CC S-2 Running HOT!
 

I have the new Castle Sidewinder S-2 version on a 3S/35T 1.9 scaler that keeps going into thermal shutdown. I'm running the stock spur/22T pinion with 1.9 tires. Nothing is binding and the gear mesh isn't too tight. I swapped out the motor with another 35T, checked the mesh and tried again. Same problem. Is there an issue with the S-2 ESC? I have four older Sidewinders and never once thermo'd them. Any thoughts?
