need help for my MMM 2200kv
 

hi there guy, i got a TRAXXAS SLASH 4x4 PE with a MMM 2200kv system and a 11.1v 4200mAh lipo with it....the problem is that i try to calibrate the 3PK...first i turn on the transmitter, then plug in the lipo and turn on the MMM, but nothing happen....except the servo is working, the MMM lights are all FLASHING and got a beeping sound every 2-3 second.....just wondering if any of you could help me to fix this problem??? THANKS ALOT

sounds like its not bound to the receiver

Flashing all colors = speed control is not receiving a valid signal from the receiver. Usually indicates the receiver wire is plugged in backwards into the receiver; also happens when speed control has accepted a calibration setting (throttle, reverse or neutral) and flashes/chimes 4 times before moving to next calibration point; or problem with throttle channel on receiver.


Check your setup -- looks like the controller isn't receiving a signal from the RX.

Could simply be the speed control is plugged in backwards.

guys, I already tried everything and seems like still not working....now I'm still waiting for the reply from CC and will see what's up with the MMM, anyway, THANKS ALOT FOR ALL YOUR TIME AND HELP!!!

The ESC is plugged in the correct way on the receiver because the steering works, if it was backwards then you would not get any receiver response; unless you are using an external power source to the receiver.

Does it still hook up to the Castle Link? Never hurts to try a firmware update, but I doubt it will fix the problem. Has the speed controller ever worked properly? If so, then what happened between when it was working and now? Was it working when you put it away, pulled it out again and now this? Have you changed radios recently? Taken the car apart and reassembled? Had a really bad crash recently? Usually things like this don't just happen and causality is key to finding and fixing the problem; that being said, sometimes things can just happen and there is no explaining the occurrence.

It sounds like the throttle channel may be bad on the RX/TX. Easiest way to test for this is to swap the servo and the ESC in the receiver; meaning put the servo in the throttle channel and put the ESC in the steering channel. Power up the ESC as normal and see if the throttle trigger controls the servo. If it does, then the throttle channel is working properly and the problem is probably with the ESC; if it does not, then you have yourself a radio problem and you can dig into it from there. If the speed controller continues to have the same issue in the steering channel, then it may be a problem with the speed controller. It could be an issue with the orange wire on the ESC's receiver lead; if this were the case though, I would expect you would have troubles using the Castle Link. Trying a completely different radio system (transmitter, receiver and servo) is another way to eliminate the radio as a culprit.

If none of the above methods resolve the problem, then the only solution would be to get the controller sent in for repair. Please let us know how the testing goes and we'll see how it works out. Let me know if you have any questions or concerns.

Hi Thomas, I already tried all the ways that you mentions but still don't work...all the lights flashes and got that beeping sound every 2-3 sec....you mentions about sending the MMM 2200kv system to you guys for repair. I kind of DON'T WANT TO DO THAT, cause I orded it from Tower Hobbies, as soon as I received the ESC, I just let it sit in my office till last week and installed everything in my 4x4 PE(MEANS IS BRAND NEW OUT OF THE BOX AND NEVER USE). Well, I'll take the whole thing to my friend's hobby and see if he's able to help me or not first, then I'll think about sending it back either to Tower Hobbies or you guys...anyway, thanks for all your time and help, will update you later.
P.S. I think the ESC do link to the CC computer Software cause when I plug in with my computer, the software do show the ESC name.

try putting the throttle to reverse on your transmitter and recalibrate

all the radio set up are DONE DEAL at the first place...
