MGM 22418 experiences
 

MGM Compro 22418-3 Car / Boat EXPERT+

My experiences so far :

This ESC rocks !
I had a numerous ESCs in the past (including Schulze and Kontronik, both from German manufacturers) for many rc-cars from 1:16 to 1:8. But this one is the best.

Let me explain :
For me it is very important that the controller keeps cool and the motor runs smooth without cogging .

Check your sensorless ESC if it manages to push a heavy car forward if it climbs on a steep hill and makes a short stop in the middle .... (the Kontronik Jazz 80 was not able to handle this situation)

With the usbcom+ you are able to change many parameters in just seconds - I recommend to use the auto tuning function to autodetect the best settings for your motor. I promise that you will find the correct values for acceleration and deceleration for your car!

Another important feature of the MGM Compro is to protect your lipos. (reduces RPM if the voltage drops under a specific value) [as I posted
before in another thread, this may cause trouble if your lipo is not able to deliver such a high current]
In my opinion the "low voltage cut off bug" mentioned here in the forum is a consequence of weak lipos !

Problems :
The peak current values displayed on the pc are not realistic .
Finding the right brake setting is difficult.


I have to say thanks to MGM Compro for the fast delivery and great support (they send me the 6mm MP-Jet connectors - which are able to
handle up to 300 A !!! FOR FREE - these plugs are amazing ! )

Just one question for you: "Are you sponsored by MGM Compro???"
When all others guys here have bad thing to said about their MGM, you'are the only one to compliment your's like that:lol:

I only hope that my 16018 will run as good as your's when i'll recieve it back from MGM.
And for the li-po, i've a Flightpower 25C, 5000mAh, 4s.

The only thing, my controller left MGM in Czeck republic since one week and a half, and never recieve it yet:neutral:

No I am not sponsored by this company but I have a never firmware (3.21) which seems to run very well. Do you have a data-logger ? Check the voltage of your lipo und the highest load ...
I received my parcel within 3 days (to germany)

No ESC is perfect
I can compare my two Quarks and MGM16018.
Both quarks had issue with overheating (fixed that on the second one) but both of them died. One totally, the other just went nuts.

Never had any issue with MGM.

Also quarks had small cogging issue, MGM is as smooth as it can be.

OK thank you guys, i'll hope to recieve my controller this week, i'am in canada, so realy far from Czeck Republick than Germany are.

I hope that the new version will fix the problem, because you know, when we take the decision to pay $300 ++ for a controller, we expect to have a better quality unit than a $125 controller.

Thank you for all your response guys, i realy appreciate all the help that we can obtain here on this forum.

I'll keep you inform about my controller when i'll recieve it.

It's unlikely that I'll try another MGM. I impatiently await the MMM. For the price of the MGM controllers, I expected top notch. Not problems with reverse, brake, and freewheel settings. The BEC in mine burned up after about a week, and then a couple fets went out shortly after. All this running proper gearing with a 4s lipo and feigao 8xl. I was not very pleased with it. My Quarks run hot, but they are easy to program, and the settings always stay after you set them. Even my MM has no issues with the same setup in the same truck.

If this happens I would send the controller back for sure.

Topas, did you run the internal BEC of your controller or you use an external one?

I run the internal BEC !

Could this controller work fine in my car? I have a converted Savage with a 7XL motor, and I have already fried two 125b. The weight is 14.3lb with 16-cell NiMh (sorry, no money for lipos) and total gear ratio is 25:1 (13T pinion, CEN diffs, 1st gear blocked).

Thanks.

I've heard too many horror stories to say anything positive about this controller. I know of three of them that have gone POOF. I know of a couple that never even made it outdoors before they smoked.

A 7XL in a 14lb++ truck is the first problem and it's the best way to fried alot of controller.
Start by change your 7XL by a 10 or 11 XL, and buy good li-po, i know you tell that you don't have money for li-po, but wait and save some $$$, it's worth all the money you'll spend for it:yes:
And yes MGM is very good controller. But it's like any other electronics component, that's not bulletproof.
Lastly, somes MGM have experimenting somes bugs but lots of guys have good result with there MGM and this controller run very cool and smooth.

Thank you for the advice.

I did not believe that a 10XL could be powerful enough for my car. I will try it.

Do you think I should wait for the MMM? It looks very nice...

Thanks again.

I agree with david. I'm not surprised at all the you have smoked 2 quarks with the setup you mentioned. 14+ lbs is a big truck for a 7xl I agree that You need to run a lower kv motor. A 7XL spinning at 43K rpm on a 14lb truck will pull a hell of a load. Shoot for a total motor RPM on the conservative side to compensate for the extra weight that will be stressing the system. A high RPM system and heavy load are a recipie for disaster IMO.

As far as the MGM goes. If any controller can take that load it would be the MGM. They run coolr than anything else out there by far. If the latest software update for the false overcurrent problem does indeed solve the issues some have been having (including me) then it would be a great controller. I would hang tight and pay attention to THIS thread before making a decision on the MGM.
