I've run TPPower 4050 series motors on 4S, one a 1570KV, the other a 2100KV. I haven't run any crazy gearing on them; the 1570 has been run on 11 through 16T and the 2100KV has been run on 11 through 13T. And that's with the stock 52T spur.
The 2100 is scary to run; geared at 13T it'll easily reach 150, early 160s at the end of a 10min run. The 1570 is a little more sane, but the motor temps can still hit 140+ all the way up to 150+ at the end of a 10min run. The batteries take a big hit too. I've had a 4S 6500mAh pack hit 138 degrees with the 2100 and maybe 128 or 132 on the 1570.
The Kuron motor isn't as brutal; temps will be around the 140+ range for the motor and maybe 120+ for the batts.
I'm always running a fan on whatever motor I'm running, so I'm starting to wonder if my gearing could perhaps be either low or possibly high? I know that undergearing a motor can also result in high temps, so maybe my gearing is too low?
My Shogun is run on a small track; decent amount of turns, maybe a 30-40yd straight. I don't usually brake for the turns, I just let off the throttle and try to coast through the apex and then get back on the gas to power out. It's not full throttle either, maybe about 1/4 to 1/2 throttle.
Am I missing something in this equation? Common sense is telling me that my motor and battery packs should be cooler, but they're not. Which leads me to think that they could possibly be undergeared. I'd love to run the TPPower 2100 motor, but I value my lipos too much to just throw em away by running that particular motor.
What do you guys think?
