Jason you ran blue springs in the front ? If you can't get rear traction, slightly lower the rear droop ( from 3mm to 2mm)... Tc4's don't like too much droop in the rear... What about your steering expo, make sure you're between -40% and -10% ...

Yea I went to the Blue springs and the lower roll center made the car roll and tonne less than before. But I dis sacrifice rear traction. Not too bad but once corner in particular I likes to drift out due to a bumpy section.

I was thinking of trying a roll bar in the front but have to tested that yet.


Also our track was recently changed and some sections have not been run on much yet. and our carpet is old

P.S. what is the idea to changing the expo on the steering? Slowing down the action or speeding it up?

Yes , the idea behind the (-40% to -10%) expo is to slow down the steering servo's sensitivity around neutral, thereby stopping the whiplash effect that might cause the rear to seem loose. It also gives a smoother feel, that results in faster laptimes and consistency...

I have read somewhere that Paul Lemieux uses -10%, the Awesomatix experts prefer -35% ... I run -30% now , and I am learning the new racing line...

Jason, I forgot to mention that you can also use high throttle expo(+40% to +100%) to punch out of turns faster, and you can also add throttle acceleration (50%) to that , so you can out accelerate everybody... That's the shaft drive advantage !

Anyone running 21.5 or 17.5 stock on low/medium bite carpet? I've been playing with 15.5 front/12.5 rear springs and various droop settings but the back end always wants to slide around. Spool up front..... won the USGT main tonight but curious to see what other setups anyone is running.

Also, what camber link positions do you guys like?

We use Solaris medium tires FYI.........

Another radio setup tip dual rate down to 70% . 100% is too much, and causing a loss of corner speed ...

Personally I run my radio so that it has full range and the outputs directly reflects what inputs I make.

I then drive the car.

That's pretty low for a tc4 , but you still need a light battery pack to compete in stock : tp3200 40c (208grams) or lighter...

These packs are heavy (over 300grams), and only necessary for mod racing , where the extra 100grams won't matter much...
