I ran my MGM controller through 8000 mah of 11.1 volt power in my stampede with maxx tires yesterday without a fan or a thermal. I didn't even check the temp of the controller, but it didn't thermal, so I was happy. I wouldn'y use CA glue myself. they make a substance called heat paste, or heat compuond (or some similar name) that is supposed to heat transfer the heat more efficiently. If anything, I would use this and maybe hold the heatsink on with some shrink wrap(trim heat shrink around outside so the shrink holds it on, but it still gets are over the heatsink). Just a suggestion.

ok, i was thinking bout using some paste to begin with since i picked some up a few days ago.i guess i will figure out some way to mount it.

I wouldn't use glue. I'd use the same thermal grease used for CPU heatsinks, you know that'll transfer the heat since without it your processor would be toasted in a few minutes. Newegg has several. Actually I'm kinda surprised it's not used more than it is considering you want as much surface contact between the heatsink and the part needing to be cooled.
Thermal Grease

just went outside and did a run, the truck ran great for a few minutes, then i started noticing as the battery dropped off, the truck wanted to throw itsself into reverse and drive around. the bats are side x side gp3300's, but they have always had power problems. i am going to go charge me up a new set of my racing bats and see what happens, just wondering if anyone else has had the same problem.
thanks

oh yeah, its just setup in the default "turn it on and go" mode

I haven't noticed this on mine. I don't run in default mode, but that shouldn't matter. It seems like your throttle trim is creeping or something. Strange.

I would use thermal tape and heatshrink, should be much better than using thermal grease and heatshrink. I dont know if they sell them by themselves but if not you can usually get that and a fan or heatshenk for $5. In fact I think they have one at compusa with: small fan, two heatshinks, thermal tape, thermal grease, for like $5. It's package is one of those generic ones, just saying compusa.

Do you have a compusa near you? Or any computer store.

thunderw0lf: Newegg is awsome, my dad and I shop there all the time (spent about $1,000 making a computer).

i have a couple of places near me but i dont really like fans unless i could get a super small one. basically i just custom made a heat sink out of a section of a real radiator. we did a prject at work not long ago where we assembled the small radiators so i picked up a couple of sections, cut them to fit and backed it with the heat transfer paste.

Fans
 

You can also check www.2cooltek.com They have all the fans you could need or want - I have dealt with them before.....

So have you guys found anyway to elminate the braking from full to partial throttle? If this can be elminated I'm going to order one of these controllers tommorow, along with a Lehner basic 5300. If you cant get rid of that I might just go with the Warrior 9918 for my T4, I've heard the Warrior isnt that great but I sure as heck cant afford a Uforce, and I cant deal with the full-partial braking, that'd be a dissaster out on the track.

I just heard here That MGM has got a new firmware revision for the controlers. I'd ask Mike to send in his current supply and get them all updated and temporarily hold sales untill they get back. Otherwise, all the rest of the controlers that he orders will have the new firmware and won't break going from full to partial throttle.

I happen to be out of the 80 amp controllers, so the new ones that arrive next week should have the new firmware. I have the 120 amp version coming as well.
