hi all

Since a few weeks our clubtrack is on carpet.
My car is riding better than ever before because i have 4° casterbloks
installed , before 2°.

there is just one small thing i would like to get rid of.
there ar lots of sharp turn and following is happening when cornering.

I drive full power untill the breackpoint, turn in with 0% throttle. As the
speed drop the car turns charper. then comes the point where it gets
unpredictible. At 90% of the time it takes a good turn but the other 10% it
turn in a bit sharper and the back loosen grip and breackout. this is
mostly after half the turn, just before i want to open throttle again.
This all take place in a split second so i come out of the curve pretty
ugly, and slow.
i use tiregrip "Dr gripper " 100% on the rear and +- 80% on the front tire.

From my point of view it seems that on slow(ingdown) speeds the front gain
much more grip then the rear, and makes the back breack out ).
Any suggestions how tho fix this ...
I let you pass next race .....

I eecomend that you replace vehicles front differential with a one-way-bearing -
this will help your vehicle go straight out of a turn. Increase the front spring
rate - this will give you better traction/grip (applies to all wheel drives) out
of turns! In addition decrease rear spring rate - this helps to prevent rear
tire traction loss. Really you don't want your racer to lose traction or to
burnout!



After one-way-bearing is installed: you may need to practice - because practice
makes you perfect - give yourself plenty of time before your vehicle reaches a
turn - let off on the throttle - you may apply a small amount (Rear Wheel Only)
of braking - too much brakes and you'll lose control. Just BEFORE vehicle comes
out of a turn - Straighten up and PUNCH IT!!! Your vehicle will go straight away
every time! >>> Need more cornering traction?<<< Remove both anti-sway-bars!



Take heed that when using a one-way set up - vehicle has NO front brakes!

I like foamies or soft slicks for carpet. I like to use the HPI Firm (blue)
inserts with a set of soft tires in front and med soft at the rear

thx for the tips.
i have a one-way, nut i dont like it on small tracks becouse it gives the
frotn driveline a hard time.
I try with softer rear prings.

I have no idea if this would be any help, but I noticed a guy in our club
who gets top results with a TC3 has his car set up so that with the Tx
throttle in neutral, there is actually still a small amount of throttle
being applied. In other words, with the Tx throttle in neutral the car will
move forward (slowly). I have no idea why he does this and he didn't seem
able (or willing :-) to explain it to me, but it is an interesting idea.

I think it might have applications in 2wd off road (which is my main
interest anyway) to prevent that "unsettled" feeling when you get off the
throttle too suddenly?

Anyway, its something else to have a play with :-)

When you adjust your throttle trim if you set it so the vehicle, when on
the ground, just lurches forward a little bit, you will have lots of
coasting when you let off the throttle after accelerating. If you adjust
the trim the other way the vehicle slows down considerably when you let
off the throttle, after accellerating. It can be a drag brake of sorts.

It removes the sudden unloading of the rear suspension and loading of the front
when you get off the throttle quickly. Makes a bigger difference in stock than
modified racing.
