Title: What's "hinging?"
Post by: steven yampolsky on September 28, 2007, 02:53:46 PM

I'm confused. What's "hinging"? Is that a rolling action a model experiences in a hard corner? Is that a yaw or tail "wiggle" in the corner?

Your plane doesn't hinge Steve....

Steve,

Double the tip weight in your plane and witness.  :)

It is the action of both yaw and roll in combination when given hard control such as in a square corner. You see it most in a hard turn from level flight into a square maneuver.

The outboard wing drops when you pull out of wingover after doubling the tip weight as Randy suggested.
It is kinda confusing ,isn,t it.
Lots of terms today are very confusing.
1. 3D Airplane ??? wuzatt ?
2. Vintage sound ?
3. metal crunch sound?
4. Great distortion tone ?
 The list goes on & on VD~

This reminds me...Randy, did you take out that extra 1/4 oz of tipweight last Saturday night, when you took the .46VF out and reinstalled the .40VF?  H^^ Steve

Yes Uncle Steve. I did. If I could have gotten all the solder flux out of the tank, I could have a complete run, too.

Hinging looks a lot like stalling, just to keep things from seeming too easy and straightforward.   VD~   n~
Any of y'all aereodynamikul exspurt type of guyz out there care to 'splain the difference and confuse us compleatlie?

I am no expert, but, it is when the out board wing does not want to follow the same path as the fuse and in board wing.  Inside squares the out outboard tip wants to keep going straight while the plane is turning the corner and just the opposite on out side squares.  Now I am confused,  DOC Holliday

So far you haven't been given a clear and simple answer to your question. Hinging is the rolling motion about the aircraft fore and aft fuselage center line that appears to the pilot as the outboard wing flapping up or down on hard corners. Hard inside corners causes the outboard tip to drop and hard outside corners cause the OB wingtip to drop (which is UP when referenced from the cockpit). After the corner or in round loops the hinging is momentary as the tip weight "lags" behind the rest of the wing. Once a uniform rotation is established in a loop the tip returns to normal. The magnitude of the "hinging is a function of tip weight and OB flap size. So a heavier tip weight will present a greater "hinging" or outboard wing flapping than a lighter tip weight. This hinging does provide some vector the lift slightly away from the pilot and improves line tension.
