BEFORE YOU BEGIN
A word about laser cut parts and adhesives.
There are three primary types of adhesives recommended for constructing your model. They are Cyanoacrylate
(CA) in all viscosities, Aliphatic Resin Glue (carpenters glue) and Epoxy. In the interest of speed, CA is the pri-
mary adhesive to use however there are times when it is not the best choice. They are:
1. When you need more time to carefully position a part than a fast setting adhesive will allow.
2. When attaching plastic such as a windshield (Use Pacer formula 560 here).
3. When gluing laser cut aircraft grade plywoods. The microwave set adhesives used in aircraft grade plywood
does not ablate well under a laser beam. As a result it burns the wood bers near by leav ing a charred edge. Fast
setting CA adhesives do not allow time for the adhesive to penetrate this layer of char and bond to the wood ber
underneath. Use a slower setting adhesive such as Aliphatic Resin or for maximum strength use Epoxy on aircraft
grade ply parts. Lite Ply’s do not use this type of adhesive and do not suer from this problem.
To apply thin CA I recommend the Dave Brown pipet’s available at your hobby shop. Be sure to stretch the end
(pull it with a pair of pliers) to a thin applicator tip, as they are not supplied in this conguration and some folks
don’t know that you have to do this. No mention of this is made on the package they come in.
I recommend revisiting all CA joints with an application of Aliphatic resin glue for maximum strength.
Assembling the registration pins.
We will be using two types of pins; registration
pins and push pins. Registration pins are assem-
bled from two 1/4” ply parts, one 1/16” ply part and
two 8d nails. Push pins will be used to temporarily
secure parts to the building board.
Locate the two 1/4” ply parts labeled PB and one
1/8” ply part labeled PB. Refer to the graphic at the
right and assemble using Epoxy or aliphatic resin
glue. After installing the nail, use Epoxy to secure
the nail from the bottom. Note that the assembly
must sit at on the bench when completed.

IMPORTANT:
The magnets used in this kit are the highest quality and strength available however you must take precau-
tions. DO NOT heat these magnets when covering your model. A temperature as low as 150° can deplete
half the magnetic strength.

Seamaster II Fuselage Assembly
Locate and prepare the two fuselage sides (FS).
Lay them on the workbench with the tops fac-
ing each other (back to back, see photo).

c 3
c 2Locate and prepare the wing saddle doublers
(WS).
Use the Registration Pins to install and glue it
to the fuselage sides. Note that you will make
a LEFT and a RIGHT fuselage side. See the
photo.
Locate the Fuselage Servo Tray (FST) and two
3/16” x 3/8” x 4” basswood rails. Note that
FST can be congured for standard size servos
(remove the dash cut area) or for micro servos.
Determine which you will be using and cong-
ure it appropriately. Glue the basswood rails to
the edge of the servo opening to provide mate-
rial for the servo screws. Glue them in position.
The left and right fuselage sides are laid out and the wing
saddles are installed using the registration pins.
Now is a good time to mark and drill the pilot
holes for the servo mounting screws.
c 6Install and glue the Fuselage Servo Tray assem-
bly to F5 and F6, note that the servo tray screw
rails should be on the bottom.
c 7Glue the F5 and F6 assembly to the RIGHT
fuselage side.
c 8Locate the Wing Mounting Plate and two #10-
32 blind nuts. Press the blind nuts rmly into
the holes provided in WMP.
Because WMP and F8 interlock it is best to
install them at the same time. First install and
glue WMP into the notches in F8 and then glue
this assembly to the fuselage side. Note that the
anges of the blind nuts should be facing down.
ABOVE: The servo tray can be congured to t standard or mini
servos. Remove the dash cut material for standard servos.
BELOW: F5, F6 and the servo tray assembly.
c 10 Test t the le fuselage side to the right fuselage
side assembly. When all notches and tabs are
aligned, apply glue and secure the two halves
together.
Note: Make sure the fuselage assembly is at on the
building bench. Weight the assembly down until the
glue cures to insure a straight fuselage.
c 11 Locate F1, note the dashed line at the bottom,
and sand the bottom to taper from back to front
down to the dashed line. is will conform to
the curve at the bottom of the fuselage side
when installing the fuselage bottom.
Here only half of the bottom of F1 has been beveled to the dashed
line to accommodate the curved bottom sheeting. Leave the tab
until after the sheeting has been attached.

