Downwind turn Myth

A cub moving slowly into the wind is flying on the wind, not on actual airspeed. Change the direction of flight away from the wind and that's when you find out if there's enough wind moving under the wings to provide lift. If there's not, it falls. I have to laugh at how very simple this is, and apparently how difficult it is for so many here to understand. If you're all smarter than you appear to be here and you actually DO understand how it works, then you're all just arguing phrasing and semantics. That's futile, and it involves egos, not knowledge.
Here's a suggestion. Reduce your wing loading. Use a bigger motor/engine, or push the throttle stick forward more. Problem solved.

I started this thread 5 years ago, and I now officially give up. The downwind turn myth is real. The airplane doesn't like being turned downwind. Turning downwind is bad, makes wings lose lift. Why I never noticed this in my aerobatic or airline flying over the last 40 years is the real mystery here.
While I'm cleansing my soul: Sasquatch and the Loch Ness monster are real too. Elvis is still alive. There are little green men in a morgue at Area 51, and I am sure that Anastasia survived in spite of DNA evidence to the contrary.

The biggest problem which I've found leads to problems such as belief in these and similar myths is that RC people have no clue about how an airplane actually flys and what actually happens in the air. They don't even realize this.
These guys later become "instructors". They have no clue about that either and have no idea how to teach.
Then they act as authorities and perpetuate these myths with the students. And on it goes.
Speaking as a pilot and former aircraft owner, I'd suggest that these myth believing experts and hypothesizers get into a real full sized small aircraft and have the pilot fly into the headwind and turn to downwind, while maintaining constant airspeed at about 500 ft. to 1,000 ft. AGL The observer need simply watch the ground the entire time. Then, just maybe, the difference between airspeed and groundspeed, which is causing the confusion, will become obvious.

Airspeed is airspeed irrelevant of groundspeed.
But... Like Frank Zappa said: " people will only agree with you if they already agree with you, you dont change peoples minds"

This thread is beyond moderation.
Elvis is back in the building following a masterclass in down wind turns from our beloved leader Kim during his alien abduction when he crashed due to wind gradient while circling a hot air balloon..
Post one thousand three hundred and eight six and counting.

I have had the downwind to upwind turn get me at least three times back when I was just learning to fly models. They all occurred when I was dead stick in moderate wind and made the mistake of trying to turn from a downwind glide to make the runway. I soon learn that the plane would stall as soon as I turned to the upwind leg. Lesson to learn, if your are dead stick don't try it, just land straight a head into the wind. Unless you have allot of altitude you can use to recover your airspeed. It doesn't relate to ground speed, which ya don't know anyway, It has to do with having enough airspeed to keep the plane flying as you make to upwind turn.

Yeah if you what to be concerned with ground speed which can mislead you, that is where the error comes in. Letting the plane slow down too much is indeed the problem. As you are flying down wind in a glide you will if fact be carrying a greater ground speed than you would in a no wind condition glide. That is where the illusion can mislead you into thinking you going fast enough to make the upwind turn, that's when the stall happens. If you have engine you can power up most times and recover, but maybe not, it depends on how much wind there is, and your power available.

Semantics. Once you know what makes a plane fly in all conditions, all these arguments mean nothing, and no matter how many names are called and no matter how many arguments are used, it doesn't change a thing. You can make it happen on a flight simulator. It ain't rocket science, and common sense is all it takes to understand when it'll happen, and what it takes to keep it from happening. It's aircraft piloting 101, it's a basic situation any new pilot deals with.

When you are in a plane flying by instruments, upwind/downwind makes no difference. When you are on the ground trying to fly a rectangular ground track,
1) you'll crab into the wind on the crosswind leg
2) it will require more than a 90 degree turn to transition to the downwind leg
3) over banking to complete your crosswind to downwind turn can cause a stall.
Agreed?
If so, then the turn to downwind didn't aerodynamically cause the stall (over banking to maintain ground track did), but the turn to downwind needs to be respected more than the turn to upwind "IF" trying to maintain a ground track.

I must point out the biggest myth of all posted here that you guys totally ignored. Look Elvis is DEAD, dead, D --E--D DED!!. But a true fact about him that you may enjoy:
The hottie actress and dancer Rita Moreno (played Anita in West Side Story and is STILL HOT) used to date Marlon Brando. She had some reason to make him jealous, (don't know why, probably he was cheating on her) so she did it by dating Elvis. Now this is one hot woman, dating Elvis just to make Brando jealous. Anyways, she claims to this day that Elvis was lousy in bed.
TRUE FACT.

This is seriously the most amusing thread around. It's brilliant.
I love all the people out there quoting 'It's the truth' , 'It's fact'.... blah blah blah. Yet, they have absolutely no idea what they are talking about.
Here's a FACT.... just because you fly RC or a full sized aeroplane, doesn't mean you understand what you are on about.
Here's another FACT for all you people going on about Groundspeed being the issue. You can stall ANY aircraft with even a billion knots groundspeed. GS has zilch/nadda/zip to do with you stalling.
But seriously.... keep the awesome comments coming. Who needs TV
