Default Looking for help with Castle MMM ESC

I'm trying to troubleshoot a friends Savage Flux. On six cells it has started acting oddly. When at at dead stop, pull the throttle to a set amount and hold, truck will start moving slowly for approx 2 sec then instantly go to whatever throttle position you have held. I've tried updating firmware, changing start power, reset to defaults, even swapping my mmm out of my revo. My mmm acted the same. With only one batt hooked up (3s) it worked fine. I'm considering it may be the batts, but it happens at any throttle position and does not happen on only one batt. I'm running out of ideas. My friend states it just started happening one day. Batts are the same since day one. Any help would be great.

What kind of transmitter are you using? Have you attempted to troubleshoot this aspect?

i had a MMM fry because the motor had siezed up. i guess trouble shoot one thing at a time and narrow it down to what you think may be the cause. if it is the speed control CC has great customer service.

Any chance you could see what the esc's LEDs are doing when its moving slowly? If something going on with the MMM, LEDs may be telling you what's causing probs.

I should have posted about the radio. Its the stock pos HPI am radio. No setting that could cause this behavior. Like I posted I swapped in my MMM and it did the same. They are on the current firmware with default settings. I didn't check the motor. If you are moving already it acts normal. Its just start up.

I'm hoping one of the castle crew catches this one and can add some input on settings that can cause this.

well it's obviously the motor if your speedo does the same thing. is it jerky at all when it's doing the slow start thing? could be the esc isnt getting enough feedback from the motor. maybe solder joints on the motor?

It does not do it on 3s only 6s. I would think that eliminates the motor.

Did you try a stutter stopper or an external BEC. I know with todays servos alot of esc's are having problems with stuff like that and alot of times its due to the receiver loosinga little voltage and causing alot of the problems.

Castle has said they will, but prefer that you go thru HPI - ques was asked on their thread on RCMonster.
