Weird problem here guys. Im using the 1s esc for spec sedan. I had it paired up with a revtech 17.5 motor with the high rpm rotor. It was just fine except I picked up a motor with the high torque rotor. I soldered the high torque and took it to the tracks today. This is when the problems started.

When gunning full throttle, it would be very delayed. The motor would spin at about 50% for half a second, then finally go full throttle. On the track whenever this happened, it sounded like a spur gear getting stripped.

So I came home and switched motors to the old one.... Same problem! Then I switched Rotors. I thought i figured out that the high torque was faulty. Using the high rpm was perfect. That fixed it! Or so I thought. I tested it twice and it was working perfectly with the high rpm rotor. 10 minutes later, the problem is occurring again. It won't go to full throttle immediately; rather it waits .5 seconds then goes. I've done everything except switch escs.... I hope I don't have to.

Any help here?
