I have been running my Savage truck equipped with a Mamba Monster 2 ESC and 2200kV motor (purchased as a combo from Tower Hobbies) for about six weeks and have had no problems with the motor or controller until today.
Less than 5 minutes into my first pack (4S) the truck suddenly went dead. There was no power coming from the internal BEC and the controller itself was showing no lights.
All battery connections were secure, as were all connections to the receiver. Both 2S packs were still showing a full charge.
I noticed that if I turned the power switch off and then on, the ESC's green light and the receiver's power light would come on only for an instant before going dead again. The motor would also begin its startup beep, but would cut off at the same time as the lights. Each time I turned the switch on, it would start up for a fraction of a second and then shut down.
Saddened, I brought the truck back home. When I connected the batteries again on my workbench I verified that the ESC was still not working.
Here's where it gets interesting. On a whim, I decided to see if my Castle Link adapter could still talk to the ESC. I launched the Castle Link software, plugged in the ESC, and it worked! The computer was able to recognize a Mamba Monster 2 controller and read its settings.
After disconnecting the ESC from the Castle Link adapter and plugging everything back into the truck's receiver, I connected the LiPo packs one more time... and the truck fired right up! Throttle and steering commands seem to work perfectly, and everything seems to be back to normal.
What exactly happened here? Is my ESC defective? If this happens again, how can I get the ESC to "snap out of it" without bringing it all the way home to my computer?
