The MGM esc's are great now with the newer firmware.

MGM you say? any specific model? thanks

With that motor, I would probably go for the 22418.

is that because it has 224A continuous? the motor should only put out about 100A continuous, possibly spike to 200A occasionally.

do you know the continuous rating of the MMM or the peak rating?

I just like to be sure the esc will handle it. Not sure about the MMM, Patrick from CC gave some rough numbers in a thread around here somewhere. I think he said they were getting 600 amp spikes in their 70 mph emaxx.

*edit* Here is the post. 100 amp continuous and 800 peak.

o right. 100A continuous isnt actually that much if the battery can do 150A continuous, its kinda limiting the motor. maybe i should go for one of the MGM's, they look pretty capable although they dont have a fan so i wonder how they keep cool...

that is continuous 100a, that is plenty, and then the 800a peak, WOW the motor will not be starving for any energy.

is this one any good do you know?

You can get the MGM's with fans on them, if you must have fans, but they stay pretty cool without. The quarks are iffy on 6s, some do it, some don't, and it seems they are hard to get support for now.

the v2 is all sorted out now so i would get the MMM.

they keep cool due to good quality hardware and design....if you have those 2 things there is no need for a fan, and stay away from a Quark

i have seen afew posts about v2's with the same problems as v1's

side note, will running my 2.5df on 5 cell cause extra heat?

So far the V2 mmms have been okay- only 4 known failures reported.
Your 1515 2.5d is only a 1650kv motor, so it will do just fine on 5 or 6s lipo- just afjust gearing accordingly.

but the 1521 will be better because it has a slightly higher kv rating and its more powerful so i can gear it higher and get better top speed without sacrificing any low end.
with a more powerful/bigger motor, will that use up more battery even though it says it has the same amps?

a 1515 would be plenty of power for you and good luck with your drivetrain you will need upgrades....I get 50 mph with my Revo and that is about as fast as you want to go with a MT

Heh, 40mph is scary enough- you need alot of space and smooth ground to use all that speed... *said the voice of (limited) experience*

nah, when you have an entire park all to yourself... acers of land... you just wanna go as fast as you possibly can. 50mph is too slow lol - 60 minimum!
