Hello, I have a 2wd Torment with a 15T brushed motor running 2s lipos. I only get 5-10 minutes of run time on a 5200mah 50c 2s lipo. The ESC is set for Lipos and I performed the ESC to Transmitter calibration. I have the STX 3 transmitter. The battery is at 3.9v per cell when the truck hits the Lvc and has about 50% power. The motor is new and is the exact stock replacement. Also have stock gearing. I can use the same battery in my Arrma big rock for another 10-15 minutes after it cuts off in my Torment. Also, I sometimes get a lag in response from the controller to the truck and controller has new batteries. Any ideas?
