Getting a little bummed out

[nitrostarter]

How do you guys test a motor without a ESC to make sure its ok? Its still strongly magnetic and doesn't smell funny. Any suggestions?

[shaunjohnson]

put 6v across each of the phases to see if one is properly fried, just jab it.
or i guess you could mesure the resistance of each phase and look for a funny number.

i guess i have been really lucky this year, this is the first year i didnt fry an esc

Are most of the failures still happening on 6S?

A buddy has a V3, bought Dec. '08, runs 4S and no issues.

I don't think I've ever seen a MMM fail on 4S, have there been any?

Mine was on 4s Hyperions 5500's with a Neu 1515/1.5D/F in a Emaxx geared for 45mph. It ran great for about 8-10 runs since I built it.

i've fried 5 mmm's on 6S. what's weird is that i've only ever fried them in my G4, and i gear it very conservatively.

but 5 failures, 4 were blown caps and one BEC.

the 8ights on the other hand are my speed vehicles and i gear them 43/25. the mmm's have never failed there once. the only difference is weight, gearing and grass. my 8ights are geared very high, they never see the grass and they are much lighter than my G4.

after my last smoke, i dropped the rx8 in it with great success.

All my trucks are and were geared conservatively when I had my failures (5) and was running 4s in every one. Over the course of 2yrs, so after it's all said and done I guess that aint to dang bad ? I have 2 I run 5s and no problems yet (fat fingers crossed)

What version mmm's were those that failed?

[Bondonutz]

(1)-V1
(1)-V2
(4)-V3's Of all the V3's, one crapped out in Nov last year and the rest this year.

ive had one fail on 5s in my crt truggy and one just fail on my muggy on 6s the muggy it just stopped like the switch had flopped. i turned it off then on and it started to smoke followed by a flame throwing monster, and my truggy on 5s all i did was plug it in flip the switch and and it started to smoke.
