Yesterday i experienced an esc cut out, while flying my e-converted raptor 50 titan se.

Actually, this has happened before on a Trex 550 with a CC Ice 100, but that was due to a capacitor being broken (Only god knows how it broke).

This time, while doing some trimming adjustments, suddenly i lost power, and tried a not so succesfull auto (Low altitude combined with rough terrain resulted in damage).

The log shows nothing strange, at least to me. You expreirenced pilots, bother to take a look, and check something that i ve missed.

i have to mention, that i had control over the heli, until impact, batteries were ok reading over 4,00V, rx battery was also ok. Capacitors moves a little, but i don't think they broke this time.

Forgot to say that headspeed was governed, if that matters.

If you don't feel like flying, then don't

Looks like your ESC went into throttle hold at around 264seconds when the throttle input went below 1ms. Maybe it happened while you were doing your trimming adjustments?

I have talked with Clint at Castle since this incudent. He noticed the same thing as you.

Probably i had a signal loss, thus the failsafe engaged and zeroed the throttle. Otherwise, esc did what was told, and immediately after the signal loss, power came back, but with soft start just before i hit the hold.

Have to check on the rx now and its power system.

Thanks Fong
