Thanks for all the answers. Yes, the chassis is a AW 4gear chassis that came with their Dragster set. I have a very high power magnifing glass, held the chassis up to a bright light and looked through the opening. The brushes "seem" to be making good contact. I even took out the traction magnets. What is it that makes the NOS chassis better? Is it more stiffer? I will take it apart later today and make sure thebrushes are "free floating" and try one more time. If that doesn't get results, I'll look to getting a NOS chassis. OR, has anyone had good luck with the AW cars making them competitive? If so, what was your secret?  |

Hey Charley, I think the AW is a softer plastic. I use it with any class that has ceramic mags with no problems yet. When polys were put in an AW botteming was bad enough to leave groves in t/mag pockets (t/mags were removed).
Another thing might be your armature shaft if you changed arms. Retention ring on bottem of shaft might be rubbing chassis floor. Look between brushes for signs of polishing around shaft hole.

charley all my polymer cars including the unlimited match race for Summer Nationals are AW chassis. I have not had pceng's problem with sagging. Maybe I have just been lucky. The T/F demo dragsters in the Test N Tune were all Auto World. pceng is correct on the arm shaft tazman thought his was loose, it was not. After I took it apart I could see where the shaft was rubbing on bottom of chassis.
