I believe it's widely understood that hardly anyone in "HO" slot cars race the original Aurora AFX chassis. I believe it is a viable alternative for those who love T-jet race'n. They are cheap and plentiful, use the pancake motor, and no traction magnets. Also they are easy to make go VERY fast and require little maintainence. We usually don't have the race-time to dedicate to AFX, but we do occasionally and the are lots of fun, very much like the 'ol jets, just faster. Brass fronts and sponge tires really smooth'em out too. If there were no more NOS T-jets (or they get too much more expensive), I would chose AFX over the AW/JL chassis. I've been meaning to try and slow the AFX chassis down (more too the t-jet speeds us old guys like) by removing the pan/dish that the pickup shoe spring sits in. I think that would make it handle and feel more like a jet than a AFX. Has anybody already tried that out there?