Install and glue F1 to the fuselage assembly.
Use some scrap wood and rubber bands to
secure it until the glue cures.
c 13 Install BUT DO NOT GLUE formers F2, F3
and F4.
c 15 Test t FB making sure the tab on F5 engages
the notch provided. At the front the bottom
should lay at against F1 with the notch cen-
tered in the slot provided. When satised with
the t, glue Only F6 to FB taking care to insure
it is straight on the fuselage and square to F5
and let it cure thoroughly.
Two pieces of scrap wood are retained with a rubber band to hold
the side snugly against F1 until the glue sets.
c 16 Pull the sides in against each former F2, F3 and
F4 and glue the sides to the formers.
c 17 Pull the front of FB up snug against F1 and
glue it there.
c 18 Check that both fuselage sides are exactly the
same and snug against the formers when satis-
ed with this glue the bottom of F2 to FB. Pro-
ceed on to F3 and FB and nally F4 and FB.
Your fuselage sides should have equal amounts
of FB extending on each side.
Installing the fuselage bottom, a piece of scrap balsa is bev-
eled as required to provide the clamps a at surface to grip.
c 19 Glue the fuselage sides to FB.
c 20 Install and glue the Battery Tray (BT) to F1
through F4.
c 21 Cut two pieces of ¼” triangle stock 8-1/2” long
and glue one to each side of the fuselage at the
top of F1 through F3 and butt up to F4.
c 22 Cut two 13-1/2” pieces of ¼” triangle stock and
glue one to each side of the fuselage between
the side (FS) and the bottom (FB).
c 23 Cut a piece of ¼” triangle stock to t along the
sides at the windshield. Taper both ends to t
and then glue in place. Note that you will need
to cut and remove the ¼” triangle stock at the
notch in the fuselage side to allow next part to
be installed. Use the notch in the fuselage side
as your guide.
c24 Cut a piece of `1/8” x ¼” Basswood to t
across the fuselage and then glue it into the
notches at the base of the windshield
c 14 Locate MGM and install four #4-40 blind nuts
in the holes provided. Use the registration pins
to install and glue this to the inside (unlabeled
side) of forward fuselage bottom (FB).
MGM Installed on the inside of the fuselage bottom.

c 25 Pull the tail section together, carefully align the
fuselage sides and glue the tail section together.
c 26 Install and glue F7.
c 27 Install and glue F9 and F10 taking care to keep
the fuselage perfectly straight.
c 28 Cut two pieces of 3/16” square stock to 21-
1/2” long. Place them in the notches provided
on each side of F7 through F10 and taper as
required at the tail section. Glue these to the
fuselage sides and the formers taking care to
keep the fuselage straight.
c 29 Locate two F13 pieces. Install a ¼” x 1/8”
magnet in each of the four holes supplied, use
a liberal application of CA glue to retain the
magnets. Install and glue one F13 on each side
of the hatch area from F1 through F3. Don’t
worry about polarity at this time; we will take
care of that later.
Use thick CA to install all magnets. At this point polarity
does not matter, we will match the polarity later when we
install magnets in the hatch.
c 30 Cut two pieces of 3/8” triangle stock to 16”
long and install and glue to the top of the aft
fuselage and formers F8, F9 and F10. Taper
as required at the tail section. HINT: Cut both
pieces of triangle stock from the same stick,
this will improve the odds that both sticks will
be about the same stiness.
c 31 Locate and prepare the bottom sheeting, FB-1
through FB-7. Assemble these to make the
bottom sheet for the fuselage. This is best done
over a sheet of Parchment paper to prevent
sticking to the workbench. When assembled,
glue the bottom sheeting to the fuselage.
The top and bottom aft sheeting are both cut in several
section that should be assembled before installing. Note the
correct orientation for the top sheeting, the offset elliptical
opening should be on the left side of the fuselage.
Locate and assemble the top sheeting FT-1
through FT-5 in the same manner. When in-
stalling the top sheeting, insure that the slots in
the top sheeting are aligned with the slots in F9
and F10 and that labeled side is up. Install and
glue the top sheeting in place. Use a piece of
¼”” scrap wood to insure that the top sheeting
is aligned with the slot in F10. Trim out any of
the corner triangle stock in the elliptical push
rod opening.

