Funnily enough this is the exact opposite of Toadeh thread :D, anyways:
Yesterday, I had my first race with the CR2. It was a non-permanent track on a sports hall, with most of the turns on the very slippery floor, the others being on carpet.
Well, I had the hardest time trying to make the car steer on the slippery stuff. On entry, with steering at full lock, the car had to be almost stopped before rotating slowly to the exit. A shame as the CR2 was brilliant everywhere else, powering down nicely even on the dreaded slippery floor.
My car was setup exactly as per the base setup (Oswestry) that can be found here:

I am running the idler mod, standard slipper, Orion 7.5 and IP 4200 35C saddles. I also use a pinion diff; it was rather free with 1000 cps.
I tried all kinds of tyres: Minispikes, Minipins worn or not on the rear, Staggered, Minispikes and Minipins on the front. I ended with almost new Minipins front and rear.
I went to the 30WT-green springs combo on front, I even fitted silvers, but it didn't made much difference. I tried the inner shock hole on rear bones to make the rear softer and have more droop, but the car felt less sure-footed with no steering gains, so I went back to the medium hole.
Weight-wise, I followed the 65-35 rule by using no weight on front, 30g near the motor. I also tried 70g under the cells but it didn't felt any different. As you would guess, I quickly added lead on front by stuffing 10g behind the bumper and 35g under the servo. Again, it felt no different, dead slow on slippery corners.
What I didn't try is:
- use less rear wing/a front wing
- add way more weight on front, like using a brass bulkhead
- soften dampening (it feels rather stiff like this)
- mess with links, roll points, antisquat, etc
- take out the idler mod
In fact, the CR2 felt a lot like my old X-6. there were lots of mid 2WDs on the track, but rear-motor cars seemed slightly faster on that day. So is this mid-motor related? Or do you have to use the brakes mid-corner?
Sorry for this long reading but I had to explain everything. Any help welcome! :thumbsup:
