I have 2 tp 5000mah 45c 6s, but I've ran it on 10s in the field no problems
so your saying 10s ran cooler than 8S but with the same motor?
yea i have a 17 on it now im running at the track. im going to wait for traction and a new surface before i go any further ,its all just hard pack with an inch of silt on it. but now i know if i limit wheel spin it runs much longer and much cooler. (thanks cain)

Sorry auto2 I forgot to mention I'm running a MGM esc, but I do have a Baja with a cc running 8s 16t pinion w/56 spur and that gets hot in the dirt but cool on the street so I'm sure the extra 10+lbs and taller pinion isn't gonna help

seems motor needs a load (like someone mentioned) and if i have too much wheel spin it heats up. huge difference going from 200 to 150 and 12 minutes to 17 minutes run time just by not giving it more throttle than the tires can handle

Current is proportional to load. Thing is, it actually takes a lot of power to spin those wheels like that. It's pulling a lot of current at those times.

Have you found the current limiting in the ESC settings to make any difference?

current limiter? not sure. would have to do specific testing. going by the data log it works.

i ran it today but not on the track. on the corn field next to the track. full throttle back and forth.not too much wheel spin just cruizin at 50 MPH. motor was 120 degrees f.

What motor, esc, gearing, and batteries were you running?
