I own a couple of Beaver RX 550s and the wings are constructed with drag wires. Many other owners have upgraded their wings from the drag wires to aluminum tubes and since I have the fabric off one of the planes anyway, I figured I'd do the same.
The picture isn't of my wing but one that is constructed the same way. My plan is to install "u" brackets beside the current brackets holding the tubes that run front to back (compression tubes...?) and put in a similarly sized tube on the diagonal indicated by the red line.
My questions are as follows:
- does it matter which way diagonally I put the tubes?
- what type and size tubing should I use? (currently planning on 6061-T6 with either .035" or .049" walls)
- how should I attached the "u" brackets to the spars? (3-4 Cherry Q rivets or 1-2 AN4 bolts)
I plan on attaching the tubing to the brackets with a single AN4 bolt although I guess a few Cherry Q rivets would work there too...
What do you guys think?
