MMM vs MGM 16018, resistance
 

So I have an mgm 16018 on 6s, would I notice a difference if I switched to a mamba monster max? is the mmm any more effecient that I would notice more top end say?

Sounds like
 

Well you said it. Sounds like a good reason for a comparison test with eagletree data for everyone to see. While your at it why not use a MA True 150C rated Lipo and compare it to lets say an equal Turnigy Lipo pack. Then you would be able to kill two birds with one stone, right? It would be interesting to see a direct comparison with these two products. Please share your experience with us.

wo wo wo there!

lol :)

Theres me trying to get out of de-soldering the Mamba from the crt, guess i'll have to do it myself then! :D no eagle tree here im afraid, you'll have to do with "yeh its a bit quicker" or "na its the same"

Lots of people claim Max Amps batteries are poor, even compared to Turnigy. Based on the MA price and the fact they are still in business, I'd have to say I find that hard to believe. But, I haven't tried any MA batteries.

I'm not sure if its faster, But i bet it is more efficient. I run one (16018) with an over-geared lehner 2250/10T in a twin force, on 6s lipo. never once got hot at any time in the run.

On a side note, is there a american distributor for MGM?

How does the Twin Force handle that power? I tried once with 3s and the torque made it pretty much undrivable. Have you modded it or something?

Unless?
 

Unless something has changed MonsterMike did have them in the RCM store.

It was mostly onroad i drove it, due to lack of parts, this was before the re-introduction. This particular truck was bought off Ebay from Promod, Most old school MT guys will know that name. This one has a New era Long wheelbase chassis and a center diff with buggy diffs, seemed to handle the power nicely, but never pushed it. I broke the right rear housing at the knuckle and plan to get it running again. Even with a leaking diff it would slam the wheelie bar hard and run close to 45 easily.

Back to the 16018 though, I was using a eagletree 100 amp micro data logger,and logged a few 120+amp runs with around 2600watt peaks and the MGM never broke a sweat. The gearing was buggy diffs with a ofna diff (I think) a 51 tooth plastic gear, the one used by most strobe slipper setups. I was using a 19tooth Monster pinion on the motor. here is a BrianG setup showing the setup

As you can see it was massively over geared and the MGM never broke a sweat, Most runs were around 5-10 minutes. I wouldn't mind running the MGM's again but the expense and the lack of U.S support make it almost not an option

Mgm compl pro.
 

I have a couple of MGM ESC's myself, but have not run them because of the customer support issues. I started a thread last month about the fact that I am living in Prague now and will be here for the next few years, so I am planning to pay a visit to the MGM shop in Zlin, Czech Republic once our van arrives and we can take a drive out there. I have exchanged emails with one of the owners (Martin) and we are looking forward to discussing the matter to see if this can be resolved. His view on the matter at this point is that they are already doing everything they can from a foreign location perspective, but he is willing to hear complaints and if there is a better solution he is all ears. Our van should be here in the next few weeks, and then we can make plans for the trip. From what I am able to assess on our TomTom GPS this will be a 5 hour drive just to get there so the wife and I will plan an overnight stay and hopefully I will get to spend some time at the MGM shop.

Hey just noticed that there is a "Spell-check" program operating on here now. Way yo go Mike.

I don't own amy MGM ESCs but would love to try some in the future although that comment doesn't sit well with me. "Doing all they can from a foreign location perspective". Castle is in US and I am in Australia. Never had an issue dealing with them. Something was faulty and within 12mth warranty period they would sent me out a replacment free of charge as soon as they receive the faulty item. If MGM aren't doing that then I doubt that they are doing all they can. I know that those are their words Jerry so not having a go at anything you said. Just pointing out that they might not be doing all they can.

I do understand.
 

Believe me I do understand. This is why I have plans to go out there and sit down for lunch with Maritn and chat about this. Still you have to see things from their side as well. They are not in the volume business like CC with shelves full of a line of ESC's just sitting there for warranty replacement. They are more of a specialty buisness and fabricate a lot of custom controller designs for specific customer needs. So when a warranty issue appears on their door step they take it into the troubleshooting lab and check it out thuroughly and try to determine why it failed and what was at fault. If it was a design, software, or hardware fault, then a warranty repair is performed on that unit and it is sent back to the owner free of charge. If it is a personal error on the part of the owner a communication is sent to resolve the matter of payment for repair & shipment before it is done. Once payment is received the repaired ESC is sent back to the owner. They are protecting their investments just like any company would. Yes it is a bit more complicated than what CC does, because the circumstances are different. CC has a whole inventory of warranty ESC's standing by and in order to save time they wave troubleshooting in order to keep things moving more smoothly, because they are dealing with a high number of electronics in comparison. They give things a general look over and make a professional judgement call one way or the other and deal with the situation at hand.

I do not defend MGM in any way. I am just stating the obvious with the information I have been provided. I hope this makes more sense to you now. The fears you have are the same across the board for all of us, but what can anyone expect them to do? I will share my experience with everyone in here once I get to have my visit with the MGM owners.
