Finally got my lite on the track for its maiden voyage. Snapped the front bulkhead and one of the rear ball stewards sheared off. Oops.

The biggest problem was that my car would become unresponsive to varying degrees sometimes. Sometimes reverse wouldn't work. Sometimes it wouldn't move at all. The weirdest thing was that the steering would work every time. One time I noticed the blue wire came disconnected at the connector. Every other time all wires were connected. The motor wasn't hot and neither was the battery.

Car was super smooth and such a blast to drive. Any ideas on why it'd randomly just brick?

Sounds like your receiver or your esc is going bad, or it could even be your transmitter. You could try a glitch buster and see what that does

I think it'd probably be the esc. I could still turn the wheels and everything when it would stop. It was just forward and reverse.

There also seems to be a lot of static noise when the car is on.

Having just gotten back into this hobby with my own B5M Lite, I have had a massive learning curve with these new computer radios and digital ESC. I ran into almost the same odd behavior after playing with settings on my transmitter and forgetting to recalibrate my ESC. Limited throttle, occasionally going in a slow reverse with throttle in neutral position, others moving at a slow pace forward with throttle in neutral. A couple other times the ESC would not go forward or back, I thought I had screwed up my almost brand new ESC. After tinkering and thinking about it way too long, it finally dawned on me I had played with end-point, throttle and brake curves and had not reset the ESC to see these new beginning and end points. I would try and recalibrate the ESC and you should be ok.

For you folks that are new and having problems, don't hesitate to ask for help from people at your local tracks. A lot of us enjoy helping others at the track...almost as much as the racing itself.

One more question...I can't seem to get any punch out of my motor. There is just no power and I can barely clear a double if I carry a lot of speed around the corner and take it wide. Esc is on blinky, no timing. I have a 2s lipo. I feel like it should be faster.

If your ESC is a juststock, try taking it out of touring car mode. Otherwise, it is a 17.5, power is limited. Are you direct wired from the ESC? Gearing? Timing? Rotor size?

17.5. Everything is stock as far as the gearing. There's connectors from the esc to the motor. No positive or negative timing. Esc/motor are both dynamite platinum. Should I try smaller gears?

Haven't used a heat gun but when I go to marshall my car ill give it a quick touch and neither the battery nor the motor is even really warm. Maybe a little heat but definitely not overheating.

Motors normally come with a more mild timing from the factory. You need to turn them up a little to get some speed out of them. By looking at that motor, I would guess you need to turn it up 2-3 tick marks on the motor. And maybe run 72/30 gearing to start with

Ok. Ill try that. And I'm assuming I need to change the esc? Or can I have a few degrees of timing and leave the esc in blink mode?

motor. leave the esc alone, once the punch is set to 100%
