It goes forward fine, but when you apply the brakes it accelarates forward instead of braking.

do you have another motor around? Try that to see if it clears up the problem, I had that happen and the motor was bad.

Also, try to auto-tune, but you may have already tried that.

The motor is not bad. I'm using it without an issue with my Sculze 40.160.

Have you try to change the neutral zone on the controller? Try to put an higher number....Sound like you r controller don't see the neutral zone between the change from fwd to rev.

Yes, that was one of the first thing Mr. Grisa asked me to do. I might just send the controllers to MGM and get the latest FW.

Why?? you don't have the new SW in it now?

Got it a while back.

I have some news to you and all mgm users that have this issue, it accelerates when you try to brake, mine only did this in4 or more poles like neu or align 600xl...

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.

Thank you. I will send them all then to get the new 3.22 firmware.

Do you know if the problem will be solved by just updating to the latest firmware? Or is everyone that has this problem [quote] "Problem was in defective processor. Rare case." I have just got my stuff back from MGM and don't feel like sending it away for a few more weeks.

Cheers Andrew

I just recieve my MGM back from Grisa with the 3.21 SW in it, but not try it yet. What's the difference between the 3.21 and 3.22 SW?? Can i download the 3.22 on theyr web site?

Yes you can.

For those that have firmware 3.20> you will need to download 2 small programs from the MGM website CLICK HERE. You will also need a CC_03 cable and a USB_COM ver. 3.__> .For some reason I couldn't download the english version of the flashing instructions. If you can read Czech you can download THIS one. :lol: I managed to work it out any way and have upgraded my speed control from ver. 3.21 - 3.22 .
I am still yet to try it out but will post back when I get a chance.

Cheers Andrew

Hi Andrew, I managed to download the programs from that website and I went thru the software update process.. Software says that Update successful but when i restart the controller it still shows up as 3.21. Any tricks I need to do after the 'Update successful' message to get the new firmware active? Thanks

Are you checking the version number with the flash software or the normal CC_02 cable and USB_COM? I checked with the CC_02 combo and it said ver. 3.22 . I did notice on the flashing software that the version number wasn't 3.22. :neutral:
Regards Andrew

Checking with the Controller software and CC-02 cable and the version is still 3.21! After the 'update successful' message, I just shut-down the software and restarted the controller. hmmmm..

I just ran through the whole process again and mine still says ver. 3.22 . It may just be me but I think every time you swap from the flasher program to the controller program I had to remove the USB cable from my computer and then reinsert it, otherwise the controller wouldn't show up?????
A couple of things to check

1. What ver. is your USB_COM?
2. In the flasher program make sure the drop down box is says "Update device through USBCom" .

What ver. of windows are you using? I'm still running XP. (don't know if it's a problem but thought we might be able to eliminate a few possibility's)

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.... :neutral:
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 :oops:

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

English UPDATE pdf
 

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

Yuppp, followed that exactly and still the controller software reports it as 3.21. Wonder why....

Try disconnecting the USB cable from your computer then reinsert and check again.

That does not help ...

Yup, same here. After restarting the controller and replugging the USB back in , the old version of the software is still reflected. hmmmm

No issue with updating to 3.22. on my 4412-3, now 16018-3 to go
Did the update, unplugged USBcom pro PC! as mentioned in the manual, changed CC03 for CC02, replugged USBcom, launched controller and 3.22 was there

Wallot, did you repower the controller after the update and before switching it to the cc02 and controller software? Thanks

yes i did repower the ESC

Hey quick question... Can I safely run 6s lipo on an MGM16018 using the built in switching bec?
I have another bec i could use but I would rather just use the built in one if it doesn't fry the MGM. Thanks!

yes you can. mgm has a switching BEC, but why not to offload the ESC using external BEC that takes no space and requires simple soldering :)

Because I am a tight wadd and would like to sell the BEC! :lol:
I guess I better just keep it and use it to be safe.

For the $10.00 you'll have for it, you must keep it:lol:
