Mechanical brake / Castle Neu problem

Hello again everyone :D

I have a question regarding the gearing on my setup now. Im currently running the 12t pinion with the stock 50T spur, which performance wise is working perfectly. Similar, but faster to my nitro car, and no crazy wheel ballooning etc.

I measured the temp of everything after my last run, and found that my motor was fairly hot when compared to the ESC and batts.

The ESC was about 30C, the batts were 33C but the motor was just under 50C (degrees in Celsius).

I looked up the thread on motor/speed/batt temps which has

Hot motor, cool controller, cool batteries = undergeared
Cool motor, hot controller, hot batteries = overgeared

So I guess my setup is currently under geared. Does that mean I need to go up a couple of pinion sizes to "gear up", or does it mean that I need to go down a few?

Thanks guys :D

That is correct. To gear up, you can either get a pinion gear with more teeth, or a spur gear with less teeth. Both will have the same effect.

Hmm, that's a bit sad, as my run times were awesome with the 12t lol. Thanks for the quick answer tho, I'll try the 13-15t pinions and see how I go.

I just wish my 1600kv medusa would arrive already! 2200kv is way overkill for 7s a123s lol

50C is about the coolest temps you can get on any motor after a run. There is nothing to be concerned about until you exceed 175F or about 80C.
