ESC in flames

[riverat1540]

my guess is the high amp spike as well. my muggy just blew a mmm3 on 6s running the 2200kv neu 1515/1y tying to pull wheelies at high speed. that draws alot of amps with the heavy losi's when u push them hard under alot of voltage. but with your gearing im not sure, i was geared for about 50 when i had my problem on 6s. motor and battery temps were also fine when it flames up.

Georges told me for the car ESC he was going to make some changes specially with the PCB. I did some tests with the 6S 120A and had to add a bigger heat sink and a fan.
