Another dead Monster?
 

I have been having problems with my Monster cutting out momentarily, then going back to working fine but the last time it cut out it wouldn't move. When I hit the throttle the motor makes a chirping noise and the rotor moves a bit as if it were cogging really badly. Does it need to go back to CC?

First, check ALL solder connections...then check the wires on the mmm plug which goes into the rx. Also, make sure that the motor leads are all good and tight.

Also, check the switch. I had a prob. w/mine and ended up wiring it together

when i was testing the direction of my motor one of the leads lost connection, it did the same theing chirped a bit, cheack your motor wires

+1 on the motor wires....one of my solder plugs got loose after i nosed into a jump....same thing cogging and chirping....

youre missing a motor phase.
be cearful, the MMM's startup algorithms are different to other ESC's, they start with a lot of power untill they get EMF feedback from the motor at which point they finish their startup phase.
becase there is a missing phase it trys to supply the startup current for longer and this may cause it to overheat.

i think this is correct...
but i do know that somewhere down the line you are mising a phase :P

I'll check to make sure the plug is still connected to the PCB, but it died after some hard braking :neutral:

EDIT: It's not even moving the rotor much, if it still had 2 phases it would twitch more.

I checked over all the connections carefully and tried some other batteries and it did the same thing. It just sits there and screeches, I guess I need to box it up and send it back :diablo:

That sucks man sorry to hear.

sounds like a good excuse to buy a RX8 combo

Thanks. I screwed up a Neu motor a few months back and need to ship that back as well. I guess this gives me a reason to get up and ship back the Neu before the warranty expires (hopefully they'll warranty it, but I'll pay to fix it if they need--my fault it died).

What? I can get the MMM fixed for the cost of shipping vs. $335 for an RX8 combo, no thanks. I've got a very good motor in my Muggy and wouldn't want anything else (except maybe that CC 1518 motor) and the MMM is a good ESC.

today i got the same problem.
will castle fix this or send a new esc?
how fast is castle for warranty repair?
i have to send it in from germany.
