They helped a bit but didn't fix the problem entirely. Temps look good too, 140* on the motor and about 100* on the esc. Any ideas?


Here's my setup

-Novak ballistic 17.5t with high rpm stator, 40* timing on end bell
- geared 32/72
-garodiscs with stock spur
-Novak gtb2 w/x-drive esc
-venom 50c 5000 mah 2s lipos, full size.
-airtronics mt4 w/rx-461 receiver
-spectrum 6040 servo
