What does this do? It's used in R/C Pattern planes This might be a good question from new member Chip Hyde.

Maybe for stability in hovering/very high angle slow speed type manuevers. Something only the Bi-slob type worries about doing. But it also looks too small to have slow speed effect.

It could also be like the famous "chrome eagle" at Indianapolis. It was said that if someone at Indy had a chrome eagle on their car and went fast, everyone would end up rushing back to their garage to install one.

Hi Larry

This is the first time i have ever seen this in a model. I would really like to know what its purpose is too.

Without seeing the whole ship I would guess that is Kenny Stevens' airplane. Maybe he'll jump in here if he is a member. I have discussed it at length with him at a couple of contests, but hesitate to venture the facts as he told me for fear of twisting it around. The old memory ain't what it used to be.

In case the main wing folds up in flight, you will have a back-up?

Don't know abut RC but it gives a CL guy one more thing to fix when it breaks off. I asked Kenny about it and I'm pretty sure he said he couldn't see a big improvement. His new one this year didn't have one.

I googled and found another shot of the same model, but it was taken early in the morning.

He doesn't want to tell you the secret really behind the little wing. Really it is there to make people ask questions about it so he can give each one a different answer. It does blow the mind, cause I don't beleive the R/C guys have an answer.

Howard Rush · « **Reply #11 on:** December 23, 2012, 01:26:48 PM »

Vortex generator. My guess is that it keeps the flow attached to the vertical stabilizer at high wing angles of attack.

Lynn Weedman · « **Reply #12 on:** December 23, 2012, 01:53:30 PM »

only a wind tunnel test will reveal the true effects that are created in relation to the control surfaces and the attitude and speed of the aircraft. The full size jet type aircraft that I address issues on everyday have these types of devices installed at different locations and have different various designs for the type of vortex effect needed.

proparc · « **Reply #13 on:** December 23, 2012, 01:58:08 PM »

I can't believe no one has figured out what its for by now. It's there very obviously, to make his ship look like a super cool 2M pattern ship.

Of course he is going to need split ailerons, split actuating rudders, iso engine mounts, hattori spring loaded pipe, or plettenberg gear drive, split front fuse, recessed landing gears under the pipe, naca 640-012 root and tip sections,about 1000sq. of wing area, a fuselage 12 to 14 inches high and about 78 inches long, forced air cooling to the drive system, dual drives to the elevators, push-pull on the rudders and multiple condition radio programming with laptop download,to make that canalizer REALLY work.

Chuck_Smith · « **Reply #15 on:** December 23, 2012, 03:24:25 PM »

If I was a bettin' man, I'd guess he wanted the vertical area for knife-edge manuevers, and the wing increases it's effective span regardess of which side is up.

If so, pretty ingenious.

My guess is the fact that you asked the question has revealed its true purpose, was probabably taken on April 1st

Chris Wilson · « **Reply #20 on:** December 23, 2012, 06:43:23 PM »

Apparently with the Kenny Stevens model it is to "assist in overhead maneuvers " by giving more lime tension in vertical eights, overhead eights and the hourglass.

SteveMoon · « **Reply #21 on:** December 23, 2012, 08:34:49 PM »

Chris is exactly right. That little wing is most effective at generating
extra line tension at the top of the hourglass. They are very common
on RC Pattern planes, and as mentioned before assist in knife edge
maneuvers by cleaning up the airflow over the vertical stabilizer and
making it more effective.

Later, Steve

Serge_Krauss · « **Reply #25 on:** December 24, 2012, 11:50:32 PM »

As Posted prviously, it's a device used by top RC Pattern flyers for better knife-edge performance. MA has covered its use.

Dan McEntee · « **Reply #26 on:** December 25, 2012, 12:08:38 AM »

I gotta ask the question then, how do our models know when they are in "knife edge?" A properly trimmed stunt model should already pull nearly the same all over the circle, and because it is tethered, it is always in an optimum attitude for knife edge flight no matter what it's position in the hemisphere. The vertical stab of a C/L stunt model is not used like the vertical stab and rudder on a pattern ship. The effects of drag and gravity are different on a c/l stunt model than on a R/C pattern ship trying to track a straight line parallel to the ground. And because of the constant flight attitude of the center line of a stunt model in the yaw axis, if this appendage does indeed help the flight of the airplane, it should be effective at all parts of the hemisphere, I would think.
I just wrapped the last present and put it under the tree and now I'm gonna lay my head down and wait for Santa to come. MErry Christmas to all my friends in Stunt Land, and may we all have a Happy and Healthy New Year!!!

I thought it had something to with vertical CG. Where's Kenny Stevens. He'll tell you. Woops. Kenny Stevens has spoken.

RC Storick · « **Reply #28 on:** December 25, 2012, 06:17:19 AM »

with the low speeds we fly at I would bet the airplane would perform the same as if it was there or wasn't there. So zip besides it being a gadget to make people ask questions and shade the imagenary pilots head. Sorry Kenny JMHO

It MIGHT do something on a RC plane MIGHT. But if it was of significant value why are they not on jet fighters?

The idea of the winglet is to stabilize the airflow around the rudder during the knife edge. This is "old school" solution, AKA 2011. 2012 models feature a retractable fin. Apparently the fixed winglet generates undesired vortexes in level flight maneuvers.

At least that's what I gather from MA rag. Yes, I read other sections beside CL Stunt and Engines.
