thermal shutdown rc10gt electric
just finished doing my 3rd conversion of a rc10gt to electric brushless
but this time all my lhs had on hand for spur gears are the old original 32p gears(usually use 48p gears)
and its messing with my head gearing wise
and I get thermal shutdown after only 5 mins
rc10 gt trans is 2.6
64t 32p spur
21t 32p pinion
tires are right at 95 mm tall
motor is a 4 pole 4300kv
any suggestion's on the proper pinion for this setup

thanks for approving my first thread lol
well did some more tinkering and threw a 13t32p pinion in it(only othe32p pinion I have on hand )
its much better, bashed it in the dark in my front yard for about 15 mins in tallish grass
motor is now cool enough (does have heatsink with fan )
but is still getting pretty hot (not enough for thermal shutdown so far but still hotter than id like)
I cant go down many more teeth on the pinion ,due to motor will hit the trans
an since what ever I do I will have to order something what do you all recommend
don't want to stab in the dark and order one on a whim

Yeah, the 21T pinion gear seems like too much gear to start with. The 13T pinion puts you in close range of Associated's recommended FDR. The whole 15 minutes of driving in "tallish" grass bothers me, and should bother you as well. That grass is probably your main culprit. In a situation like this, an infrared thermometer would be a good friend to have by your side to get accurate temps of motor and gear.

I went down to a 12 t and she is a champ now grass or dirt
ran 2 full 5000mah 3s lipo and no thermal problems
used the old rule hold the back side of your finger on it and if you last to the count of 5 your good lol(my thermal laser probe has a dead batt)
now I just need to finish up my second conversion
really wish I was able to post pics lol
