I haven't made much progress lately as I got sidelined building a BTE Flyin' King. It's almost done, so I should be back on the PA-14 next week some time.

I did get an opportunity to get some detailed photos of how the Cub wings are attached. Hard to believe there only two bolts holding each wing to the plane, plus the four bolts holding the struts! Two guys can easily carry the wings around, and the flaps only weigh about 3 or 4 pounds each.

Those pictures remind me of the days I spent recovering many of those planes, yes they don't have many bolts in them but that way has been around for a long time and proved it's self worthy. Heck the early cubs only weighed around 1,100 lbs, up your way the still smash them up and go look for another, that's if they survive.

They build new ones up here too! You can see fuselage jigs parked outside at a number of shops in the area. Many of the cool mods came from here too. If you want to see a lot of Cubs, type in Lake Hood Airport into Google Maps!

Well, I finished the Flyin' King, and am back on the PA-14 build. I spent some time playing with the shapes for the aileron/flap leading edges and how they fit up with the wing trailing edge. Now I need to get the hinge scheme figured out.

Jeff if your doing them scale that will be a challenge because you can't do them with Robart hinge points. I have all the brass square tubing and flat stock to build my hinges so they will be like the real ones. I think I have it figured out and the clevis ends which look like yokes will be here next week, I even have the 1/4 scale turnbuckles coming. It will be fun making these things and I'm not going to make the flaps and ailerons until the hardware is done..

I don't recall the PA-14 having flaps, are you doing them, they would look good on it and be functional too.

Sorry Jeff forgot to mention your Flyin King looks good , nice job on the skis and I have never seen the cable ends you are using, where did you find them.

I'm working on a few mockups for the ailerons/flaps, and might have a solution.

Thanks Leroy! the Flyin' King should be fun training for the 1/4 scale Cub. It's an 80 1/2" wing, and weighs 9 pounds with the skis.

All the info I've found shows slotted flaps on all the PA-014s, and I helped take them off of my friend's plane. In fact, there's a picture up above showing them sitting on a cart with the ailerons. I will be building them for this plane also.

I'm not sure which cable ends you're asking about. If it's the ones on the skis, they are standard control line stuff with copper crimps. The string is Tufstrand, which I believe is Kevlar.

I sorted out the ribs after weighing them, that way I can be sure to have both wings weigh the same.

I built a little mock-up of the aileron/flap layout, and have an idea now of how to make it work. The Robart hinge won't give the scale effect I'm after. Square tubing, sheet aluminum, and Du-Bro ball links should do the trick nicely.

Jeff I think we are both on the same track where the hinges are concerned. Second picture on post #29 shows some bullet looking cable end covers or part of the attachment, I have never seen them before.

Holidays are putting a crimp in my building, won't get much done till after Christmas, hope everyone has a good one.

Hi Leroy,

What you're seeing there is a Great Planes deluxe pull/pull setup. It's about $10 at the LHS. Seems to work pretty well too!

Merry Christmas!

I picked this build up again after 14 months or so. I've had a bit of a re-think on power for this plane. I tested the Super Tigre S90K in diesel form on a Senior Telemaster, and while it went quite well, I don't think it's enough oomph for this plane, what with the scale gear 8" balloon tires, flaps, etc. I found a new G3250 and a diesel head for it, but then realized it would be way too long to fit in the cowl. I grabbed a 2300, and that seems to be a much better fit.

Both wings are now framed up, next will be installing the tip assemblies, with the laminated tips.

I can't believe the time has gotten away from me, or maybe I can. I'm back on this project at last. The fuselage is all done, just finishing up the windshield installation. Next up is finalizing the aileron and lfap hinging and final shaping. Pictures to follow...

The windshield turned out to be the trickiest bit of the whole build, but it'll have to do. The fuselage is now completely done. Now I just need to finish up the wings and build the struts.

I agree. The hardest part to any cub or cub-like build is the windscreen. Looks good!