Locate and prepare the pylon parts two PL-B
and one PL-A. Use the registration pins to lam-
inate a PL-B to each side of PL-A.
c 34 Install and glue the pylon to the fuselage
between F4 and F5. Insure that the tab at the
bottom engages the notch in FB.
Pylon assembly using the registration pins for accurate
alignment. The pylon will support the power pod as well as
provide hidden access for cabling.
c 35 Locate two F-13 Fuselage hatch frame. Install
and glue four 1/8” x ¼” magnets into the holes
provided. Medium or thick CA works best for
this step.
c 36 Install and glue the F-13 hatch frames to
formers F1 through F3.
c 37 Cut a piece of 1/8” x ¼” basswood stock to
2-1/2” long and install and glue it into the
notches provided at the aft end of the F13 rails.
c 38 8Cut a piece of 1/8” x ¼” basswood stock
to 4-1/8” long and install and glue it into the
notches provided in the fuselage sides at the
bottom of the windshield area.
Install and glue the windshield (WS) to F3, F4
and F5 and the fuselage sides.
The windshield and FST have been installed and the water
resistant hatch has been assembled. This photo shows the
nose cone installed however we will get to that a Little later.
Follow the steps described in step 48 to get the magnet
polarity correct.
c 40 Install and glue two FST parts to the top front
of the fuselage on both sides of the hatch open-
ing. Carefully align them to be ush with F13
c 41 Located and assemble the Fuselage Nose Cone
parts FNC-A, FNC-B and FNC-C.
c 42 Locate the 1-3/4” x 1-1/2” x ½” blocks. Place
them in position in the Fuselage Nose Cone
assembly and mark them for material removal.
Do the same for the 3/4” x 1-1/2” x 1-3/16”
blocks. Remove all excess material and then
glue the blocks to the Fuselage Nose Cone
assembly.
c 43 Glue the Fuselage Nose Cone assembly to F1,
make the assembly ush at the bottom at F1,
the top will stand proud of F1.
ABOVE: The four nose cone blocks have been marked and all ex-
cess material will be cut away prior to assembling the nose block.
LEFT: The nose block has been assembled and rubber bands are
used to hold the assembly together until the glue sets.

c 51
c 44 Carve and sand the nose cone to shape.
c 45 Locate and prepare hatch components HA
and HAR. Glue the hatch rails (HAR) to HA.
Insure that HAR are square to HA.
c 46 Using the registration pins, install and glue
HA-B to the hatch assembly. Note that the
arrow on HA points forward.
c 47 Locate four 3/32” x ¼” magnets and allow one
to attach itself to each of the four magnets in
F13. They will naturally orient themselves for
correct polarity. Now use a felt tip pen to mark
the side of each magnet facing in toward the
center of the fuselage. Install and glue each
magnet in the appropriate hole in the hatch
rails (HAR) with the marked side facing in-
ward toward the center of the fuselage.
This method of producing the nose cone makes it easy to
maintain symmetry and reduces much of the carving need-
ed.
c 48 Locate prepare and assemble the stabilizer
parts S1, S2 and S3.
c 49 Locate prepare and assemble the vertical n
parts V1, V2 and V3.
c 50 Glue the vertical n assembly to the stabilizer
assembly. Use the square to insure that the n
is at 90° to the stabilizer. Cut two pieces of ¼”
triangle stock and glue them at the interface of
the vertical n and the stabilizer.
Place the fuselage assembly on the building
bench and weight it down to insure that it is
setting perfectly at on the bench.
Vertical n sections ready to be assembled. After gluing up
sand out any imperfections as it is easier to do it while you
can lay it at on the bench.
c52 Install and glue the vertical n and stabiliz-
er assembly to the fuselage. Insure that the
stabilizer is perfectly parallel with the building
bench top.
c 53 Install and glue V4 to the top of the stabilizer.
c 54 Cut a 24” length of the red outer tubing of Ny-
Rod Push it through the hole in the top sheet-
ing at the leading edge of the vertical n and
rout it through the right side of F8.
c 55 This tube will glue to the leading edge of the
vertical n, start at the top of V4 and use thin
CA to glue it. Keep it centered on the vertical
n leading edge.
Use the building square to insure that the vertical n is in-
stalled perfectly square to the stabilizer. Reinforce the joint
with 1/4” triangle stock.
Cut two pieces of ¼” triangle stock and install
and glue it to both sides of the vertical n at
the fuselage top. Extend it forward to include
the Ny-Rod tubing.

