I have a total of 10 AW T-jets. 5 are the older version with no magnet. I examined all the cars for gear tolerance etc. I put 6-volts to test all the cars, and then selected the smoothest running chassis with the least motor vibration and best tolerances.

I recently set up a drag race test track with 12-volts. I oiled up the chassis, etc. The best car from the lot screamed like the gears were going to come flying out of the chassis. So I threw the other cars on to test them. They made even more noise! Ouch.

I tested the stock Micro Scalex cars and they are all bullets! The AFX cars also run great!

Had I bought these T-jet cars from a store. I would be taking them all back for a exchange or refund. What an eye opener.

The plastic idler gear flops around like a dead fish on all 10-cars. These chassis are not very good at all.

I tinkered with one chassis for several hours yesterday. The results of doing back to back tests gave one promising run where the gears didn't make noise and the car was much faster. Then the noise instantly came back and the brakes went on.

Can anyone please suggest how to make a stock AW T-jet run smoothly?

Thank you very kindly in advance,
Ken
