I just fried my cc p80 esc
may have been esd ( i will ground the boom)
i had just installed a new main gear so i fear the meshing may have been a litle tight. do you think that can cause an esc to fry
(first it cut out at bout 10 feet and then it had trouble spooling up then it sparked and smoked on the ground)

A over tight mesh will pull more amps, sounds that something overloaded the esc. Bummer....

Well not only motor section is always the faulty one. I know many people damaging their controller with too much load on BEC. Modern servos are real BEC killers. This could be also the problem but maybe you have an OPTO version. In both cases too tight pinion can cause very high current peaks in certain flight phases which may sooner or later damage any controller regardless whether 80A or 130A.

i was using a UBEC
the only thing that changed in the helicopter was the new main gear and relocation of esc relative to receiver, I used a 4-6 inch extension. esc at rear of chasis, receiver in front. I don't think it was the meshing anymore, Now I think it may have been because i attempted a restart immediately after the shutdown and the esc may have been negotiating timing or something. I'm lost
