Dear All,
I need help on what to do to reduce motor temp.
The track I run has a straight approximately 130-150ft with flowing infield.
The ratio I used in 7.7 on a LRP X12 10.5 with light weight cooling motor can upgrade added to give it better cooling.
ESC : Hobbywing 120A XERUN with upgraded caps, 4 caps with approx 1600 micro farad.
S/w : 518
ESC Setting :
DDRS : 3
9 : 4
12 : 4
13 : 7
14 : 4
15 : 7
Track surface temp is 55 celsius
After 5 min run, motor temp is 97 Celsius. The run is pace with another similar brand car, motor , ratio is 8 and different brand esc. The other car temp is lower. Both car have similar pace and speed
Previously ran this motor with another ESC on the same layout. The motor temp is approx. 8 degree celsius cooler under similar track and air conditions.
The motor is cooled using a big 40mm fan which is super efficient and big volume of air.
Any recommendation on what I can do to keep the motor cooler.
Thank you in advance.

Hi there, I run a similar setup as you but with a much lower motor temp.
My settings are:
FDR: 7.6
SW:518Stock
#4:7
#9:6
#12:4
#13:6
#14:4
#15:6/7
straight is 35m long, with semi-technical infield.
outside temp: ~ 22C, track ~ 35C-40C
motor temp after 6 mins: ~ 60C (x11, 10.5r, Zero timing)
It looks like your motor is quite hot. Check your pinion & spur gears to make sure they are not binding. Make sure your transmission is also smooth. Are you running any motor timing?
