It flew perfect, a regular patrol flight 500m radius. I heard one short beep from my TX, at the same time my hex are fallen like a rock. Try to throotle up and return home but nothing.

Still wandering..
Really appreciate for any info or help to read super X black box

I always fly with 2 battery.
No fix wing flyer are dare to fly in that area because of many frequency interference. Many of them are crashed, only on certain area

You were flying in GPS hold mode then prior to the crash you were going in and out of manual mode ultimately into safe mode, if you were not applying switches on your radio it could be the interference you mention, however your battery(s) also took a momentary dive that would not be a result of external interference, your motors need attention in terms of levelling unless it was a windy day flying! but again towards the end they were up and down in thrust, could be interference if you were not moving the sticks up and down.

crazy vibrations too right at the end most likely from all the loss of signal

your att gain isn't on....1%

It makes sense that it's interference because you were at just about the furthest point from yourself when it happened, and you were near a house that could have a strong wifi signal maybe??? What is your radio set to do on failsafe? It looks like you were holding full pitch and when it lost signal it went to 0, (so did throttle) then it came back when you were still holding full, and 0 again until you hit the failsafe, but by that time it was too late to recover as the copter was plummeting out of control.

URBAN Myth! WiFi will not interfere with any present day frequencies used by RC equipment.

no but a dude with a killer ham radio can create enough noise floor to make range not as far as it should be,,,, lots of stuff can, repeaters, goverment coms.... etc.

I set my gain 1.3, altitude hold 1.2.
I was happend on same spot 2 times, my hexa out of control. Usualy I set full throtle and stabilize hexa from stick or switch to rth. but this time it wont help. Mybe I flew too fast or heavy wind interference.
On my hexa, motor and propeler are perfect balance. I put 5 pilar support in center frame to add rigidity on my hexa

Now, hexa are ready to fly again. I tried to take off but it flip. So mybe something I forgot. I did calibration, software reset. Mybe I shoud calibrate ESC again.
hopefully nothing broken on my FC

Good to have a blck box this is a first time for me to know exactly what happen instead of wandering and thanks to Multi rotor forum member for helping. Its interesting subject to discus

WIFI? Thats another possibility. I think there is 1 or two restaurant near the area, they probably provide a free wifi and it was full pack of guess at weekend. Assume that many people using smart phone/wifi can interfere signal/Hexa FC?

Sure looks like a bad radio to me. Any external interference from an outside source would probably be present to varing degrees throughout the entire flight. This isn't. Everything was fine for a while then, bango bogus radio command city. Old Dave's right though, the battery dumping out like that could have disabled the radio, too.

You are not reading correctly WiFi will NOT affect radio frequencies used with your radio

Thanks David,
From now we dont have to worry to wifi signals interfere our quad FC/TX
Would you explain more
I will feel more confort if I can understand technicaly

Sure! go here to understand why frequencies don't overlap unless illegally modified and even then lack the power for distance, a reason we all don't wind up with brain tumours from smart phones.
