We ended up taking coils off and put in a 17 wind regular brushed motor and now runs great, but there seems to be a problem with the box setup.
I just got my XXX-SCT about a month ago and not only did I have this same problem, my throttle never had any variable control. No matter how gently I squeezed the trigger, it would go directly from 0 to 100% throttle. It got about 2 days of racing, 3 x 5min quals + 1 x 8 min main before the electronics completely failed and the truck stopped working. I had to splice solder the motor wires after the very first run because the "inductors" literally melted away. The longest run time it had was 15 minutes during a practice session and I could literally smell the burning electronics as my car drove past the drivers stand. I ran a 2Sx20Cx5A lipo in it, same as 7 other RC cars I own and I have never experienced anything like this before.
Fortunately, Horizon has honored my warranty claim, but now I wonder if the replacement ESC and motor (currently on back order) will also fail...
Has Losi improved their motor since the truck was manufactured, or did I just get bad electronics out of dumb luck?
