Default Fixed flipping problem - now I need more steering

I posted last week about having problems with my car flipping when going into turns at high speed. I fixed that...but now more than ever when I am turning...the car seems to always want to go wide. I see everyone else taking turns and they turn on a dime. My car just seems to always wanna make a huge circle turn. What is the deal?

The term is called "Understeer" in the Front (or Push). It means you have less grip in the Front than you do in the back.

How about posting your Car and Set-up so we can have more information to help you better.

FRONT -
springs = copper
shock oil = 40 wt.
sway bar
double purple foams

REAR
springs = red
shock oil = 40 wt.
sway bar
purple foams

the droop is set to stock. that is either 4 in the rear and 6 in the front...or the opposite of that. I forgot. I am not by my car right now. IF you need anymore info...let me know.

Try some heavier shock oil in the Front 45wt and using the same compound tire Front and Rear.
I don't think I remember what kind of Car you have.

I'm not sure what car you use, but I'd start with some plaid front tires. (purple with an orange outer ring so it can't fold under) Also, 40wt oil might be a little light for foam tires, but that kinda depends on what pistons you use. I think people could help you out alot more if you posted your entire setup with shock locations, camber link settings, caster, camber, tow, etc....

Please note: In the pictures, I have the red springs on the front and the copper springs on the rear. That was just a test...and the real setup I was running was red in the rear and copper in the front.

ok well go to the F-0 block up front....and maybe lean the top of the shocks in one hole in the front...should give you more bite and steering

I really wish I could give you some better answers than I already have, but I am not familiar with the handling traits of the TC3. All I can do is give some general recommendations that should apply to all R/C Cars.

I ALWAYS run the same Compound tire and insert Front to Back. In my opinion, It is much, much easier to set-up and tune a chassis this way.
Try not to get too far apart Front to Rear with the Spring rates and Shock oil weights. I usually run no more than a 10wt difference from the Front to Rear.
Your car will almost always be much easier to drive and tune if the front and rear "Rates" are closer to each other. What I call a "Balanced" set-up.
Get to know your Car well, make ONE change at a time so it can be evaluated properly. You need to know what works and what doesn't.
I'm sure that there will be plenty of people that will disagree with my statements. But it has always worked well for me.

I also recommend a hop over to the TC3 thread, as the people there have alot more experience with the Car than I do.

Pops, he's running foams, you don't run the same tires front and back. Here I'm going to give you a good setup, all the fast tc3 drivers at my track run it.

Front:
70 oil
Purple spring
2 piston
swaybar
Plaid Foams

Rear:
60 oil
copper spring
2 piston
swaybar
Purple foams

Low roll-center all around (inner camber holes most upper and inner), and shocks stood all the way up front and rear. Make sure you have enough droop, too, try 4 in front and 3 rear (depends on tire size).

Sorry I missed that.
Never ran Foams on my Electric Car.

For Nitro racing on parking lot tracks I use what ever compound Foam works F/R. For Big Permanent tracks , I try to run the same compounds F/R. Usually this works well and gives me more even tire wear.

Actually Axiom 5B you are not correct. If he is running dprp/prp it is ok to try dprp/dprp. It's not uncommon for foam carpet racers to use double purples in the front and rear if the track has tons of traction. Sometimes it's the only way to get the car to rotate.

Where do you race Axiom 5B? What's your local track? And who are you if you don't mind me asking?
