Hinged Ribs

Posted on Updated on

Three ribs on each wing are reinforced for the aileron hinges. Two areas of the rib are filled with 1/4″ plywood RS-672. I removed the cams on the jig in those areas so I could assemble the ribs with plywood.

I cut six of each plywood piece.

Rib number five on each wing needs these plywood pieces and gussets added to both sides like the other ribs. I built both of those and now only have four ribs remaining.

The last four ribs are the root and tip ribs, each one is unique and requires some additional components.
