Slightly OT- Model B52 Crashes

It was the dreaded downwind turn. Too low, too slow. Google foe vids.


That's a real shame. Do they know what happened?

Since R/C flyers depend on visual cues, they do suffer from the downwind
turn syndrome, where the model's groundspeed looks OK, but the airspeed when
flying (or turning) downwind, isn't adequate. I've seen more than a few
crunched R/C aircraft because of this. Remember, it is a visual cue thing,
not an aerodynamic issue...

No not a joke. Have you ever flown an RC plane?????

Yes sir, I have many years and hours of experience flying RC's, I was an RC
instructor for our club also. If you look at the video it had already made the
downwind turn and flew quite a while before the crash.

My impression was that it 'stopped flying' before it looked like it stopped
flying. I think that's what dooms many a pilot because they continue to
pull after the aircraft as already stalled but before any sort of break.

Looked like the dreaded downwind turn to this old RCer

And yes, there is no such thing as a downwind turn except as an optical
illusion that effects the pilot.

It looked to me like it had already made the downwind turn and was turning
back into the wind when it crashed.

I went back and looked again. It did look like a stall out of turn to me.
It appeared to be perfectly oriented for the 'downwind' turn type of event.
I've seen many dozens of them (done a few myself). The clouds and the sock
suggest that et was a blustery, variable wind day which just makes it even
more challenging to fly. There appears to be a momentary bump where the
nose drops and the bank increases well before the turn completes 90
degrees - that looks like a stall. Did this thing have true to scale
spoilers for bank?

Having said that, there's no way to know for sure without telemetry. Flight
instruments is part of what makes full scale flight easier in so many ways.

Damn what a fine looking ship!

It looked to me like the pilot might have gotten confused which wing
was low and then corrected the wrong way. As the roll was continued,
the nose fell through. When an RC plane is flying and the light is
behind it, its often easy to get confused which wing has dipped to
know which way to correct. In that circumstance, you only know you've
got it wrong when it responds the opposite of what you thought it
should. A normal turn would have been back towards the camera to come
back over the runway, not away as he ended up doing and crashing.

For RC's, it is a real thing, only because of the skewed perspectives
involved. IMHO In other words, it looks like the model is going fast enough
to avoid stall, but a good portion of that perceived speed is because of the
downwind drift. Turn too sharp, low airspeed, high speed stall, = smoking
hole.
