Hello,

Recently purchased a few T-Jet Tuff ones. Very strong, but the the problem is the front end "hops" when I accelerate fully, making it run intermittently as it disengages from the rails. Usually results in it coming out of the slot. Fine when running it slowly. Tires? Axles? Any ideas would be greatly appreciated!

you can lessen the spring pressure by cutting little off or heating with a lighter.
you can restrict shoe movement by bending the top of the "window" just enough that the wheels will not leave the track.

Here is an article on tuning T-Jets: https://drive.google.com/file/d/1msYjFT2HVbaSxNC5g_QhEwM8cjBHyDNf/view?usp=sharing
There is a section for pickup shoes and shoe springs. You might check to see if the chassis is not warped so that one front tires does not touch the track. If that is the case handling will be erratic.
