Hello ARC Nuts !
Just back home from a great day of testing at Huge R/C with Hara (also running his R11 by the way).
As you may know already, Huge RC Circuit is renown for its extreme high bite condition and today was not exception.
Tho, it was just a normal "week day" and not a "race day" and getting the traction roll factor under control was already quite a challenge.

After glueing the side wall (reaching the top radius) of the front tires (mandatory on Ride - REX34 from very fresh), here are the main set-up changes I applied during the day:
- Flex-wise, I started with 100% of all the screws mounted everywhere (top deck, motor-mount, servo/steering rack/posts (connected to top deck), etc.). Just ALL of them screws. Grip and risk of traction roll are so high there that it is better to start very stiff and soften things up if you feel like it.
- Rear toe-in reduced from 3° to 2° (flipped the #0 blocks with the notch "outside")
- From mid position, the rear shocks straightened 1 step up on the shock tower.
- Front inner camber link spacer increased from 3mm to 4mm.
- Axon shock oil changed from 40wt to 45wt (Front and Rear.
- Axon diff oil changed from 7.500cSt to 10.000cSt.
- D/R reduced from 95% to 85% (100% being "full lock").
- Servo speed set to -3 forward/return.
- Steering Expo: 20% (Sanwa M12).

With that set-up, the R11 was very pleasant to drive and fairly safe from traction-rolling. Good roll balance with obviously a lot of steering.
I tried the GSF-II 0.5mm body (white) at the end of the day.
It was initially a little too edgy (generating even more steering) and with the existing grip, you didn't really want anything more sensitive but then, after 2 minutes within the run, it felt all right and safe enough. Improving my best lap-time by 0.2s, so it's a keeper.