Clever use of the Ny-Rod elevator pushrod which also be-
comes the leading edge of the vertical n. Use thin CA and
kicker to attach this part. Fill the gap between the pushrod
and the n with wood ller.
Trim away the triangle stock from the elliptical
pushrod opening on the top of the fuselage and
taper it aft to accommodate the Ny-Rod when
installed.
After installing the triangle bracing at the bottom of the verti-
cal n, open up the pushrod hole, angle it aft.
If you haven’t already determined whether
your going to use electric or glow power,
now is the time to decide. In this case we will
be building the electric version. Locate the
rewall parts FW-E (E for electric and G for
glow), using the registration pins, laminate the
two pieces together.
Note that one side of the rewall assembly has
two ¼” holes in it at opposing corners. Install
a 3/32” x ¼” magnet in each hole. This side
will be the front of the rewall, facing for-
ward.
Install triangle stock at the base of the vertical n
and fair it in the front to match the contour of the
Ny-Rod.
FRONT BACK
Here the electric rewall has been laminated together and
the 1/4” magnets installed. The glow rewall is assembled in
the same manner.
c 60 Locate and prepare the power pod base (PB)
and the two sides (PS). NOTE: The power pod
sides will be separated later. For now, keep the
two sections as one. Assemble and glue the
power pod base, sides and the rewall togeth-
er. Note that the large notch in the rewall is
on the bottom and should align with the large
notch in the power pod base.
Install a 2-3/4” piece of ¼” square balsa into
the notch at the aft end of the power pod
assembly. Plane or sand it to contour with the
sides.
c 62 Cut a piece of 1/8” x 1-1/4” x 2-3/4” piece of
basswood and glue it to the notch at the top
forward of the hatch side. Take care not to
glue it to the hatch side.

Locate and assemble the hatch top PHT-A,
PHT-B and PHT-C. Glue this assembly to the
top of the hatch aligned ush with the 1/8: x
1/4” piece at the front of the hatch. Do not re-
move the dash cut rectangle at the front of this
assembly. This will be removed in a later step
for the electric version. It will remain in place
for the glow version. Form this assembly along
the top of the hatch sides and glue it to the ¼”
square at the aft end of the hatch. After it cures,
trim o the excess at the aft end.
Plain or sand a bevel to the 1/4” square balsa at
the aft end of the hatch to match the contour of
the hatch sides.
Install and glue a 1/8” x 1/4” x 2-3/4” piece of
basswood in the notch provided at the aft bot-
tom of the hatch.
Glue PHB to the aft end of the hatch sides, the
1/4” square balsa and the 1/8” x 1/4” basswood.
Note, for the glow version do not remove the
circular openings in PHB. These are cooling air
exits for the electric version.
There are four 1/16” tabs attaching the hatch
to the power pod sides, trim these tabs and re-
move the hatch.
Using the registration pins, install and glue a
(HAC) to the inside of each side of the power
pod.
Cut a 1/8” x 1/4” x 2-1/2” piece of basswood
and glue it into the notch provided at the aft
end of HAC.
Install and glue the pylon, insure that the tab at
the bottom engages the notch on (PB). Glue it
to PB, F4 and F5.
The hatch top sheeting is assembled above, note the dash cut open-
ing at the front of the assembly will be opened later on the electric
version only.
For the electric version only, open up the dash
cut rectangle in the top of the hatch and install
the printed air scoop.
c 73
c 72 Install and glue four 3/32” x 1/4” magnets into
the holes provided in HAC. Keep these ush to
the outside of HAC.
Place another 3/32” x 1/4” magnet against each of these magnets on the inside of HAC. Use a Sharpy
marker to mark the inside of each of these magnets to keep the correct orientation. Then install each of
these magnets into the hatch sides with the marked side inward. Be sure to put them in the matching loca-
tion on the hatch. Thick CA works best for this step.

