Help Needed NEU 1527 + MMM

[streethot]

Hi there, I am new to this forum, While I am Reading a lot and everything I can, I am posting this to see if someone could help me........First of all I am outside usa, so parts are NOT available.....:(

My project

Kyosho Inferno Buggy 1/8, many carbon parts, titanium parts, the car is good to go

Batteries, 2 x 3s 5000mah 25/50C Neu Energy

Motor Neu 1527 1D 2300kv

Diff Gear Ratio 3.31
Pinio 14
Spur 48

Esc: Mgm 160A didnt hold much for this application, but I am not sure, because one 7XL Feigao (previous motor) had a failure and the esc was never the same, Fet's were changed but something internal stoped working, programming only using traxxas radio, anyother didnt worked.....so, I dropped Mgm and put a MMM V3 in place, for a time it was really great, but I didnt run on a real track or any challenging place, still it was Fast I ever Seen, so I sold MMM V3 and bought a new one....and went to a small track close to home......gosh.....mmm was on fire......everything melted down like a hell, all conectors inside de esc "unsoldered", if it's a word, so far I didnt came to a conclusion and didnt bought another esc.....

Possible causes of fire:
1) MMM itself didnt hold the motor amps

2) 1 motor cable was not burned, but the cable was not soldered on the 6mm conector.....the other 2 was removed with internal parts of the esc......could 1 motor lead at full throtle melted the esc?

3) Batteries conectors: traxxas conectors, i know i shouldnt, but with LUCK batteries leads didnt touched each other......all melted......

So far, I dont have anyone to sell de 1527 and I will not buy a new Esc until find what I did wrong........any help would be great......

Thanks
