Thanks Acdii and cmy6.
The wing was sheeted and then glassed before applying Klass Kote epoxy paint. The aft section of the fuselage was covered with Solartex then painted. The forward section of the fuse was also sheeted and glassed. The many thousands of rivet heads were hand punched using aluminum soda cans and lithoplate that a good friend supplied me with. Each rivet was attached to its surface using the tip of a soldering iron.

Some day I will get around to making my booth that vents outside so I can spray KK. Been using latex automotive paints for my warbirds, but have to shoot the clear outside, which means only in the summer, so it never gets done.

Is that a Sig Fazer in the upper-right background? One of my favorites.

My Feedback: (3)
Hello guys.
I'm building a Sig 1/4 scale Piper J3 Cub, I'm getting ready to start on the wing. I have a few questions on modernizing the wing for transporting. I know the wing comes apart for transporting as per the plans, but was wanting to make it a 3 piece where the wing panels plugs into the center suction. Has anyone here done that? I just kinda need to know where to start. I've been building RC planes since the early 70s, but have never build a 1/4 scale Cub, they've all been 1/5 scale float planes, so I'm not a newbie kit builder, just looking for a little advice to keep me out of making a mistake. I know I can figure it out on my own, but thought to check here and see what idea's I can get before I start. Not sure what size aluminum pipe to use, was thinking maybe 1/2 toward at the main spar and 3/8s aft. I also wanna get the dihedral right.
Any help would be greatly appreciated!

I would build it per plan up to where you want the section to end, then take that rib and make two out of plywood, use a tube and sleeve that fits that rib and a dowel pin at the rear to align them, and finish building the wing per plan so the length remains the same. Do the same for the other wing, then instead of following plan for the center where the wings would normally join, make a spar section that joins the two panels at least two ribs out on both and epoxy the center together. As for joining the outer panels, you will need to come up with that on your own since I don't have plans that show the wing. What I have done in the past is to use a 3/16 - 1/4" plywood plate that is epoxied on either the wing panel, or center section that slides into the wing and secure it with a T-nut and bolt or two.
On my B-25 I have a setup like this, the aluminum tube is glued into the outer panel, the plywood plate is under it on the outer panel, and the T-nuts are in a plate above the tube so the bolts go in from the bottom, through hardwood blocks under the tube in the CS, through the tube and into the T-nuts. Secures the wing tightly and only shows the small holes underneath where the bolts go in, the heads flush with the surface.
