Can someone please confirm that so called standard T-jet rear axles are compatible with AFX non-mag and MagnaTraction chassis? Searching here and elsewhere indicates that they are but I can't find a definitive answer.
I pack-rat the short T-Jet axles , If you want to use the Vincent wheels you need the shorter axles, or cut the AFX ones down. On a side note I recently purchased some JelClaw Tyco 440 FRONT tires for the REAR of some Fray-Illegal T-Jets I built, they fit the Vincent wheels and come out at about .405" mounted which is close to the original T-Jet diam. They also fit the old aluminum thread on AJ rims without the flanges, replacing the rotted spongies. Cheap, less then $2 a pair. I built 4 economy "Can Am" style cars using Mustang, Camaro and Firebird bodies. solid rivit chassis, JL magnets, Mean Green 6 ohm arms from old AFX's, Wizzard brushes, silver pick-ups, Vincent wheels and the Jel 440 front tires on the rears. I used the small pinion gear because I have a ton of corners. They FLY and FLY OFF. The only problem I've noticed is the lack of "slide" or coast through the corners that the stock magnet cars have so you have to keep the power on while cornering. They really slow down when off the trigger. When they wreck its in spectacular fashion.
What you need is a controller with a coast control, those are made for inline magnet cars and the control is about 100 ohms. For a pancake car I expect that a 200 ohm control would be better. You need for the car to see a tiny voltage when the controller is in the brake position.
