| Hobbywing Justock fan?
I put a Hobbywing Justock esc and brushless motor on my scx10. It performs great so far, but the fan spins stupid fast using 3s lipo. Would it be ok to just not run the fan on this setup? Also what is a acceptable esc temp so I can keep an eye on it. Also it's a 1900kv motor with stock gearing.(87 spur, 20 pinion) Thanks. |

Have never used a fan on any of my rigs in 20 yrs.

BUT I run the 120 ESCs in my go-fasts without a fan, you should be just fine. I wouldn't worry until you start getting to the 150 deg range. A good field check is if you can't hold your finger on it for about 5 seconds, then its time to cool down. But with the lack of timing adjustment and low gearing, I really don't think you will ever get close to that. With the 17.5 on 3s, I would almost try dropping the pinion a few teeth. When I am doing crawling I run a 16t pinion, when I need a little more speed I run 18-20T pinion with an 18.5 Novak on 3 or 4s. This was years ago, but I never could get the 120s to run in my crawler. I never get it to not have a delay going to reverse, and the low end was a little squirrely. I bet they have updated their programming since then. I love these ESCs in my 1/10 go fasts. | |

Thanks for the replies. I've ran it a few times now with no fan and it's fine. Doesn't really get hot at all. So far it's been a good esc/ motor combo for me. Enough speed and still crawls great. Thanks again!