Install and glue a 1/8” x 1/4” x 2-3/4” piece of
basswood in the notch provided at the top of
the top of the power pod just aft of the rewall.
This will glue to both sides of the power pod
and the top of the pylon.
Glue the power pod top (PT) to the rewall,
both sides and the 1/8” x 1/4” brace.
Cut three 12” long pieces of 1/8” square bass-
wood. Taper the leading edge and glue them
to the bottom of the forward fuselage bottom
using the alignment lines provided starting at
the step.
Optional Landing Gear Assembly
Locate MPG-A and two MGP-B parts. Use the
registration pins and glue the MGP-B parts to
MGP-A. Glue them to the unlabeled side of
MGP-A.
Registration pins are used to install MGP-A and MGP-B with the labeled
side of MPG-A down.
Use one registration pin and carefully align the
second hole and install and glue MGP-S to the
labeled side of the assembly of MGP-A.
MGP-S parts are glued to the MGP-A assembly.
Locate the 1/8” x 8-7/8” main gear axle and se-
cure it to the MGA assembly with two polycar-
bonate gear straps and four #2-1/4” sheet metal
screws. Install the wheels and secure them with
two 1/8” wheel collars.

The tail gear mount is assembled from two printed plastic part included. This assembly will replace the
water rudder when land operation is desired.
Locate the two tail gear mount halves and open
up the tail wheel axle hole with a 1/16” drill.
Drill the hole square to the sides of the mount.
To insure the axle is straight in the nal assem-
bly, place a 1” piece of 1/16” wire through the
axle holes and another one through the bolt
hole at the top of the assembly. When satised
that the axle is square to the sides, glue the as-
sembly together with thin CA. NOTE: debur
the ends of the wire for easy insertion into the
axle holes. This t must remain snug.
Plastic tail gear mount halves will replace the water rudder for land op-
eration.
Cut a piece of the 1/16” wire to the same
width as the gear mount and insert it into one
side, install the wheel and then push the axle
through to the opposite side. Retain the axle
with a dab of thick CA on both sides of the
assembly.
Two pieces of 1/16” music wire are used to assist in aligning the axle before
applying thin CA to the assembly. The axle shaft must be square to both
sides.
The completed tail gear assembly ready for land operation.
NOTE:
When installing the tail wheel assembly, re-
move the bolt holding the water rudder and
replace the water rudder with the tail wheel
assembly. Snug the retaining bolt up so the as-
sembly will remain in the retracted position.
10

c 72 Locate and assemble the rudder, use the
registration pins to laminate the three sections
together. NOTE: The water rudder is the clear
plastic part located in the parts bag. This water
rudder should be attached to the rudder with a
#2-56 bolt and Ny-Lock nut. It should be left
loose enough to kick up in the event of contact
with weeds or other objects. Also the rudder
should be water proofed with a coat of thinned
Epoxy resin before nal assembly.
c 1
The rudder is laminated from three sections, the ply center
section has cutouts for the hinges and the kick-up water
rudder is mounted to the bottom.
Now is a good time to assemble the Hinge Slotting jig. Use it to
cut the slots for the CA hinges in the trailing edge of the stabilizer
and the slots for the pinned hinges in the vertical n. Place the
jig against the edge to be slotted, keep the knife parallel to the
part and make several shallow passes until the desired depth is
reached. The hinge locations are marked on the elevator, transfer
these markings to the stabilizer and cut the slots. Place the pinned
hinges into the rudder and then use this to locate the slot locations
on the vertical n.
Wing Assembly
The wing plans may be used in one piece or
cut in half if desired. Place them on the work-
bench and cover them with waxed paper.
Locate and prepare the false leading edge
(FLE). Use a straight edge to align it with the
plans. Note that the alignment line at the root
end of the plans should align with the align-
ment line on the rst stando. Tack glue a
pinning to every other stand o and secure to
the bench with pins.
The wing leading edge is secured to the bench by tack gluing
pinning tabs to every other stando and securing with pins.
A straight edge is used to insure it is straight and it is aligned
with alignment lines on the plan and the rst stando.

