Steve,
You have all the ribs to make as close to scale wing tips as possible. Here are a few pictures how I did them you may have to trim and sand a little on the last two ribs to fit the bow tips hope they help.

Thanks guys. I really didn't think that looked right, but now that I see this, I see it's not even ballpark. Straight to the trash with it.

They are in the Pica kit. As far as perfect scale, which is where this thread now resides, I don't think there is anything usable as "scale" in the kit.

What about the aileron corrogations? Are they worth using?

You should be asking yourself the question of how “scale”you want your airplane.
YOU need to decide how YOU want YOUR airplane to look. Then you can use the information in this thread to help you build the plane the way YOU want. If your question is asking others to decide how YOUR plane shouldlook, you may never come to a place of consensus or happiness about how your airplane looks.

For me, my airplane looks great, fly’s great, and makes me happy. I did not use the aileron overlays. My own reasons are that the vinyl overlays add weight and drag and don’t look good if you just glue them over the wood. There are simpler or better ways to achieve that effect.

In any case, no one at the field has ever come up to me andasked why I did not have corrugations on my ailerons, but I sure receive a lotof compliments on it. This is a great airplane whether you go sport or highdetail or anywhere in between.

Well that does make perfect sense. It will probably fall somewhere I between. This is my first time really adding a lot of detail, so I DO want it to look great, but I not going to loose sleep if a detail is off. In fact, I'm sure even after all is said and done, it will probably still be farther from scale than anything else. I'm only asking because I don't have the eye yet for scale that some of you have. Some things, to me, look right, but you see something totally different. Like the plastic coronations, they look right to me, but maybe there way off. If that's the case, I would make my own. But if there close, then I'll use them. I'm sorry if I'm asking too many questions, I just want it to look good.

If I had to go back and add corrugations, I would have simply glued balsa triangle or square strip lengths directly onto the bare ailerons and blended them into the aileron with light sanding. Coat the whole thing with finish epoxy, a light sanding of that epoxy and than primer and paint.
I am sure there are other different or more scale methods, but that would fit my laid back easy way of getting more scale.

Steve,
You can't ask to many questions so ask away. As far as the corrugations go they are one of the scale details that make the plane look fine I would definitely use them in some form.

Steve,

The full size ailerons are quite thin at the trailing edge being made from sheet aluminum, total thickness less than 1/16". The kit trailing edge is thicker and just balsa. Add the plastic corrugations just exaggerates the thickness. I would do what was suggested above, apply 34 triangular strips, either balsa or plastic, sand them to round off the top and give them a coat of finishing epoxy to make them smooth.

The balsa trailing edge could be sanded to a knife edge, allowing the top and bottom plastic overlays to come together, reducing the thickness to just twice that of the plastic sheet.

The ailerons are quite easy enough to make. Maybe I'll try one of each and see how they look. I'm going to re-do the cabanes again. I just don't like them, and I was a bit off with the heights. Hopefully the third times a charm.

waco1,

That is a possibility. There are a number of problems in doing so. You need to sand enough of that the dimension of the aileron is narrowed enough to maintain the correct dimension when the plastic sheeting is applied. Just applying the plastic so the edges meet would extend the width to much wider than scale. Thinning the aileron some, applying the strips and using the finishing resin is the simplest way to accomplish our goals. Otherwise a whole new aileron would need to be designed.

I'm going to try one like that later today and see how it looks.

Sky--Yes, the ailerons must be sanded to a knife edge for the plastic overlays to come together at the designed profile.

waco1,

True but 2 thickness of the plastic are too thick. The whole aileron has to be reduced the thickness of the plastic, not just the trailing edge, otherwise it will end up too thick at the leading edge and middle as well. Go ahead and build an aileron per the plans and sand it down until you get the plastic to fit, not going to happen. If one were to skin the aileron with 1/128" or 1/64" plywood and apply the plastic, it might work to get the narrow trailing edge. Even using sheet aluminum to make an aileron would still make the trailing edge too thick, the full size is only 2-3 thicknesses. Dave Platt's saying - You sometimes have to build it wrong to look right. It applies in this situation. Enough said about this subject.

Only if you want the last word.

The kit-supplied plastic was meant to be installed over the supplied balsa parts, scale or not. If you take the time to reduce the trailing edge's thickness to zero, you will have only the 2 thicknesses of plastic overlay. Should be fine.

You know, I tried that once. But I could never get the edge to zero thickness, everytime I got close the edge disappeared.

Robert, Didn't you build the adjustable stab on your WACO a couple years ago?

Well anyways, you all were right. I can't seem to get the ailerons to look right with the plastic corrogations. I did one the way someone was saying with the strips and finishing resin and it's coming out good. Time consuming, but then again, what isn't?im also working on the hatch and wing fairings. Lots of work.

Yes sir, I surely did!!! It worked great for getting the perfect flight angle. Then I epoxied it in place and pulled out the hardware.
Anybody wanna take a guess what that angle was???????

I'm going to guess that you left it a 2 deg....
Did the stab flex too much with the adjustable linkage?

Hello all
I will give the vote on the shirt color until Monday and give the final color choice then pass it over to Steve. Hopefully Bill will have the art work so Steve can get it to his printer. I'm lookin forward to getting some new shirts. Pm me with your choice of color if you haven't yet.

It was 2-1/4 for perfect flight with a neutral elevator. There was no flex or movement in the set-up.
