Glue in the servo mount for the tail
gear steering right behind the wing
saddle and reinforce with some
fiberglass cloth. Install the servo and
set up the pull pull cables. We
recommend to feed them through two
sleeves (white plastic tube) in the tail
wheel former (see photo). When the
tail gear retracts these cables lengthen.
Make sure that they cannot loop
around the servo arm and lock up the
tail wheel so that it isn't able to lock
down. We recommend to use a short
piece of Tygon tubing to make the
cables stiff in the servo arm area. You
can also use springs or rubber bands
and pull them sideways to keep them
under tension. But be careful that the
rubber bands are not too strong. This
resistance can also cause the tailgear
to not lock down properly. If you want
to use a Y-lead for your tailwheel and
rudder servo, you must cross over the
tailwheel cables to get the same
direction of deflection as the rudder.
Rudder Fin:
Take the vertical fin and slot its root
surface according to the plywood spar
penetrating the fuselage's fin fillet.
Slide the horizontal stab panels on to
confirm the correct angle and glue the
fin on to the fuselage. Sand the
surfaces with rough sand paper and
clean with alcohol before you glue
with 30 min epoxy. As soon as the
glue has set, mark the position of the
top hinge post by installing the rudder
temporarily. You can slide in the hinge
pin from the bottom side, but make
sure that you can grip it with a pair of
pliers later to get it out again. Mill the
top surface of the fin to accept the top
hinge post. There is only one hinge
post installed to the rudder, so make
sure that this post is mounted
properly. Glue in the plywood rib so
that the top surface of the 3mm
phenolic hinge post is flush with the
