MGM 16018 (possible 16024) - RC-Monster Forums

BP-Revo · **MGM 16018 (possible 16024) -** 10.15.2007, 11:59 PM

Ok, I've just recently finished my CRT .5 (which is awesome). I promise a full write up with pictures and video once I get her completely dialed in, but for now you guys must wait.

Anyway, running the little .5 around has given me a dying urge to run my G2R (and try out these 4500mah Evo30 FlightPowers that are sitting right behind my keyboard).

Anyways, the G2R is somewhere between 9 and 10 pounds, and has a 1940/7 motor. I'll be running 4S (for now).

For the ESC I had been waiting for the MMM (and was thinking about using a MM in the meantime) but I'm afraid the 1940/7 is gonna be too much for the little MM and I'm dead tired of waiting for the MMM.

I've been hearing good things about the MGM and want to get your guys' takes on it. Is it easy to program? Does it run well/cool/without issue even when used at full specs? (like running 6S on a 6S max ESC)

I plan to get a 16018, since I plan to run just 4S on my G2R, but I need a 6S capable ESC when I run my G2R at the worlds fastest challenge next year, and the 16018 is supposed to handle 6S, which is good.

However, I also have a crazy idea of running 8S on a Neu 1521 in my G2R and seeing what that will do, as to where I will upgrade to a 16024.

So, my questions are just on how the MGM's are in general? How do they run? Do they run fine even when driven hard at full voltage capacity?

Thanks

MGM controllers I think are great. It will be a perfect match for the 1521.

What about when running 4S on a 1940/7 and running it hard (like racing)

Will it hold up, especially when rated for only 120 amps (as compared to other controllers which are rated more)?

Also, what does it mean by "opto" under BEC?

I assume I need an external BEC

I have pushed my 16016-3s hard and the controller stays cool. I even had cheap brushless motor go bad and the controller handled that as well. The MGM will deliver smooth sensored like starts with any motor you throw at it.

So far I really like my 9032 running on 33V. The only complain I have about the controllers is the braking and reverse. Forget about reverse.

The programming is not to bad once you understand it. The 16024 is a monsterous controller and will handle just about anything. If you are really looking for crazy power, I'd just go with this one if you got the $$$$.

I don't see why you wouldn't run that LMT on the MM tho, esp on 4S. Many have ran that and hotter XL motors on the MM and its fine. I've continually sent 120A surges through mine for over a year and its been fine. I even used my 8XL/MM on 4S at the RCM bash and it held up great over the 10min mains. I also saw several setups using the MM w/ a 1950 and they were kicking arse.

If you have an ET, hook it up, run it around a bit and see what it does, being nice to it until you have confidence of course.

I'm going to have to agree... My MM took a 7XL on 5s2p A123 geared for 45mph no problem (you saw it). It did require a fan, though, but that's not too surprising (considering how hard it was pushed).

Lehner 1940/7 would be no problem for the Mamba Max! I run one myself, never a problem and smoothest combo going. If you don't plan on running any 4 pole motors, it would be the best choice (better than MGM) IMO. I do run a MGM 16024 too (different rig) and it stays very cool

go for the MM, BP. save yourself a couple hundred bucks for when you plan to go HV.

BP-Revo · 10.16.2007, 06:13 PM

I guess I'll stick with the MM for now, since I'm on the tighter side right now budget wise...

I'll go ahead and put one up on order (they've been out of stock for quite a while now...)

If I WAS to get an MGM, I'd probably end up getting the 16024. I'd never use more than 8S (since 8S is two separate battery charges on my charger as it is, since it does 4S max), so I have no need for the 10S capability, though Mike did say that its safer to run slightly under the limits of the ESC (like 7S max on a 8S controller) if you plan to run hard, since voltage spikes under braking can push the ESC too far.

When the time comes, I'll make my decision for that...

Once my Castle BEC gets here, I guess I'll throw my MM into my G2R and give it some test runs. I'm undecided as to whether 4S should be enough for my G2R. Logically, I think it should be, since it is a track vehicle. However, the other side of me keeps whispering 5S so I can have a boatload of power sitting on the side for when I need to pass a certain someone on the straight.

Later on when I have a good bit of spare cash, I will do an HV project. I already have one in mind. It will involve disk brakes, 8S, a 1521 Neu, and probably an extended chassis. When the time comes, I will work very hard to achieve PERFECT weight balance (and by perfect I mean no more than a 10g difference from right to left, and no bigger than 2% front and rear).

Thanks everyone - I'll do a writeup for my CRT .5 ASAP, but I've been busying myself with integrating mechanical brakes on my G2R (more specifically, using the new ventilated and cross drilled Revo front brake).
