Is this something I could test just by seeing what the motor does when I use the motor brake? For example are you wanting me to see if it goes into reverse when I hit the brake?

The issue that I have when my controller is set for forward/brake only is when I apply the brake instead of braking it throttles up. The more throttle I give the stronger the throttle up is when I try to apply the brakes. It does this as well when forward/brake/reverse parameters are programmed too. I don't want you to break anything though.

what does it do when you apply forward?

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.

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. 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

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.

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 ?
