yeah, mine seems to turn sharply too.

on some surfaces it turns a little too tightly so i have to put harder tires on the front so the front wheels can slip a little.

i guess i should clarify my original post:

when i replaced the 2.2 motor with the 1.6 motor(same car different motors) the car appeared to run faster.

when i replaced the 2.2 with the 2.6 motor, the car ran slower.
