Painting

Finished polishing the wings and started painting them. Finished with the gray, and continued with orange. Started painting the trim on the fuselage also,

Wing tips, lights and polishing

Painted both wing tips, and riveted together the light brackets. Finished two runs of F9 polishing compound on one wing.

painted one wing tip

Magnetometer

Made two small beam like brackets of 5mm aluminium, drilled holes and tapped them for m4 bolts. The bolts will be long enough to hold the magnetometer with 4 m4 nuts. All is stainless (non magnetic). Then RTVd them in place, so the bots can easily be replaced (maybe I will use some that are a bit more aerodynamic). The tips are finally ready for paint.

Nav lights

The brackets for the lights.

Wing tips, nav lights

Finished with the removable wing tips. Started to figure out how to install lights and the magnetometer. The wingtip lights are supposed to be visible from all around, and therefore needs to be mounted vertically. I think I just use some leftover cuts from the ailerons and see how it works.

Wing tips

Tried different ways to get the tip on straight. To position the wing upright, strapping the tip on and using a ruler to adjust, seemed to work OK. The straps with the nuts is to be inside the tip. They are drilled without the tips in place, and they need to be trimmed a bit to make the most fwd hole to fit due to the curvature.
