mm and neu ?s
 
How good of a combo is this? i am putting it in a crt truggy and i am not sure how good the two will work, how is the cogging stuff like that i will run 4s.

squeeforever 10.29.2007 10:48 PM

It will probably cog. The MM's don't like the Neus.

mach1stang 10.29.2007 10:53 PM

really that sucks, how about the mgm 160amp controller?

I used a MM and a Neu. I hated the cogging but you can minimize it. In th computer set up for the throttle pull it down at about the 30% mark so that it becomes a smooth curve. This helps but if you want smooth running use the MGM. My 1515/1y 2200kv handles 4s easily. Here are some settings:
settings are:
brake 30%
punch 80%
start pwr low
drag brake disabled
motor timing low

mach1stang 10.29.2007 11:02 PM

but there is still cogging? i had a 7700mm and it would cogg so f***ing much that i hated it.

mkrusedc 10.29.2007 11:27 PM

I never could totally get rid of it that is why I got a MGM.

jhautz 10.29.2007 11:27 PM

The MGM or Quark will run the Neu with no coging. Smooth as silk. I still like the way the Quark feels better when driving it, but the MGM runs cool as a stone. I havent been able to heat one up past 120 no matter what I do.

Either will be a solid chioce with the Neu.

That's weird, usually increasing start power helps the cogging. Higher punch control is understandable though. IMO, adjusting these settings is just a "bandaid" and the MM shouldn't be used with slotted stator motors until the elusive fix is released.

i have heard that the quark needs a cooling mod?

It usually doesn't need it right out of the box. The heat sink does the job, but over time the thermal tape on the inside will loosen and then you will need to do the mod. Kinda sucks for $280... But its still the smoothest least quirky controller out there (EDIT: Up tp 5s)... But for the most part I have my Quarks on the shelf and am running the MGMs now. Just cuz of the heat issues.

BrianG 10.29.2007 11:35 PM

Depends who you talk to. Some people are OK with temps in the 150*F+. I like my electronics to run cool, so the mod coupled with a little extra heatsinking helps keeps temps much lower, not to mention faster/more efficient heat transfer from the FETs to the case.

(Edit: my post was in response to mach1stang, but jhautz typed too fast :smile:)

Thanks for pointing that out. This was my inital settings. Later attempts even with high start power mine Neu cogged.

mach1stang 10.29.2007 11:54 PM

so the quark is good but has a bit of heat to it, and the mgm runs cool, but has a funny feel to it?

squeeforever 10.30.2007 12:11 AM

If you get the settings right on the MGM, people say its the best of the best.

mach1stang 10.30.2007 12:17 AM

what does it do exactly?

jhautz 10.30.2007 01:20 AM

The MGM has quirky reverse/brakes. If you have it set to reverse mode and you are going slowly forward and hit the brakes it goes straight to reverse. Only when its going slow though.

I have been having a quirky brake thing going on lately too. Every once in a while I'll hit the brakes and get nothing. It just keeps going. Not sure why. Its very random and very infrequent, and not related to anything that I can trace. Just a weird quirk of the esc. The other thing with it is it seems to have a very touchy low voltage cut off compared to most other ESCs.

But none of this is very serious, and yes you can "tune" alot of it out as Squee said. And the plus side is gigantic IMO. The built in BEC that can take 6s, The cooooooool running temps are 2 that really jump out as special.

It seems all currently avialble ESCs out there have one or 2 little challenges to work around. You just need to pick the one that you can work with for your application.

mach1stang 10.30.2007 12:33 PM

so it is just the brakes, is it a better choice then the quark?
