So today at my local track I'm running the new castle 1515 2200kv Sensored motor with the MMX esc. This was my third time running the this new setup. After about running 3 packs. The truck( losi 3.0 truggy) just stop and lost all power. I still had power going to the servo but no forward movement. I figured i hit LVC. SO i put in a fresh battery and nothing. No beeps or noise. Still had servo movement but the truck did not move. So i swapped another fresh battery and same thing. Servo moves fines but no beeps on power up. And truck will not move forward. Any ideas? I also try hookup it up with my PC with castle link and whenever i try to change a setting. Its telling me it cannot Save because it failed to connect to the esc.
