Will check out parma's ultimate bumper. I had one when I ran a TC4 and it was the similar to xray's hard bumper but was made for the TC4.

You can checkout post #10888 for a list of upgrades possible, and choose the ones you'd like.....

Default TC4 setup for carpet oval ?

Anyone have a good setup for running a TC4 on a carpet oval on foam tires ??

Our club has a "OTC" class (Oval Touring Car) that they run with NASCAR bodies on them.

Thanks !

Thanks for the replies! Overall, are these cars pretty tough? A guy in my club is selling an Xray T4 roller. I think I could talk him down to $300, but even that is more than I want to spend on a car for my kid. I don't think he'd notice the difference in performance between the two and he's certainly not the smoothest driver. The TC4 Club Racer is only $150. It looks like it would be a pretty tough car and easy to setup to be driveable.

If you are not wanting to spend endlessly, then the tc4 is for you , with a parma bumper upgrade and shaved wheel axles.... Xray parts are seriously expensive !

xray parts also break much less often than other companies, and I own an associated tc6. Have driven a tc4 and I know they break and what parts. Personally I'd take the T4. You won't have to buy an upgrade chassis later down the road for your son either.

Yeah. You don't need to tell me! I am racing an AE TC6.1 World's Car. I love it but am always making upgrades and spending money on it! I don't wreck it too much though. The TC4 looks pretty tough. My son will give it regular beatings on the barriers. I'm going to set it up for racing on carpet. 17.5T

For carpet setup, you'll need to lower the roll Center by changing the front arm mounts, with part#31064 &#31065(no shims), and the outer rear arm mount with either the 2°block(#31069) or the 3°block(#31067).... The 2.5°block(#31068) is very hard to get ... These blocks will stop the traction rolling, and give your son a good starting point to get going. Other than that, keep the rear camber at 1° or slightly less , and you won't have to worry about losing the rear.... The blocks are $12 each, and the only supernecessary upgrades to boost Performance and adjustability...

No need to answer that one, I just took the Shields off my drivetrain Bearings only(I put Teflon Bearings on the axles), and WOW , what a difference !!!! That should be mandatory in all tc4's and is #27 down my list of upgrades... No tc6.1 or Xray T4 will ever be that free...EVER...lol....

It would be a HUGE difference. But you will obviously sacrifice longevity. This was an old trick "back in the good old days" when drive train efficiency was paramount due to the motor/battery wars. Nowadays, in my opinion, it's not as necessary but maybe except for the 17.5 "stock" class where there still seems to be a disparity due to battery "C" ratings and some "17.5 stock motors" are more "stock" than others...

To see for yourself, try this. Spin your ball/gear diff in it's housing without it being attached to any other gears. Then, take the bearing shields off of the ball/gear diff, motor spray all of the grease out of it, put light bearing oil in them and reinstall. Now spin them.. voila... they keep spinning with very little resistance...

I think going with Teflon sealed Bearings on all the wheel axle, and unshielded Bearings in the rest of the drivetrain is the way to go if you don't want to get ceramic Bearings all around. Also, the rubber sealed Bearings could be put to good use without the drag of their Shields...

Read pages 7 to 10 or so of the TC3 forum, considerable discussion on removing bearing seals!!!! I was totally bored waiting for "SANTA" and was browsing. Yes Virginia there is a Santa Claus....... I just unpacked my NIB Factory team TC3 kit I Bought on Ebay last week, Yea, I paid enough but it was one of those GOTTA have moments. Also have NIB TC3 Racer kit, at least I got it cheap about a year ago. If any one is interested there is NIB Team TC3 on Ebay right now.....HHHHHHMMMMM. $249.00 buy now or best offer.


NOW....TO build or not!!!!!!!!
