Guys, I am running orca 11,5T with LRP SXX ESC, with 64p 103T spur gear and pinion gear is 34T. After several laps running, the motor is very hot. I think the spur and pinior gear are not matched. Could you suggest me what pinion gear I should use?
The track is about as big as backetball court
Thank you guys
Well, as always, it's hard to diagnose without actually seeing the track layout, but I would think that your FDR(which would be about 6.22:1, if my math is right) might be a bit tall for an 11.5 motor(especially if your ESC has any timing advance in any of its throttle profiles, which I think the SXX can do), so you might try going down a couple of teeth on the pinion, maybe 3 teeth, & keep a close eye on the motor temp every couple of minutes(would also be good if you have access to a temp gun, maybe someone at your track can help you there). If you can monitor with a temp gun, I'd try as a rule to keep the motor temps below 170 F, that should keep your motor from being damaged....
