Right. I forgot about that but should be able to solve that issue pretty easily.

Had the same problem with that speed controller. Checked and reset everything before I found the sensor cable was coming out of the esc. Pushed the cable back in all the way and the problem went away. Apparently the esc goes into a sensorless mode when the cable is disconnected and does not give you any warning mode ( flashing / blinking lights, ect ).
Was this at NorCal? If so, that crash was pretty epic

Darn. I bet that's what it was. It was fine in the pits and for the first lap or so - then it went out on me.

Yea @ Norcal. Good track. Good people. Definitely recommend it. I guess I was famous for the day A put the youtube link up at the Norcal facebook site. All part of the process I guess

I'd hold full throttle and it would be very sluggish before suddenly kicking in after a few seconds. This naturally sent me flying at inopportune times. I managed it mostly until the last minute when it sent me hard into the boards. I ripped the entire rear end off the car, and amazingly the spring from the shock was actually on the axle after all the parts landed.lol. Lost a tire. Cracked the chassis. Broke the shock. A good time was had by all.

Sounds like a bad sensor wire or a sensor board.

definitely sounds like a sensor wire. if you lost total control of the car, that'd sound like a receiver

What is everyone putting on the king pins to get them feeling nice and smooth? I just built the car and they don't feel like they are catching, but they don't really feel smooth either.
