WH9 then lays on top of
WH8. Each of these pieces
should be epoxied in position
for maximum strength. Use
a small clamp to hold the
WH8-10 lamination in place
while the glue cures.
Step 75 - Fuselage Assembly (rear wing mounts - right)
Using the remaining WH8, WH9 and WH10 repeat this assembly
on the right side, making a mirror image of the left.
Step 76 - Fuselage Assembly (servo rails)
Using some of the leftover 3/16”
x 3/8”basswood strip, measure
and cut the front and rear servo
rails. These are pushed through
the rectangular cutouts on both
sides of the fuselage. Glue these
into place.
Step 77 - Fuselage Assembly (block sanding)
Before attaching the tail pieces, now would be a good time to
block sand the fuselage. Make sure each of the sides are smooth
and remove any extra wood from your cuts. A little extra work now
will pay off nicely after your Robinhood 25 is covered.
Now it’s time to start construction of the tail surfaces.
Prepare your work area
Position the horizontal stab /elevator plan side over the surface
and tape into position and cover with waxed paper.
Step 78 - Stab/Elevator (S1 & S2)
Locate the two S1’s from
BP1 and the four S2’s from
sheet BP2. Carefully stack
the two S1’s and glue them
together to form a single
1/4” thick S1. Take two of
the S2’s, stack and glue
them to form a single 1/4”
thick S2. Do the same with the remaining S2 pieces.
Step 79 - Stab/Elevator (stab trailing edge)
Measure and cut the
stab’s trailing edge from
a piece of 1/4” x 1/2”
strip. Pin this in position.
Step 80 - Stab/Elevator (S1 install)
Take the S1 assembly,
position and glue it in
place.
Step 81 - Stab/Elevator (S2 installs)
Take one of the S2 assemblies, position and glue it in place on the
left tip of the stab. Then do the same with the other S2 on the right
tip of the stab.
Step 82 - Stab/Elevator (leading edge)
Measure and cut the
stab’s leading edge
pieces from a piece of
1/4” square strip. Pin
these in position and
glue into place.
Step 83 - Stab/Elevator (stab ribs)
Measure and cut the stab’s internal ribs from a 1/4” square strip.
Take care to match the angles for a good fit. Pin these in position
and glue into place.
Step 84 - Stab/Elevator (elevator leading edges)
Once the glue has set,
remove the stab from the
plans, then measure and
cut both elevator leading
edge pieces from 1/4” x
1/2” strip. Be sure to cut
the notches on the inner
sections where the joiner
will attach. Pin these in position.
Step 85 - Stab/Elevator (joiner)
Measure and cut the
elevator joiner to length
from the included 1/4”
dowel. Glue this in
position.
Step 86 - Stab/Elevator (trailing edges)
Measure and cut the elevator’s trailing edge pieces from 1/4”
square strip. Pin these in position.
Step 87 - Stab/Elevator (inner edges)
Measure and cut the inner edge pieces for both elevators from 1/4”
x 1/2” strip and the trailing edge pieces from 1/4” squarestrip. Pin
these in position and glue into place.
Step 88 - Stab/Elevator (elevator tips and ribs)
Measure and cut the elevator’s tips and internal ribs from a 1/4”
square strip. Take care
to match the angles for
a good fit. Pin these in
position and glue into
place.
