doesnt that car have a soild rear axel? I think don't have

about how fast do u take the turn? Fast

how does everyone else take the turn? fast than me but they using foam tire.

I daresay this is the most important piece of info we need.

other people are the basis of the observation that your car needs more steering in slow, tight corners, so what makes them handle it differently?

me43

hm...

i guess if brake a little it might help

but if you servo throw is less than everyones than yeah u will have under steer


a rear diff. might help

Sorry, I not understand what you mean.

okay, what tires are you using? Because whatever they are, they won't let you go as fast a foams. Foams have much more grip. I run rubber tire and foam tire classes, and my lap time with foams are on average, .7- 1.0 second faster... per lap. That is very significant, and if you don't have foams, you will be glad when you do.

To use rubber tires against foams, you need to use diffs. Rubber tires don't have enough traction, so you have to use your braking ability as an avantage if you use rubbers. Plus the car should become much more stable on corner entry and exit.

Personally, I find one-ways to be fast, but not very consistent on tracks where you encounter tight 180's and sharp angles created by parking lot style tracks.

i think a rear diff. will help alot


because i belive ur car has a solid rear axel

mind checking?

me43

o, ok

the car only has a rear diff.

my bad

Im2lazy

How would he have a solid rear axle with out knowing he bought one?

mike, the gt4 rtr comes with a front solid axle, but he bought a one-way to replace it. I would guess he hasn't touched the rear diff.

I am running rear diff.............front one way. OK.......I change to foam tire and do some brake when go into a 180 degree corner.

me43

i thought it came with a soild rear because yokomo makes a kit with a front oneway and a soild rear

Im2lazy

In order to properly brake with a one-way, you must first have all things properly set on your car. The front spring preload must be equal on both sides. The rear droop must also be equal, and you should have very minimal rear droop too, otherwise too much weight will transfer making the car lose traction for braking.

Also, you should lower your brake epa to about 2/3 of what you would have if you had full time 4wd. Still with all of this, you still cannot brake and turn simultaneously.


Hope some of that is new.

That is the old gt4 pro. The one made for lola bodies. I don't know if that is how their present pro kit is equipped, but an RTR equipped with a rear solid axle and a front oneway would be a flop because that would be impossible for most RTR buyers to drive in even the simplest patterns or cornering manuevers.
