Default Help building struts

I know someone can help with this, but I've never done this before. I recently acquired this bipe, but don't even know the name or manufacturer. It's rather large, with a Super Tigre 3000 in it. My problem is, it came without the outer wing struts. The inner struts are 4mm in diameter. And I know the struts should have the "N" shape to them for proper rigidity and strength, but does one measure and figure out the lengths? Also, I assume soldering the components together is required. Any suggestions would be helpful.
Thanks,
Mark

Yes Sir , Struts (properly called "cabanes") will make the wings alot stronger , with regards to resisting flex in maneuvers . On all of my Biplanes , the cabanes are made of either model aircraft grade plywood , or somewhat flattened aluminium tubing . The cabanes are usually located at the 3rd or 4th rib in from the wingtip , and attach to the strongest structural members in their vacinity . In practice , Ive usually seen things like "doubled" ribs and stringers in the areas of the wing where the Cabanes attach . If it were mine to do , I'd set up the proper attachment points (areas) on the wings first , and then go about measuring the distance between these attachments for cabane length . Depending on your choice of cabane material , even simple "Eye bolts" of the right size could work , and then its just a simple matter of attaching the cabanes between the two .......


Course , , another option , , would be to make an approximate copy of the cabane structure on a similar sized biplane ......

Best of Luck , and Happy Flying ....... [8D]

PS , Nice looking plane ya got there !!!!

OOPS , , looking closer , I now see that the attachment points are already built into the wings ..... GREAT !!!! , , , thats a HUGE load of work already done for ya , , ,


Now all ya gotta do is decide what you want to make them out of , , measure between the already attached mounting perches , and your good to go and fabricate some ......

Can you show a close-up of the attachment points?
