Racing in a 17.5 class on carpet track with rubber tires. Have a Speed Passion LPF 2.0 ESC. Any ideas on what size pinion gear I need and what settings I should run in the ESC (timing, punch, etc.). I have not adjusted the timimg in the motor. The motor is a Vector X12 from LRP. I would appreciate any help. Thanks.
I did some testing this weekend with the x12 stock spec motor from LRP...
I know a speed passion thread, but anyways, the motor was very difficult at first. But it's going to be a very good motor...
In the main I finally got my fast lap to .1 slower then I had turn in a previous weeks at the track.
but the biggest difference is the fact I have few more teeth I can go up on the motor. It recommends 210* degrees in the manual. At the end of the 6 minute A-main the motor was 138. Fast lap was a 8.4 (small track)
I was running a Duo2 with timing at 8 and the punch was maxxed out , and after the race it was temping at 187*. I found out you can not run the GT2.0 at max timing (26.75? I think)with the stock spec motor. I am running at the 22* (number 7) and the DRRS is maxxed out and right now. I'm at 4.43 on a 68x36 track.
LRP recommends 4.0 they are pretty much right on...
I'm also running a fan on the motor as well... hopefully that will help
