I picked up one a couple years back. I converted it to lipo, brushless and put in a new set of bearings. Set it up for VTA and TQ'd the car. If you want to update, I'd get a brushless ESC and motor combo along with a lipo just for the voltage cutoff built into almost every current ESC. If you want to stay cheap, a stick pack will work fine until you upgrade. Those TC3s are truly great cars.

yeah i've been looking into a brushless setup. had a custom brushless hpi wheely king, that things was fast lol. if i stay with a brushed motor how many turns? the trinity copperhead that's in it now is a 27 turn, was thinking maybe a 17 or 19 turn

Either would be fine for just having fun. I purposely went looking for one for my son for VTA. They are actually very durable.

1) I have the composite plastic shocks, which I've installed the VCS2 upgrade kit on, and I am using a rear shock tower on the front per the more modern TC3 setup sheets.

I'm running into an issue where the shocks are just too long, especially on the front. I had to shim the front shock tower up 3mm AND take the uptravel limiters off the shock shaft (the VCS2 kit says these are required to prevent the piston from hitting the bladder) just to get enough uptravel to be able to push the chassis of the car flat to the ground. I had to remove the uptravel limiters on the rear as well. The pistons don't seem to hit the bladders, but the uptravel is still quite limited because the shocks don't compress short enough (the bottom spring retainer hits the bottom of the shock body and that's the shortest they can get).

Do the aluminum/factory/FT shock bodies compress shorter, or are they the same?

2) any tips on being able to run the diffs looser than the manual setting without having them slip obnoxiously? They are extremely tight compared to what I"m used to on other more modern TC chassis, and even when they are tight they slip.
Did you try to put washers under the piston, inside the shock body? I have changed the front tower lately and have no problem with shock lengh. You need to run the shocks fairly straight now.

here is a pic of my newly rebuilt chassis with Lipo and brushless

In my TC3 I run a 77T spur and a 47T pinion in 64P mated to a Losi Xcelorin 17.5 motor and a Team Wave RB-30 speed control with no boost.

4.09 fdr is 13.5t gearing for some, unless your track is small ... Most run 3.5fdr in 17.5t.....

Cool

It always seems like tc3/tc4 racers tend to undergear their cars, compared to belt cars, why ??? I tend to overgear my tc4s , and don't get much motor heat .....

It really depends on the motor and timing for the class rules. In VTA I geared my 21.5s between 4.0 and 5.0. My 25.5 is starting out at 3.9 and running cool. Both were no timing. My Losi is geared at 3.9 with a 17.5 and I like the torque of the motor and the temps after a full run. In boosted, the same motor ran between 5.5 and 6.5 FDR for 17.5. The motor revved a ton more as the timing came in. Again temps for either config never went over 160.

It depends on make, track size and what speedo you are using, so far my LRP X12 is geared at 7.50 with fan on.

SteveM , you run a protoform body or something else ? MazdaSpeed6 is the body to have on top of the 3.5fdr !!!!!

Im running an FDR of 4.22 on my Blinky 17.5 setup. D3 17.5 turned all the way up on an LRP SXX Stock Spec in blinky mode with a 50c 5000mah Protek pack. I'm pulling off after 6 mins at 180-190 though. I need to get a fan on my motor
