PLEASE HELP ME!! (pick out setup)

[JThiessen]

I think you are looking for a technical excuse to buy yourself an RX-8. Nothing really wrong with that at this point - we have all done it when something new comes along. I'd just hate to see you posting on here in two months with the same symptoms on your new system. I too am tempted to come up with a reason to buy one of them!
You have been given many examples of similar setups that run the way you want yours to, I think maybe the key is driving style as you seem to run yours somewhat different than most of us. I'm also suspicious of when you stated it really is dependant on ambient temps. Unless you are running in 100+ degree temps (and on hot pavement) for an extended period, it shouldn't put your system into an overheated state. I havent re-read the thread to check this, but how well is your body vented? Maybe its something as simple as that? Try doing a few runs with the body off and measure the temps.

Like I said in my pm to you, my Flux runs very well on 6S, and its about as close as you can get to weight and motor set up to your muggy, and its geared for about the same speed.

I'm sort of in the same spot as you are. I'm setting up a HV Muggy for about 35-40mph. From the beginning I was having a lot of temperature issues caused by high amp draws. I switched from a 80mm medusa to a Neu 1521, and still had temp issues and high amp draws. The Muggy would still fly though. I even test ran a 60mm medusa in the Muggy, and it would still fly. Like someone stated beore, these brushless motors will do about anything. They'll just pull as must amps as they need and are supplied. Small motors will heat up with these amp draws and larger motors will stay cooler.

I rebuilt my diffs a few times to check for any binding issues. I didn't find any issues with them at all. It took me a few months untill recently I found a setscrew was missing in the rear right cvd. The pin in the cvd had come out and was causing some serious binding. Now the cvd is bent and useless. I'm waiting for some new cvds to see if my problems are resolved.

I was told in this forum a few times I probably had binding issues. Just took me a while to find them.

Also, I found the eagletree datalogger was a big help. really lets you know whats going on in your setup. Probably a better investment than getting the RX8. I have recorded a high of 4000watts (geared for 40mph and with binding in the drivetrain).

Just try a new battery... Might cure all of the esc heat issues.

You're right; sort of. It's not that I'm looking to buy the RX8; I'm looking for someone to tell me I shouldn't, and for what reason. I'm DONE with the MMM! I suppose I lack the patience of others? And don't worry, if I'm posting about the same crap in 2 months from now with the RX8, NASA's telescopes are gonna see my Muggy flying into outer space after I punt the damn thing!

My body is not vented well; I can't keep a working MMM long enough to start playing with that stuff. It does need to be vented. Temps aren't too different with body on and body off. Also, I can't comment on how much ambients have truly affected my temps, as I rarely have a working MMM. In 12 months of initial ownership, I only have maybe 10 packs through all 5 or 6 controllers.

And we'd be hard pressed to give any valid reasons to not get that system - looks great so far. I've seen your frustrations with my B'in Law and his HV system - its hard to keep him patient, and help him keep his costs down. It's definitley very frustrating to have gone through the issues you have. Hope it works out....
