Downwind turn Myth

HaHA I blame AOA. a little too much and you can stall inverted at the top of a loop. or on short final. Increased drag from a abrupt turn will slow and airplane even in a no wind situation. I will keep the down wind turn myth in mind for when I dumbthumb a plane in. Maybe if I call it the downwind turn phenomenon I can confuse enough people so I don't have to admit it was my weak skills. The best part is if I do this enough I will start to believe it as a truth. Then I won't have to take responsibility for my actions.

At some point I just have to laugh.
I am taking donations now (PayPal accepted) to NOT start a follow-on thread entitled "Torque Myth" wherein I attempt to explain that proppie motor torque is common catch-all misnomer and that torque causes a rolling moment only, whilst other factors are at play when your airplane yaws to the left....
Argh, never mind. I like RCU and don't want to melt their server down, so I'm gonna refrain from that one as a freebie :-)

Lots of interesting posts on this long thread for sure! How about this though: Would you rather fly with the wind at your back or with the wind in your face at the flying field?
If it's in your face and you slow up your plane on base leg for an apparent VISUAL speed, you might get it close to stall. Wind at your back is much more forgiving in flying a slow base leg. Anyone agree?

1300 + posts WOW. Even quoting Galileo. It gets better. Someone even bought in the veracity of Darwinian evolution.
No go for it. Go for it.
It will be in competition with the thread I will start on the physics of dynamic soaring or why unpowered gliders can go faster than powered jets.
For those unfamiliar with DSing watch this.

Ken may spank me for feeding the trolls.

I believe David Shulman (USA) who reached a speed of 293 Knots (542.64 km/h or 337.18 mph) holds the RC jet record.
The DS glider guys are close to 500 mph and may have cracked it by now.
Of course that speed may have been measured downwind.

Until folks can stop confusing themselves with ground vs. airspeed (like the post I quoted) I'm afraid that we will keep beating our heads against the wall. <kickscan>

Seems to me that we are comparing two completely different types of equipment which has completely different flight characteristics, that operate in different environments and flight conditions, to one another. Switch the environment around and each plane would not perform as designed.
Never the less, dynamic soaring is pretty cool. Guys were talking about this at the hobby shop that I frequent. But I get a bigger kick out of watching birds do this by instinct.

Sure you did. "taking off downwind" is meaningless unless you are talking about a mass of air moving relative to the ground you are taking off from. Go up in a hot air balloon on a day with a strong but steady wind, and launch your glider from that. Any direction will do.
Try this. Make a paper airplane. Hold it backwards into the windstream of a fan and release. See how well it flies.

Your paper airplane example shows that you need air moving over the wings (from front to back) to fly. Nobody disputes that. It has nothing to do with the forces acting on a plane that's flying.
