MGM Low Voltage Cut Off - Owners READ

This is my story:
- Problem 1: First I had a 12018 (3.14) that does glitch all the time (instant braking while accelerating or brake all the time).
- Solution 1: MGM changed it for a 9032 (3.21) (paying the difference :) )

second part:
- Problem 2: the new 9032 accelerates while I'm trying to brake, but as you know only with 4 or more pole motors, with feigaos the esc worked perfect.
- Solution 2: sended the 9032 with a align 600xl motor to MGM to show them the issues.

Today I have receibed my REPAIRED MGM 9032 (3.22), MGM told me by e-mail:
"Problem was in defective processor. Rare case"

so... its not the problem of radio, receiver, battery, connectors, motor, etc... it was a defective component of the esc, so...

lutach, you have to send it to them, tell them my case, because it seems to be the same problem. This esc seems to work ok, it brakes PERFECT with the align 600xl motor, feigao, and neu motors :) this is 3.22 firmware.

If you have any question let me know and I'll asq you.

This weekend I'll test it to see if it's perfect or don't work perfect.

I just tested mine and I too was getting a surge when I went from throttle to brake. I then did the "AUTOTUNE" procedure and the problem went away. I then used my USB_Com and hit the default button to see if the problem came back, it didn't. I then tried a few different settings etc. to try and reproduce the "surge when braking" and couldn't reproduce it....
Not saying doing the "AUTOTUNE" will fix everyones problems but it maybe something for people to try before they send off their controls.

Cheers Andrew

I did it (autotune), but didn't work ok, I did all the test you can imagine and doesn't work.
My issue was a deffective processor, not the firmware, I suppose they upgraded my esc to have the latest software, but tue "accelerate while braking" seems to be a hardware problem.

All people that has this problems contact with mgm, and do all the tests that they tell you, they finally find a solution, (with me was about 3 escs and 3 months off nightmares) BUT FINALLY...
all the tests I have done with 2, 4, 6 and also 12 pole motors are OK, the accelerating while braking issue has dessapeared. the esc arm ok all the times (before I had to power on, off, and on to make it work :( )

and.... Countryhick... don't send the esc to mgm if you can do some tests, it's fustrating to not have the esc at home and don't know when will be at home and if it will work ok or not.

Today I'll test my mgm 9032 in my crt with 10s a123 :)
I'll let you know.

and.. sorry about my bad english

I didn´t manage to update my ESC with the MGM Flasher 1.0. What did you do after the update successfull window ?

Attached is the English pdf for updating the firmware on MGM controllers ver. 3.2_> .