c 2Locate and prepare ribs W1 through W10.
c 3Note that the labeling on the sheer webs is on
the root end. Carefully place ribs W2 through
W9 into the appropriate slot in the bottom
sheer web.
Slide the top sheer web onto the rib assembly
until the top and bottom sheer webs are ush
to each other top and bottom. Note that this
may require some patience. Remember nes
not force, when everything is lined up correct-
ly they will fall together.
c 5While holding the assembly in your hands,
press the two sheer webs together top and bot-
tom and apply a dab of CA in the glue ports.
The glue ports are the elliptical holes in the
sheer webs for gluing. Proceed down the sheer
web until the full length of the sheer webs has
been tack glued together.
ABOVE: All internal ribs are installed onto the bottom sheer
web.
BELOW: The top sheer web has been installed and now all
ribs are captive in the sheer web.
c 6Place a 3/16” x ½” x 24” basswood spar n
position over the plans.
c 7Place the leading edge tab of each rib into
the appropriate slot in the false leading edge
and down over the basswood spar. DO NOT
GLUT at this time.
c 8Slide the false trailing edge into position and
slide each rib into the appropriate slot. DO
NOT GLUE at this time.
c 9As you did on the false leading edge, line the
false training edge up with the alignment line
on the rst stand o and secure it to the build-
ing board with a pinning tab at every other
stand o.
c 10 Install and glue W1 to the false leading edge,
the sheer web assembly and the false trailing
edge. Make sure W1 is in good contact with
the sheer webs as they will set the correct
dihedral angle for W1
c 11 Now move down the wing and glue each rib
to the false leading edge, the false trailing
edge and the sheer webs. Make sure each rib
is rmly in contact with the adjoining parts
before applying glue.
c 12 While holding the sheer web assembly into
rm contact with the bottom spar, apply glue
to the entire length.

13
c 13 Mark and trim a 3/16” x ½” x 24” basswood
stick to the exact length required between W1
and W10. Use aliphatic resin glue to glue the
top spar to the wing assembly.
c 14 Cut a 6” length of cable tunnel tube and in-
stall and glue it to ribs W2 through W5.
c 15 Plane the false leading edge to contour with
the ribs in preparation for installing the top
leading edge sheeting.
c 16 Locate and prepare the top leading edge
sheeting (WTLES).
c 17 To install the top sheeting it is best to use two
types of adhesives, medium CA and aliphatic
resin. The medium CA will quickly attach
the sheeting to the top spar while the ali-
phatic resin will allow time to work with the
sheeting to form it to the ribs. Apply aliphatic
resin to the false leading edge and all the ribs
between the spar and the leading edge. Apply
thick CA to the length of the top spar. Place
the top leading edge sheeting in place, cen-
ter the cap rib openings on the ribs and then
press the sheeting into contact with the spar
until the CA has cured. Now use weight, tape
or pins to bring the top sheeting into contact
with the ribs and the false leading edge until
the glue has cured.
The false leading edges is beveled to contour with the wing
ribs in preparation for installing the top leading edge sheet-
ing.
The top and bottom sheeting are installed in the same
way, using medium CA along the spar for a quick cure and
aliphatic resin an all remaining ribs and false leading edge to
allow time to work. Tape is used to secure the sheeting until
the aliphatic resign glue sets.
c 18 Locate and prepare the top center section
sheeting (TC-A and TC-B). Glue the two
together. Then glue the assembly to ribs W1
through W4 between the spar and the trailing
edge. Note that the trailing edge is slightly
larger to t the width of the false trailing
edge.

14
c 19 Locate prepare, install and glue all the top
cap strips, they are located on sheet #14 and
the top cap strips are labeled with a T.
Here the bottom leading edge and center section sheeting
have been installed and tape is used to secure the sheeting
until the aliphatic resin has set.
c 20 Remove the wing assembly from the plan and
turn it over. Snap o all the standos on the
false leading edge and the false trailing edge.
Save the pinning tabs for the remaining wing
half.
c 21 Taper the false leading edge to contour with
the ribs.
c 22 Locate, prepare and install the bottom leading
edge sheeting in the same manner as you did
the top sheeting. Use strips of masking tape
to secure the leading edge.
c 23 Locate and assemble the bottom center sec-
tion sheeting (BC-A and BC-B)
c 24 Install and glue the bottom center section
sheeting.
c 25 Install and glue the ply-reinforcing ring
around the servo lead hole.
c 26 Install and glue the servo mounting rails
(SMR). The side with the screw holes should
be facing each other.
c 27 Assemble the bottom wing tip sheeting
(WTS-A and WTS-B). Install and glue it to
ribs W9 and W10.
c 28 Install and glue bottom cap strips to ribs W5
through W8, note that the cap strips on rib
W5 and W6 has a cut out in them for the
servo mounting plate, refer to the plans for
correct orientation. Note that the longer end
goes toward the leading edge.
c 29 To nish framing out the servo mount open-
ing, install and glue the two (SO) pieces at
the front and back of the opening. These
should butt up against the cap strips on W5
and W6.
c 30 Install and glue the trailing edge (TE) to the
false trailing edge. Use several pieces of 1/8”
dowel in the holes provided to insure accu-
rate alignment. These alignment dowels can
be left in permanently if desired.
W5-A and W6-A are installed as shown above, they will pro-
vide a ledge that the servo mount will rest on.
The ply servo mounts are installed between W5 and W6.

