Next install the tailerons. Each taileron has a .157” diameter carbon spar
that pivots inside two small pieces of 3/16” diameter aluminum, which are
supported by two small squares of 1/64” ply glued to the foam inside the
inlets.
Begin by sanding the tailerons to shape. Sand the leading edges to a well-
rounded shape and the trailing edges to a tapered shape. Put a strip of
3M Satin tape on the leading edges to provide durability and smoothness.
Also put a few layers of Satin tape on the forward root of the tailerons to
increase strength.
Cut the carbon spars and aluminum tubes to length. Glue the aluminum
tubes into the plywood squares in the inlets using epoxy. Make sure to put
the carbon rods in the bearings while the epoxy cures to ensure everything
is aligned. Then glue the spars into the tailerons using epoxy.
After the glue is cured, slide the carbon rods through the aluminum
bearings and slide the end stops and control horns onto each rod (but
don’t glue them yet). I used spare servo horns for both the end stops and
taileron control horns (just snip off the arms and drill them out to slide onto
the carbon rod).
Install the servo and make a pushrod using 1/32” music wire (Z-bends are
recommended on each end). Set the length of the pushrod so that the
servo arm and taileron control arm are perfectly vertical. I simply used
tape to hold the servos in place, combined with the friction from a tight-
fitting hole in the foam.
Adjust as required until everything is aligned—the control arms are
vertical, the tailerons are level, and the end stops fit snugly against the
inlet sides. Then put a few drops of CA on the end stops and taileron
control horns to secure them in place.
