We run on a 90 x 40 size carpet. Laptimes are in the 10 to 11 second range. I have approached this two different ways.
X-12 17.5 set with 4 dot timing shim. Speedcontrol set at 1,5,10,0. Rollout at 3.5 inches. Lost a few feet down the long straight. Laptimes with the fastest. Lost main by .2 seconds. Fast lap was almost full .2 seconds off the fastest. Did not fall off and gained 2 seconds on leader in last 3 laps.
X-12 17.5 set with 3 dot timing shim. Speedcontrol set at 1,5,6.0. Rollout at 3.5 inches. Set fastest lap in main and won. Lost a few feet down the long straight. Very good rip through the infield. Faded slightly in the last 3 minutes.
Overall impression is that higher rollouts are in the cards for either of these setups. Did not feel boost kick in for either. The 3 dot timing for the motor yielded strong performance in sweeper type corners. The first 50 feet of the straight was outstanding. Throttling was smooth and linear. Very race-able.
More later.
