well for a motor... u want a higher turn. I run a 27turn, and its perfect.
buy some PVC or ABS, and cut them the size of a wheel. Superglue it to the rim for drift tires.
You need a 4WD car.
10 scale electric
for body's... not sure. i run a HPI 350z. anything you think looks good drifting, go with. Now there are 2 types of body's: 190mm and 200mm. Find out wat ur car is and only buy that body.
