Clean Linkage Install

I wanted to share this. I made a really clean linkage installation on my ailerons and flaps using a simple piece of 0.063" steel wire with an L bend instead of a clevis. This enters the wing through a narrow slot which is made forward of the rear spar and avoids notching it. The wire is retained by two 0.063 brass washers (from Microfasteners) soldered on either side of the horn.

On the servo arm end I use a second piece of wire with a Z bend. The two pieces of wire overlap by about 1" and are soldered together. You can easily adjust the length of the linkage by melting and resetting the joint.

This method gives a really stiff, tight and lightweight linkage, in addition to not requiring a big hole in the skin and a notch in the spar.
