im new to drifting. i purchased a traxxas 4 tec during the winter and im going to turn it into a drifter. is there any thing i can do to make it drift better? anything like locking the diffs? what about like pinion and spur gears i could get.

see how it drifts first before you start changing things. Once you do adjust the tightness of your front and rear diffs and go from there.

Yup. Don't change a thing till you know how it handles at first.

my car understeers more than i'd like. whats the cure? XXX-S with ABS

xxx-s is the way to go with a brushless on it and some abs or pvc. Driving becomes smooth while the drive train is protected. i personally didnt think the 4tec was a fantastic drift car but with locked diffs strong servo and a good motor on it it handles much better.

i drift a 4tec also. i have my rear locked the front tight. i run a 87 spur and a 22 pinion, i am running a 6 cell with PVC tires it handles great but i wouldnt mind havening a MM on there that way i could gear it for more sped to help carry the car through the turn

you dont need a mamba to have enough power through a turn. Ive got a 19t komodo dragon, and on plastic type tires i can hang with more powerful brushless motors.
