baleisen,
A simple mod really, all I did was take out the receiver cord slack from under the PCB board.
Good news! My Zcar is alive again! Looks like it originally died because the cable to the motor got pinched.
A little soldering, along with a solid gauge receiver cord mod, and the Z is back in order!
Of course now that I've been running a 3.8 motors for awhile (that I got from right here at TinyRC), it's like goin from shootin up PURE CRACK down to Nutri-sweet.
