MTX-3 Adjusting Turning Circle?

I am currently running a MTX-3 on a tight small track and find they I don't have enough steering?

Here is what I am currently running.

- Ackerman A for Servo Saver
- Front Camber -2
- Rear Camber -2
- Front Toe -0.5
- Rear Toe +2
- Rear Right Height : 5mm
- Front Right Height: 4mm

Do I have to adjust any of the above or is all about the servo?

Thanks for your help

Sami

I also run on a fairly small tight track and I find that I have more than enough steering. In fact, I had to go with a stiffer front spring.

I'm running the stock setup wih the following changes:

Grey(stiffer) front springs
Front diff with 10,000 oil
Rear diff with 5000 oil
"C" roll center blocks
Long rear camber links
0.5 deg. rear camber

BTW, i'm using rubber tires(Sorex 40R).

Check your servo saver spring tension or your up-stop setting. The servo saver, if set loose, may "give" not allowing enough steering throw. The up-stop setting, if set too much, may not allow full suspension compression thus reducing steering.

A High idle/neutral throttle or a clutch that engages too early can reduce steering in tight turns also.

You could increase the rear uptravel so that the car gets more steering, or if you want, swings around... Or you could make the front diff oil lighter so that it turns in faster... or thicker rear diff oil to make it rotate more out of a turn....

I can only give general advice.

And on where you need the steering to improve most... in or out of corners or just plain everywhere!


Grey springs! wow Freekah! Like I told you my MTX2 is running HPI electric springs ... Two totally different beasts I guess

What another information do you need?

I need more steering exiting the corners with a one-way diff, so I can't add any oil to it. I am

-using stock diff on the rear,
-and using the stock shocks (blue).
-Also got the shocks mounted on the 2nd from the bottom
- Running foam tires:, 40F, 37R at 18 Celius(33 F).

What happens when I hit a hairpin is that car seems to go very wide out the corner even if I apex properly.

Please Help

Reduce front droop

Increase caster

Reduce rear toe-in

Thicker rear shock oil and/or stiffer rear springs

All those help increase on power steering. Try them one at a time in that order.

Freakah,

What's your rid height and droop?

Still run rubbers? I would still love a great rubber setup.

Still running 10k front and 5k rear? How about shock wt.? Front and rear link positions?

Thanks,
Puma

Reduce the front width of the car to about 197mm - this will fix your problem

Forgot to mention, your front sway bar can increase/decrease the turning circle of the car. I suggest leaving this flat (softest).

i switched to 30k rear diff oil to get more steering helps alot

next if i need more i will probably try the stiffer rear sway-bar

you could also try a little less rear toe in but i like to run 2-3 also
