I bought a microsizer 2.6 motor from Cellar Dweller, in Winipeg, and am having some "issues" with it... It has almost no torque, and I have to push start my Z-car to get it going. I had to put a piece of paper behind the piece of metal that touches the tab on the motor, and that didn't do much better. This hobby store charged me almost as much as what I bought the car for!
You'd think for 15.00, they'd sell you a GOOD motor!