15
c 31Cut, install and glue the leading edge from a
piece of 3/8” x ¾” x 36” balsa stick. Use pins
and tape to secure it until cured.
Dowels are used to precisely position the trailing edge and
clamps secure it until the glue sets.
c 32 Sand the wing tip at if there are any pro-
trusions. Install and glue the wing tip (WT).
Use the gussets TWT-A and TWT-B on the
top and gussets TWB-A and TWB-B on the
bottom.
c 33 Install and glue the four ½” x 2-3/4” triangle
pieces to the trailing edge of the wing tip, top
and bottom.
c 34 Locate and assemble the oat parts Two TFS,
one TFK-A and one TFK-B. Glue TFK-A
and TFK-B to one of the oat sides TFS.
c 35 Glue the remaining oat side to the oat
assembly.
c 36 Locate and prepare the oat sheeting, parts
A,B,C and D. Assemble and glue parts A,B
and C.
c 37 Install and glue the aft sheeting section D.
c 38 Install and glue the forward sheeting assem-
bly, note that you may have to wet the sheet-
ing to make the bend without breaking. Use
Windex or water with ammonia in it to wet
the wood. The tip oats will be installed into
the slots provided in the wing sheeting how-
ever you may want to cover the wing and the
oats before attaching them to the wing
This completes this half of the wing construction,
return to step one of the wing construction and
repeat the assembly instructions for the remaining
wing section.
The wing tip and the wing tip gussets are installed. The
inset shows the triangle stock installed the trailing edge to
strengthen the wing tip.
Use the leading edge template to help in shaping the leading
edge.
ABOVE: Pontoon construction begins with the as-
sembly of TFK-A and TTFK-B, then the sides are
installed. RIGHT: The pontoon assembly ready for
sheeting. Tabs will position it on the bottom wing
sheeting.

Assembling the wing halves
c 1Locate, prepare and laminate the wing hook
parts (WH) using the registration pins.
Cut two 1/8” x 1” dowels and place them in
the alignment holes. Glue them to the WH
assembly protruding equal amounts on both
sides.
c 3Test t the WH assembly to both wing
halves. When satised with the t, glue the
WH assembly to one wing half and then glue
the remaining wing half to WH.
c 4Laminate the two TEX parts together; note
that the labeling should be on the outside of
the parts. Bevel the leading edge slightly to
t. Place the wing onto the fuselage and cen-
ter it. Glue the TEX assembly to the trailing
edge taking care to keep it centered.
Use a mixture of Z-Poxy thinned with dena-
tured alcohol to apply the 3” wide berglass
cloth. Lay the cloth in position and then
brush on the nishing resin mixture. Don’t
be alarmed if the cloth appears to have a
dry look, most of the resin will soak into the
wood but it will adhere the glass cloth to the
wing.
The wing hook assembly with dowels installed, ready to join
the wing halves.
Te servo mounting plate should t snugly to help waterproof
the servo and wing assembly.
Laminate the two trailing edge extensions (TEX) using the pin
registration system, keep the labeled sides out.
Aileron servo showing the servo mount installa-
tion. Use plenty of CA one the ply mounts.

Aileron assembly
Locate and prepare the aileron base (AB).
Place it on the bench with the labeled side
up. This will insure a left and a RIGHT ai-
leron. Work over waxed or parchment paper
and install and glue the leading edge (ALE).
Insure that it is aligned wit the leading edge
of AB and glue it.
c 2Install and glue the tip ribs (A1).
c 3Install and glue all remaining ribs (A2).
c 4Install and glue the aileron horn block
(AHB). Note that the notch in AHB should
line up with the slot on AB.
c 5Taper the leading edge and the aileron horn
block to contour with the ribs, do not taper
the tabs yet.
c 6Install and glue the top sheeting (AT).
The aileron horn should be installed after
covering the ailerons. After the ailerons are
installed and the linkage has been installed
and adjusted, install and glue the splash
guards over the servo openings in the wings.
Aileron assembly underway, on the right is the rough as-
sembly, on the left the leading and trailing edges have been
tapered to contour with the ribs in preparation for installing
the top sheeting. The aileron horns should be installed after
covering the ailerons.
