In Search of the Baddest ESC...
 

i have recently built a Losi 8 Tekno RC brushless conversion with a 1515 1.5F. I started with a MMM which died after 15 minutes of running. So i talked to the guys at Tekno RC and they recommended i run the MM with a BEC, which is what they all run apparently. So i hooked that up yesterday and had it on 5 minutes when i gave it a little juice the ESC blew up and send flames and sparks 3 feet in the air past my head.:surprised: Close one! So now i have on another MMM that is modded this time with the fan removed and the top casing cutoff so the heatsink is exposed to stay cool. I ran that last night in races all night and it has held up so far. Stayed cool to the touch without the fan still. Anyway, I have heard good things about the MGM ComPro controllers and Mike gets some in real soon but I just saw an ad in RC Driver today about Novak's HV Pro that is completely redesigned and for 1/8 brushless conversions. Does anyone have any experience with this ESC? I am going to be building a 1/8 truggy brushless and want the best ESC out there. is this new Novak worth considering or should i just go straight to the MGM?

First off, welcome to RC-Monster!

The first MMM that died could have been a fluke, which many others have experienced. The MM, well, that's a bit tougher. If your new MMM is doing well, then you may have gotten lucky :yes:.

MGMs are nice controllers when it comes to hardware, but in terms of software they are a bit lacking IMO. And getting service from MGM isn't the fastest/easiest since they are in the Czech Republic. Some really do like the MGMs, though.

As for the Novak, you'd have to use their motor pretty much. It's a sensored ESC, and must be run with a sensored motor. But comparing this ESC to others (not even mentioning the others) it is sub-par IMO.

Losi also have new ESC/motors available for 8th conversions. could be worth checking it *shrugs*

thanks for the input. yeah, i am hoping i got lucky on this one MMM. i saw the poll here in the forum the other day about the MMMs and it looked as though it was about 50/50 for those who had failures and those who had successes with their MMMs. i have heard that the version3 MMM should be out in a couple of weeks and everyone is hoping it will have the kinks worked out. we'll see. of course, i will put my faith in castle and be buying one of those when they arrive.

i actually have one on back order with A Main but after some testimonials i have seen online it sounds like they are dying down within minutes also. i think i am going to hold off on getting that one unless i start to hear some positive feedback first.

I would either keep sending the MMM back until they get them perfected, or buy an MGM. I'm running an old 16018 in my Muggy and it's pretty good. I like the feel of Castle controllers better (then again, mine has rather old firmware on it) but it handles my Neu on 4s/5s fairly well. I'm looking at getting another controller for my Muggy (putting the 16018 in my Hyper) and it has come down between a MMM and one of the new MGMs.

thats what i am thinking. like i said, that modded MMM is holding up so far but i am thinking i still might have to buy a MGM. i have a couple of other BL setups i want to build and if the MMM lasts i will have use for it but it sounds like the MGMs already have their kinks worked out. although, when i told the guys at tekno i was going to buy a MGM they recommended i wait 2 weeks until version 3 of the MMM comes out and save a few bucks. who knows, if V3 is perfected then the MMM would be a sweet setup. i love the 6.5mm connectors on the MMM. BTW, does anyone know what size wire is on the MGM controllers? is it at least 10 ga?

The wires are 10 ga. They hold up very well under heavy amp draws.

good to know.
