brushless losi 8b

[FG101C]

The track was requiring alot of braking, I will definitly check heat on individual wires and connections. Mesh is good, diffs are fresh, I'm using the 8ight-E body so airflow isn't a problem. Bearings all check out. Can't run now for a week or so as the track is getting a rebuild. I really think I should pitch the Losi motor mount get a RC-M mount so I can get a 48 tooth spur in there. That or put the truggy ring and pinions on the diffs (43/10). The Losi motor mount makes changing pinions so easy though, I could try making a way to shim up the diff with with some aluminum plate I have laying around.

Really the temp, speed and handling are good on 4s, but this goes against everything everybody says. On 4s the motor rpm are 23,680, everything says to be between 31,000 and 35,000. On 5s rpm are 29,600 and the temps go up, geared down.

Only other question I can think of is. Are brushless motors super sensitive to undergearing, more sensitive to undergearing than overgearing? I know brushed motors are sensitive to overgearing, just wondering if brushless is the reverse?

Thanks again.
