Humm would a small fan fit on the rear shaft? (pulling heat out of it)

Yes but making one fit would be interesting, but thats an AWESOME idea and when I get my 80MM for the LST2 Im gonna give it a try with my 40MM fan

seems to me that would cause alot of unneeded drag on the motor and cause more heat

I'm trying to figure out the gearing for my D8 buggy. I'm using the 60mm 2000kv motor. On 4s I had it geared 15/48, the buggy uses truggy gearing in the diffs (43/10). It was good like that, 20 minutes run time but a little hot. Temps like that were right at 170-174. Could use a little more speed.


Today I wanted to try 5s. So I geared it 13/48, got a little hotter around 180. Next I tried a 16 tooth pinion, ran it about five minutes and checked it, temp ok. Ran another five minutes and it was right at 190. Ok so 16 is over geared, but is the 13 under geared? Or should I try 12, or go back to 15? Ordered the heatsink, but is that really going to make a difference? What would a 45 tooth spur do with 13 or 12 pinion or even the 15?

Batteries used are Polyquest 4s 6000mah and Hyperion 5s 4350 25c. ESC MMM v3. Batteries and ESC are running warm at best, it's just the motor getting hot.


I'm thinking I'm probably best off using the heatsink and the 4s 15/48 setup. Just wanted a little more top end.

Any suggestions are greatly appreciated.
