stopped off at hobby people today and picked up a 20 tooth pinion. did a quick test about an hour or so ago. noticeably faster, didn't run it long enough to test motor and ESC temps (might do that tomorrow). after iv figured out the gearing im going to up the timing, see if i can't get just a little more speed while loosing some of the abundant low end torque (im seriously afraid it's got to much torque and might break something).
respect your elders. we've been around longer and done more stupid things than you, therefore we're smarter
