I just got a tlr 22-4 and decided to try out a Turnigy Trackstar 120A turbo esc and 5.5. All I can say is wow. I'm totally surprised how smooth power delivery is and how controllable (for a 5.5 turn motor) it is. Does anyone know how the drive frequency setting affects power delivery? There were a few other settings on the programmer that I didn't fully understand but I can't recall right now...

What is a safe operating temperature for the esc's? I temped mine on a couple of runs and it was around the 120 degree F mark.
