I build my own wing servo mounts/cover to hide the servo in the wing. My
pet peeve is a servo hanging out in the breeze! I started with two blocks glued
to the cover and had issues with the blocks breaking off. I then added triangles
to the blocks but it was a fussy job and still not as secure as I wanted.
The basis for the mount is a plywood rectangle cut out in the center for
your servo of choice. I use a downward-cutting spiral bit in my drill press set
to its highest speed and guide the bit by hand. Take your time here. You can
always clean up the edges with a file or small sanding block.
The top (cover) side of the mount can be sanded to match the curve of the
wing so the cover gives a perfect fit. Two small triangles of plywood stabilize
the servo mount on the cover. So far, I’ve not broken one, even in a crash!
The mount/cover in my photo is to mount a servo in a fairly thin wing so the
mount is fairly compact.
Keeping CA Tips Clean
I place my dispensing tips for CA glue
in a jar with acetone in it—enough to
cover the tips. I also put my spray can
tips in as well. The acetone dissolves the
CA and/or paint and makes them usable
the next time I need them.
Because acetone evaporates easily,
even with a seemingly tight lid, I put
some plastic film on top of the jar (like
the plastic backing from covering) and
this helps seal the jar even better.
When installing pinned hinges on
control surfaces, sometimes the glue
gets in the hinges and causes them to
bind. Before installing the hinges, simply
put a small amount of light oil right on
the hinge line. Be sure not to let the oil
spread to the part of the hinge you are
going to glue. This will ensure that the
hinge will not bind after the glue dries.
