jta - What is your current setup? Are you racing on asphalt or carpet? Are you using foam or rubber tires?

Mike D- We're racing on a cement racetrack. I use sorex 36R tires all around with med. inserts. I used green springs in front and silver at the back, ball diffs front and rear. I also use F+2 mounts in front and R+2+2 at the rear.

It sounds like you're transferring too much weight to the rear on accelleration - this is taking all the weight off the front tires so they aren't giving you any traction.

Try stepping your rear springs up a notch (use one color harder) and see if that improves it. This would reduce the amount of weight transferred to the rear.

You could also try stepping up the oil in the rear shocks a touch. This won't reduce the AMOUNT of weight transfer, but would SLOW it down.

jta - For more steering exiting the corners try a front 'spool' diff, tighten your front ball diff, use less caster, or use R+2+0 rear block. Those changes are listed in the order of most steering to least steering increase on turn exit.

BTW - Your springs sound very soft... have you tried stiffer front and rear?

I would agree with boomer. But from your setup, it seams that the front end is a little soft. Green is the lightest spring you can get and that seams way too soft for the front. I would try the stock setup and work from there. It may be as simple as too much droop in the front. If you have too much droop, this would allow the front end to lift too much under acceleration and would transfer too much weight to the back.

Also, are you seeing a push when you enter a corner or on exit or while in the corner?

Default 200mm conversion

what would the 200mm conversion for the tc3 do? what does it make better (other than fitting the better bodies i want)?

A little bit more stable at high speeds. but not legal for sactioned races... you also have to chech with your track if they will let you race 200 EP cars.

You can try reducing the droop on your front end and/or add rear antisquat (if you're not already running the two degree block). Stiffer rear springs and less front caster may help too.

You probably started with gold in the front and silver springs in the rear didn't you?? and the car had a slight on-power push, so you went down on the springs until you ended up at greens....right????

Rule of thumb..... Matched springs front to rear at worst, never-never-ever use softer springs in the front, you may get it to work, but it drastically increases the complexity of your set-up..... Do you have the origional chassis or the updated one using fdroop screws?? Definately limit your droop setting on the front, 90% of the time that a slight handling problem is amplified it is an improper droop setting....

Like stated before start with the stock set-up and work from there, but this time start by limiting droop.

Less front droop = more on-power steering

Less rear droop = more off-power rear traction

Limit it 1/2mm at a time until the characteristic you are trying to achieve starts to reverse, then go back 1/2mm, and stay there.....

jta

1. front one ways would help

2. try to alter the shock position, try putting the front and rear shock positions inward, in order for the front to have more side bite, exiting the corner...

3. install losi steering knuckles, and add a little toe-in in the front

4. try all blue springs, or blue front, green rears...

5. remove the sway bars...

NTC3NUT

what was the modifications you had done to your steering and/or shock tower?

also, have you ever experienced in your NTC3, the front and rear shock towers keep on loosening from the bulk head (diff case)... if so, what do you do to remedy this...

thnx...

When you add toe-in, it decreases steering a lot and makes the car easier to drive. I would suggest trying .5-1 degree of toe-out. Look in the back of your instruction manual and read all of the tuning tips. It talks about a bunch of adjustments that will increase on power steering.

Actually toe-out increases steering going into the turn, but looses steering everwhere else including on-power....

Toe-in decreases initial steering response, but gives more oer-all steering, and has a smoother feel thruought the entire cycle......
