As you know from this topic:http://forums.radiocontrolzone.com/showthread.php?t=185631 I have a new RC10B4 Factory Team with the SS5800 Brushless and an XR2i. Well, I set the car down on the ground with a fairly charged GP3300 pack(i had another one just peaking that i was going to run with when it was done). I drove it around for the first time, and after a minute of driving, it stops dead. The steering servo works, but the motor isn't moving.

Drivetrain isnt binding, the lights on the ESC are working, I tried another reciever of the same model, etc.

All the wires are plugged in, sometimes when i poke a wire or two it will glitch. Unplugging the throttle wire from the reciever and plugging it back in gets me a little glitch of the motor. Two different recievers do this.Also, sometimes the motor will work, but in VERY jerky cogging movements, and will only rotate back and forth, then the ESC does a thermal shutdown. The diode gets really hot also.

What the heck could have happened? There is lots of snow on the ground, but the streets are dry, maybe a little moist. There's also a little salt on the ground that they used to dry up the snow the night before.

Anyone got any suggestions?

Sounds defective to me. I would contact Novak. They will hook you up with a new system in no time.

I figured out a bit more about what was goign on. The diode would get very very hot, and it would need to cool down completely before it works again. It happened after a minute of driving. No thermal shutdown, as the heatsink wasnt hot enough.

I was wondering if a bigger diode would help, but my LHS didn't have the diode kit in stock.


Well I took it to the LHS and they thought it was the pinion. I moved from 23T to 19T. I did some donuts in the kitchen and it didnt seem to heat up as much. I'll know tomorrow if it worked or not.

Also while i was there I picked up an XXX-4 buggy today, along with a 13 turn double motor(hand wound by one of the guys at the LHS), and an 8T Duratrax Intellispeed. I got a reciever and am using my XR2i with this one too.

What version of the XXX-4 did you pickup?

Do you guys race 4wd out there ? Class should get going much more this year with the various 4wd buggies out there.
