turn motor since its running on a very low voltage in the Spinbrush and has to spin at high RPM.
