Wing joiners

[ourblue]

I'm planning to build a 3 meter aileron/flap glider. Planning for a 3 piece wing with center section and wing tips.  Its an all balsa ply model with a pod and boom fuselage. there is no dihedral angle where the outer panels join the center. I was hoping to use rectangular brass tube with 2 layers of 1/16" aluminium strip epoxied to ply to make up the thickness.
 I used this method in the Bird of Time but wondered if it would be strong enough for an aileron model.
 I know that Gliders  do a steel and brass wing joiner  but I only need about 16 inches.
          regards

if you want a cheap joiner go to B&Q. Aluminium tube & steel rod to fit. Or you could use the tube to make a carbom rod joiner by drawing wetted out carbon tow thru it.

I'm sure Fred will have other alternatives too.

Hi Bill,
    Thanks for your help. I got the aluminium strip for the BOT from B&Q and they fit into a ply box at the join of the sections. Just wasnt sure if this method would be strong enough for an aileron model. I should have mentioned it will be electric so it wont have to endure a winch or bungee launch.
