OK somes news on the MGM brake.

The brake on this controller is a piece of scrape:whistle:

I'am not able to have a linear braking. Some times, when i touch the brake just a little bit, the controller lock the wheel immediatly and the back of my truck raise in the air and fall on it's lid, and other time, when i touch the brake, the controller start to give full trottle:surprised:

The rest of the controller run very good, it's smooth, it run cool, but the brake is a dump:eyes:

I've try to upgrade to the 3.23 software, but the controller seam to not want to load it, i've try twice to download it, and both time, the download process was succesfull, but when i connect the controller to change somes parameters, the version is still the 3.21. I've try to run an autotuning, but don't change anything.

As soon as the MMM v2 will be in stock, i'll buy it for sure.

I can't understand why a $300.00 ++ controller can't have a progresive brake in it. And i can't understand why it give trottle when i touching brake. I've try to reinitialise the end point on it (full trottle, wait for 3 bips, full brake wait for 1 bip and neutral wait for 2 bips), but nothing to do.

I don't know if you can immagine, but when i run at WOT, and i try to give a little brake, and the controller decided to lock the rotor.....:surprised: ouch!!!!1 the drive train:oh:
And on other side, when i'am near an obstacle and i want to brake and the controller give full trottle, same thing, ouch!! the front a-arm:no:

A fellow RCer sent me an e-mail asking about an issue he was having with his MGM. I was kind of thinking and got my MGM8012 and tried my JR R-1 with Spektrum to see if that was the problem. Well it was. MGM seems to have difficulties with 2.4ghz radios. My Airtronics M8 (FM btw :lol:) works fine with the MGM8012.

:oh:Maybe... I'll try to find somebody here who have a standard FM radio and try it.
If all goes fine with FM radio, i'll run with that and keep my Futaba 2.4 for my baja.

This is the e-mail the sent from MGM to the fellow RCer:

"some of 2,4 GHz RC equipments use "HRS" modulation. Older controllers don´t know this modulation, checking signal from receiver, and no working.

-Please, try again programming min., max. and neutral throttle position. When controller will don´t work aftter this, necessary is send your ESC to upgarde SW to us. Newest ESC working with these RC equipments without problem."

Keep trying to get the new firmware loaded to your ESC. The issue might have been fixed.

I've send my controller to MGM last winter for the SW upgrade. Now i've try to run it in HRS mode and in normal PP mode, and nothing to do.

I don't know why i've the succesfull message when i download the 3.23 SW and as soon as i return on the controler framework to read data, it's always the older 3.21 version is shown:neutral:

search the forums here others had problems updating the firmware

Yes, i've read all other post about that, and not able to have a clear and precise answer:whistle:
So i'll make my own test:wink:

Hope you manage to upgrade your software, sure your MGM will work fine when you do!

I've read loads of negative posts regarding MGM's which really put me off buying one, but I recently took the plunge, and bought a new 16018. It's honestly one of the best controllers I've ever used.

I have 2 MM's, had a Quark Monster, and an MMM which is being repaired, and the MGM has (in my opinion) been the best. It runs really cool, (I bought the model with fans attached) is easy to program via the pc, and has an incedibly smooth start up with Neu motors, right up there with a Quark. Yes the MMM, has more features, and an unbeatable price, but new MGM's with the latest software are great controllers!

I know, appart the brake issus, i realy like this controller. But i don't understand why i'am not able to download the 3.23 software.

Which version did you have?? 3.21, 3.22 or 3.23?

I have the latest 3.23 software, and apart from having to set the throttle end points on my DX3.0 to 125% it's been very, very easy to set up.

If I get some time at the weekend I'll try and read up on upgrading software, as you know the instructions aren't exactly the easiest to follow, lol!

I'm sure with the amount of knowledgeable people on this forum someone will be able to point you in the right direction, hang in there!!

I thought someone in another thread had the same upgrading problem and figured it out (not sure though).

With the old software (3.04) on my 16024 I had probably seen every problem that others have experienced. I managed to get things working with trying different set ups and returning controller to factory defaults and reprogramming to radio as if new controller. Even when it did work "right" the brakes were not consistent and reverse was unusable. Now with the version 3.23 on it everything works as it should; reverse works great and brakes feel much more consistent.

Nothing to do, just try 5 time to download the 3.23, all the download process go very well, the download window say "device updated successfully".

I disconect the USBCOM+ from the computer, replace the CC_03 cable by the CC_02 and restart the controler v1.27 to gona see the parameter in my controller, and the version still the older 3.21:eyes:

FU..

lolll....its time for the mamba monster maxx:lol::mdr:

did you disconnect the batteries to the esc and restart the computer before reconnecting?

No:oh:
I've only disconect the USBCOM++ from the computer, put the switch on the controler to "off", reconnect the USBCOM++ and put the switch back to "on":neutral:
