Ah, poor Ramy RC and his 787. I've watched this before and see his evaluation of what happened.
Best I can figure is a servo failed or, maybe even a brownout. Either way, with how much work he puts into his airplanes, its sad to see it crash so hard.

What a shame. But it looks like a classic stall to me too. And if this was a maiden flight then perhaps it would have been a good idea to first practice stall recoveries at a safe altitude.

Ouch! What a tragic loss after so many months of building it.

I saw this too.. much's the pity
REmy is a class RC guy
I do believe the firs assessment at the site is the correct one... too much angle on those wings negates Lift... and then the spiral of death....

Ramy said it was a stall. Not enough speed in the turn.

Wonder if there have been some prior experiences of RF issues due to those nearby hi-voltage lines? Check the esc logging...did she go into failsafe? I see control surfaces still moving at the end, but perhaps those are just the gyros responding. Did the motors cut-out for a sec before gunning-it with the draggy flaps? I'll admit the timing is curious...

1994 Fairchild Air Force Base B-52 crash - Pilot Error Airshow (2 min 26 sec)

Looks exactly like this famous b-52 crash.

https://en.wikipedia.org/wiki/1994_F...the%20aircraft.

Conclusions
The accident investigation concluded that the crash was primarily attributable to Holland's personality and behavior, USAF leaders' inadequate reactions to the previous incidents involving Holland, and the sequence of events and aircrew response during the final flight of the aircraft. Holland's disregard for procedures governing the safe operation of the B-52 aircraft that he commanded and the absence of firm and consistent corrective action by his superior officers allowed Holland to believe that he could conduct his flight in an unsafe manner, culminating with the slow, steeply banked, 360° turn around the control tower.[2]

The other environmental factors involved, including the addition of a new maneuver (the 360° turn around the tower), inadequate pre-flight involvement of Wolff, and the distractions from the base shooting four days prior, combined with Holland's unsafe and risk-taking piloting behavior to produce conditions favorable for the crash to occur. The final factor, according to the USAF investigation report, was the 10-knot (19 km/h) wind and its effect on the maneuvers required to achieve the intended flightpath in relation to the ground.[2]

Basically it is clearly pilot error. Too steep/slow turn. It's an airliner not a 3d plane.

It is joyless watching a really nice RC aircraft go in. But it is sickening to watch what happened to that B-52. RIP. Big jets are not meant to be hot dogged.

And yet there are thousands of safe flights with Spektrum (the correct spelling) radio equipment all the time. There is absolutely no proof that the crash was caused by a radio failure, thus, you, cmulder are speculating based on facts not in evidence.

Classic wing tip stall, turning too sharply!!!

Too low, too slow, nowhere to go!

Not only that, lack of power to get out of the wing tip stall!
It might take hundreds or even thousands of hours to build models of this caliber, but more importantly, it take thousands of hours to master flying them to avoid disasters like in the video above, which speaks for itself.

Like he said at the start to much expo meant pulling the stick back more which resulted in a tighter turn... Rammy knows this but an airplane can stall at any airspeed, in any pitch attitude and this cost him to lose his 787
