jmdunstan, congrats looks fantastic,could you tell me how you did the graphics on the cowl? Did you only have to stick them on after having them cut?
Regards tmac.

chris. I have really started to get the gremlins on this site now, most of the time I get shut down because of a possible virus threat stopping me from logging in. Regarding the dash I really did not expect it to fit my Model because I realised that it was not specific to the Barth kit. All is well looks good enough to me.

Hi Tmac

A little off subject, but when you applied the perimeter tape to your wings, did you have to cut it to avoid wrinkles when it was applied around the curved surfaces like the wing tips and the elevator ends or did it shrink nicely. I'm using the tapes from Scale Ribstitch out of Solartex.

Also do the wing root fairings overlap the balsa of the wing roots? This would mean that you had to cut the wings to slot into the wing root. Please put some pictures on the site to show me how you did this.

Regards to all

Errol, I suggest you do a test with the perimeter tapes on a curved area to get proficient at it, (I wish I had) I found that if I concentrated on securing the tape all the way round the tip in the centre only, then with the iron at a pretty high temp you work on the outer edges sort of shrinking and sticking down as you go. When I first started I got horrible results but I did get better at it in the end.
Regarding the wing to wing fillet, yes I know your dilemma hear also. I just kept sanding back the trailing edge of the wing until I could get the wing to slide all the way home.
As far as the tapes are concerned maybe some one else with more experience might jump in and enlighten the both of us.
Do get back on how you get on.
Regards tmac.

tmac48:

The "teardrops" on the cowl were individually stuck on. It took a little doing, but the thin vinyl supplied bu Cal-Grafx is so pliable that I was able to burnish it onto the compound curves of the cowl blisters. Once thoroughly dry they were sealed on by the clear coat. You have probably guessed that I did not use the decals that were included in the kit because they are yellow (called "cream"), and I wanted white graphics.

To apply perimiter tape I firmly seal down the trailing edge at the last inch at the center of the tape. I then sit in a chair and with the wing held vertically between my knees, wing root at the floor, and pull like hell while ironing down the center of the tape along the tip frame.
You'll see the tape trying to conform to the upper and lower surfaces of the tip. Once you're at the leading edge all that's required is to iron down top and bottom with extra heat sometimes from a heat gun being careful not to shrink the tape width wise. Practise with some scrap material on a similar structure so as not to ruin that expensive pinked stuff. Mitch

Hi Guys

Do you ever feel like you are going nowhere with your plane, because that's the way I feel lately. I think that I have taken too long with this project. I've been covering, painting parts, making light covers, work, work. Dozens of parts are ready to be put together. Here are some pictures.

Hi Tmac

This is where I got my cockpit from. They make 1/4 and 1/3 scale.

Errol, have you any photos showing the dash in-place ,also what is that bracket in the third photo? post more photos of your build please.

Don't burn out on this project Errol. You're 90% done.......only 90% to go. Wacos are a diabolical test of patience designed by the devil himself. Mitch

ceije

Errol, I have to agree with you I'm in the same boat, I feel like i'm getting nowhere fast. Great fotos, your much further along then I. Your landing light shades are a work of art. I think Mitch hit th nail on the head. It is a test of patience designed to break the best of builders. It seem that the more you do the more there is to do.
I'm still futzing around wiith the wings, I lost the lower ones when my engine fell off the bench and destroyed them-MURPHY STRIKES AGAIN-there rebuilt now to put the guts back in. Your bird is coming along and looking great, KEEP THE FAITH.

Hi Tmac

I do not have any photos of the dash in place, but I have made a backing panel on which to mount the panel. What I can do is mount it temporarily to give you an idea of what it will look like.

The bracket is actually a counter weight that is attached to the bottom ailerons, supposedly to stop flutter. There is actually a name for these devices, but I don't know the name.
Stickbuilder you will know.

Chris, you once asked me about the weights

Mitch

Thanks for the kind words of support. The problem is as you progress, you tend to want to add more and more detail, and you become more and more critical of yourself to the point that you sometimes ask yourself whether you are building a plane or a Swiss watch. My late father once told me that you must do things properly or not do them at all, and that's my philosophy.

Thanks guys for all your support

Thanks Errol, I had forgot about those counter balance's (static) I went the 4 servo rout thus did not use them.
Chris not sure if I was able to get the PM to work if not then in answer yes top of bottom wing.

Stickbuilder

Yep, they are called counter balances. Can't even think of a better term for them. They are supposed to equalize the weight of the control surface at the hinge line.

Jim, what info did you supply cal-grafx to get your graphics cut?

My Feedback: (1)

They ARE counter balances but in aircraft lingo they're called static balances which differentiates them from aerodynamic balances (usually some surfaces area forward of the driven surface). My Waco has counter balances built into the ailerons which allows them to be weightless in relation to the hinge line when in a neutral static position. In my mind it was a good thing to do since only the bottom ailerons are servo driven on my project. Mitch

tmac:

I sent one of the decal sheets from the kit to them. When I ordered my graphics I told Cal-Grafx there would probably be strong demand for graphics for this model. When I received my graphics, I sent them a message advising that I would advertise their product on this forum. I expect that if you e-mail them and ask about a set of decals for the PICA 1/5 scale WACO YMF-3, they will be able to quote a price from the files they created for mine.

Good luck,

Jim

I was going to go for the four servo route, but hiding the servo wires to the top wing successfully presented a bit of a problem. So, two servos and counter weights is the route I chose.
The plane was designed that way by Peter Barth.

Thanks guys for all your input.

Regards

ceije

Errol, yes we did talk about the counter weights a while back but I went to the four servo system. I found that the paino hinges even with a lot of work still tend to be a little stiff for just two servos. Yes, there are those that will say it is over kill for a 1/4 scale bird. Building is always a learning platform...

Tmac, thanks..

Don't know if you've permanently installed your piano hinges yet Cejie. If not you could try what I did. I pulled the hinge wire and replaced it with a slightly narrower guage wire. The slop is negligible but the free swing of the hinge is now perfect. Mitch

ceije

Mitch, Dan had suggested the same proceedure and had shown me his. I did try this but the wire would only budge about 1 1/2 in. Before it would break off, I don't see any reason to cut up the rest of the hinge. I did soak the hinge in W-D 40 and with a little back and forth flexing it is very close to the results of changing the wire.

Chris what material is your piano hinge made out of? I was able to get some aluminium hinge and have not had any binding issues at all.

Errol Levin

Hi Ceije

I'm confused. Did you not get Kavan pinned hinges for your ailerons with your kit. Why are you using piano hinges?
