revo wont track straight

[a dawg]

i can't keep my revo to keep the same line. i was testing on icy roads but i normally can keep it straight. it feels like one wheel is slower than the other. when i give it throttle it just wants to do 360s. i tried to go wide open out of my garage to see it it was just the roads but it still pulled to the side. the truck keeps the same line when it is in reverse. what can it be?

How much have you run it?
Could be something as simple as a piece of gravel holding back a drive shaft.
Take all 4 wheels off, and rotate you shafts to see which one is tight. It might be a bearing going bad and locking up.

That might be why.

or maybe your trim is off.

it must be the ice, but i never had as much trouble keeping it straight, actully i can keep it straight. it rolls fine, i gave it a good push and it rolled across my garage. i better just practice and get used to not having traction.

I got the impression that it still pulled when running in the garage. Do you mean it went out of the garage straight and then started pulling when it hit ice?
If anything is even slightly different on one wheel, such as a tighter bearing, it probably won't be noticable on dry surface, but will be extreme on ice.

i figured out why it would stay straight. my front diff went out and i wasn't used to driving in rear wheel drive. i'll fix the front diff tomorrow and i think that will fix the problem.
