pushrod housing should be glued into position in the holes in the
firewall and former.

9) Now install the motor as described in step #4 of this section.
❑
10) Now install the fuel tank as described in steps #1 & #2 of
this section.
TAIL SURFACE INSTALLATION:
For the following step you will need:
The Fuselage
• 1 each Horizontal Stabilizer & Elevator Set.
• 1 each Vertical Fin & Rudder Set
• 1 each Formed Elevator Joiner Wire
• 1 each Formed Tailwheel Wire
• 1 each M2 x 20mm Phillips Head Screw
• 2 each M2 Flat Metal Washers
• 1 each M2 Hex Nut
• 1 each 2mm I. D. Wheel Collar with set screw
• 1 each Allen "L" Wrench; for 2mm wheel collar
• 10 each CA Hinges; elevator (6), rudder (4)
❑
1) Prepare the fuselage to receive the horizontal stabilizer and
vertical fin. At the front of the stab platform, underneath the
covering material, are 2 balsa tail fairing blocks. The tail fairing
blocks are supported (to prevent shipping damage) by extra
spacer blocks, also underneath the covering. These spacer blocks
must be removed to allow installation of the stabilizer and fin.
a) Mark the positions of
the stab and fin on the
fuselage. Both the stab and
fin are 3/8” thick, so make
the marks 3/8” wide.
b) Remove the covering
material between the marks
to reveal the spacer blocks
that must be removed.
c) Cut the spacer
blocks loose with a #11
knife.
Slide the spacer
blocks out, leaving the two
covered tail fairing blocks
attached to the fuselage.
d) The remaining tail
fairing blocks should be
handled carefully until the
stabilizer and fin are
permanently glued in place
in later steps.
❑
2) Prepare to install the elevator joiner wire into the inboard
leading edges of both elevator halves. Start by first removing a
strip of covering material over the channel and hole that are
already in the leading edges of the elevators for the joiner wire.
Trial fit the joiner wire. Make any small alertations for proper fit.
❑
3) Use a toothpick or small dowel to apply epoxy into the
elevator joiner holes and channels in each elevator half. Press the
wire elevator joiner into each elevator half and lay the assembly on
a flat work surface, protected with waxed paper. Wipe off any
excess glue with a paper towel and alcohol. Make sure the leading
edge of the entire elevator assembly is straight, so that it will mate
up properly against the back of the stabilizer. Allow the epoxy to
cure completely before continuing.
❑
4) Use a felt tip pen and a small square to mark the centerline
on the top of the stabilizer.
❑
5) Test fit the horizontal stabilizer in place into the rear of the
fuselage. Position the stab accurately and make any final
adjustments that might be needed. We have found it helpful
to attach the wing panels to the fuselage before gluing the stab in
place. This provides a good visual aid when checking the stab for
level and also for being square to the wings in the top view. Slip
the stab in place, being careful to align it squarely and that the slot
at the rear of the stab is aligned with the fuselage sides. With the
fuselage on a flat surface, sight the model from the front. The stab
should be absolutely aligned with the wings, without leaning to one
side or the other. If it is leaning, use a small weight or a little
masking tape to straighten it out.
