I like speed. On pavement, i like high speed run after run.

I started off with a RC12 pan car, and put a feigao 6S in it and ran 8 cells. It was ferociously fast, but had less then no control, not to mention it needed new tires every time i had to recharge the batteries.

So i sold that and went to a TC4, figured a 4wd sedan should help greatly in terms of straight line acceleration and driving. It seemed to work out very well. It was extremely controllable.

Well i hadn't played with this one for a year, and i charged her up and put her down and cannot get it to go straight for more then 15 feet! LOL!

I'm using "venom magnetics" premounted tires on it (brand new) and i don't know if its something i'm doing wrong, if these tires are no good, or what my problem is.

Does anybody have any recommendations for a good tire combination and what i can do to keep this thing on the road?

Thanks in advance

is your steering trim centered?
those tires arent the best also.

yeah i'm kinda thinkin that these are some cheapo tires!

The steering trim is straight. even if i get the car rolling slow and add a little accelleration, its fine. When i punch it, it doesn't go anywhere, it just spins out

try tightening your front diff a bit ( if you use one).

What about toe-in? Pointing out in the front, and pointing in at the rear?

Rear toe in is factory 3 deg. Front is closer to being sraight then anything.

I just went through the manual and put all the adjustments back to the factory defaults. The two right side wheels shattered half way around the bead and are now useless. I'm gonna wait until i can get to the LHS to get some new tires

I asked the opinion of my local hobby shop owner. He seems to feel that ambient/ground temperature makes a large difference. It seemed clear to me i just hadn't thought about it, but it was 37-40F degrees that day. I have a feeling that played a huge role in my problems.

He also mentioned he didn't think the venom premounted tires were all that bad, certianly not the greatest, but not the worst.

Since it was colder out, your rear diff fluid might be thicker which tends to cause the rear to kick out during on-power turns.

Brian, I'm no TC4 guy, but I don't think they have sealed diffs. I think there ball diffs.

That is correct, they are ball diffs. The diffs are pretty tight because all i want is straight away's, not worried about comming out from a corner. I used to be able to punch the throttle from a stand still and it would go perfectly straight and pull like mad all the way to top speed.

I think the cold pavement and cold tires were the biggest culprit. I've dialed the car back to stock (except for shimming the rear suspension for some anti squat), so i'll have to see when it gets a little warmer and i get some new tires on it

Oh well, shows what I know about TC4's. :)
