I just installed a Trackstar GenII 1S 120A in my WGT to try it. So far, no problems. I did pick up the program box and the first thing it did when connected to the PC was update the ESC to 2.02. For blinky, you need to switch to profile 1, rename it to what ever you want so you remember it, set timing to 0*, set turbo to 0* and the white LED comes on to indicate no timing. Then change gearing and the timing on the motor to match the track for blinky. If you just calibrated out of the box and have the timing cranked up, the default "Modify" profile HAS TIMING. Turn your motor timing down to 10* or less until you can get to a PC with the program box. You're probably getting cogging from too much timing.
