What gives ?
I know what your problem is : Your car is understeer all the way.
You can't compare your car with others because they are already have their setups.
Especially the Yokomo guys .... hehe.....

it's understeer esp when taking right hand corner.
btw, i got 6F batt placement. I might be reducing caster block from 4 to 2 sometime next week.

Understeering is caused by to much rear traction...the front has less traction than the rear, causing the car to push into a corner.

If you post your setup people here can help tell you what you need to change to get more turn-in. Setup correctly, the TC3 should have incredible turn in.

i agree w/ tony. if you already have a GREAT turn in, then preload the left rear shock by just a 1/8 to 1/4 turn of the spring collar. i like to check for even on power steering (actually rear traction equality) by trying to do donuts (from a stand still) and tweak the spring collars until turn radius is even. one last test is to make sure the car is steering straight, then punch the throttle (from a stand still also) and see if the car accellerates in a straight line. again, preload the rear on the side the car is arcing towards. if you have to preload so much that your ride height is being effected, take a little out on the opposite side as opposed to preloading the side w/ less traction. b.t.w. i also run a 6f batt setup.

I used to run Yokomo 600wt in front and 400wt in rear. Blue spring all around. I found this setting is still a little bit "push" when entering high speed corners. I rebuilt all shocks by using Yoko 400wt, keep the same spring rate. Hope the car can turn faster next time.

Tony, here's my current setup:

FRONT END:
Red Spring w/ 50wt/ 2 hole piston
Mid hole shock position
4 block caster
2 kickup
0 toe in/out
Stock camber link position
6.5mm ride height
-1 camber

REAR END:
Gold/50wt/ 2 hole pston.
mid hole shock pos.
2 antisquat
-2 toe in
Outer lower camber link pos
-2 camber
6.5mm height
short wheelbase

forward batt pos.
no swaybars attached.
HPI 35r all around with firm inserts.
100% Dual rate
+35 Str EXP

I've tried rear swaybar, it somehow reduced understeer just a little.
Hey Tony, would increasing steering exp help corner better ?

Redsand: Have you tried a softer rear spring or the batteries at the back? I think it will generate more steering. btw, are you using the oneway diff?

And get rid of that positive exp steering. If anything you should have a small percentage of negative exp.

I think i don't agree with you, because softer rear spring means more rear tractions and the result is more understeer or less steering

Daniz is correct, as long as you keep the shock in the same location. If you move the rear shock (top) out, this will give the effect of a slightly stiffer spring, thus, giving more steering. You COULD go one stop down on the rear spring, and move the rear shock out, and this MIGHT give you a slight amount of steering, but I can see a few other things that will be a bit more drastic...

First, on the front, for more turn in:

2 or 0 degree front caster blocks
0 degree kickup (this isn't something I'd do as it sometimes causes weird handling problems, but it's a choice...)
LOWER THE CAR!!!! 6.5 is really way to high. We run at about 4-4.5mm. Of course, this depends on the type of track you run on!!! Maybe it's pretty bumpy...!!!

On the rear:

2 degrees of toe in causes more steering OUT of a corner, less in. You could go back to the 3 degree block. Also, try the R3-0 block. The 0 antisquat will allow the car to accellerate harder in and out of corners, but make it a little washy in a straight line. Might be something to try.
0 out the steering EXP. Like Airwide said, most people run 0 or a tad negative.
I tried the battery forward and it made the car too twitchy into corners. Didn't like it.
And lastly, LONG wheelbase. Believe it or not, LONGER wheelbase gives the car more steering. It doesn't make sense, but, for most r/c cars, this is true in relation to the rear hubs-to-outdrive placement.

Hope this helps out...

With the track conditions here, a softer rear spring gives more steering, but however less initial steering. And that's with the oneway installed.

If you don't use the oneway, I recommend you to install it. The corner speed is so much better with it at all corners but hairpins.

Talking STEERING GOOOD!!!!!!

i believe that one can always steer a little less, but one can't steer more if the car has no more steering to offer. more steering than the average bear means more alternative lines and places to pass the average bear. Just don't expect to pass Tony!!!!
