Stick Wing Reinforcement

Reinforcing the Slow Stick Wing
First glue the fibreglass rods into the aluminium dihedral
tubes with thick CA or Epoxy. Then tape the rods in position
on the front of the wing using 3 small pieces of tape on
each side making sure the rod fits tight against the wing LE
in the moulded in grooves provided. Then using thick CA or
epoxy glue the rods to the wing by running a bead of glue
between the rods and the wing. Then using 2"- 3M clear or
for more strength Extreme Packing tape wrap the rods you
have just glued with 1" of the tape on the bottom of the
wing and the other 1" of tape on the top of the wing full
length of the rods on each side of the wing. Repeat for the
back (TE) of the wing. If more strength is desired as in
using brushless power I then bend a brass dihedral tube to
match the front bend and glue 0.098 or bigger carbon rods in
the tubes so they stretch from wing tip to wing tip. This
assembly is then placed on the underside of the wing at the
CG point 4-1/8" back of the LE of the wing. The rod assembly
is pushed through a hole in the center rib and is glued
tight against the underside of the wing and covered with the
3M Extreme packing tape. Another carbon rod is then inserted
into the fold in the center rib pushed under the reinforcing
rod you just installed so it goes from LE to TE in the rib.
This is to prevent the center rib from collapsing. After the
reinforcing the center rib is filled with epoxy (see Note:
below). You now have a bullet proof wing!
I also glue flat carbon rods to the back of the fin and
stabilizer before taping on the elevator and rudder.
Note: If you have the new wing with the plastic center rib
insert install the insert first and then drill through for
the carbon rod/ dihedral tube assembly. Filling the center
with epoxy and the carbon center rib reinforcing is not
needed with the plastic insert.
