You can lower your rpm's by about 200 rpm's by adjusting them from example #3 to #2. They seem to pull better mph with the lower clicker numbers. That motor spins at 7850 rpm's so shoot for 8000 rpm's, they do sometimes read a little high. You can also add some pin weight about 1 gram per 100 rpm's or reduce your final force on your spring from a 230/380 to 230/ 350 this should reduce yor rpm's by about 300 rpm's. For even more grin from your setup, drop two teeth on top gear(from 26 to 24)!
