Hi!

I have got a "new Traxxas Rustler VXL." It runs pretty good. But I have minor issues.

#1. When I give just a little bit of throttle to move the car very slowly, it does not move smoothly. The motor and the gears sputter. But if I give a little more throttle, it does not sputter any more and goes smoothly and faster. Sputtering occurs only when the minimal input of the throttle is applied. (In addition, at this moment, I am running the car with 6-cell (7.2V) Ni-Mh batteries.) Is this normal or not?

#2. When lifting up the car from the ground, over the half throttle, vibration occurs. When taking off the rear wheels, above the half throttle, there is no vibration. But with putting the rear wheels on the car back, over the half throttle, vibration occurs.

Does this mean that the rear wheel are out of the balance? Or is there anything wrong on the drive train? I ran this car only twice for a test run. No jumpings or abuse yet.

If the wheels are out of balance, what is the best way to do balancing? After balancing the wheel, does balancing stay or not?

Your advices will be greatly appreciated!

Thank you very much for your attention!

James
