oss of the drivetrain.
Ha I have a laser tachometer and did 2wd vs 4wd and no difference on a fully ball bearing tamiya hummer. Nananana [sm=tongue_smile.gif]
See how much weight of you finger you need to start to turn the wheel of one locked axle 2wd, then times it by 2. I bet on a good kit with bearings you will barely need any force to get traction.
But there is more stress on the drivetrain on hard acceleration. That's why I don't launch my Saab 9-2x unless there is a riced up fart can next to me but that's a different story..
