Matt, I've got a bunch of the JL Tjets...and Xtractions...as well as Tyco 440X2's, AFX original Magnatractions, Tomy Turbo's, and Gplus cars. There's plenty of variety out there....and there's nothing wrong with playing with some of each....as I'm doing.
When I was in Florida for the past few weeks I had about a dozen cars with me to race with.....a Tomy Turbo, 2 Tyco 440X2's, a few vintage AFX Magnatractions, a Gplus, and the rest were JL Tjets. I had fun tweaking each car..... :thumbsup:
As for the JL Tjets, there are some that are great right out of the box.....and some that aren't......and from what I understand some particular released series cars are better than others. Bottom line is I don't own any vintage TJets yet.....so all I run are these JL Tjets.With some minor tweaking with the pickup shoes, changing the tires.....or perhaps aftermarket wheels ,checking wheel clearances,oiling and etc. a stock TJet can run rather well. Another recomendation for you if you're going to run TJets is to add a small round Neodymium magnet to the bottom of the chassis......right where the flat plastic part of the chassis is underneath. Make sure the magnet is mounted inline with the pickup shoe....only one magnet is needed too.......essentially you be able to run at a faster pace...without fear of coming off the track as easily. I just learned this trick while in Florida......and man does it make a difference.
