GPMA4151 Canopy
GPMA4152 Decals
PREPARATION
1. Lay three or four paper towels over each other and cut
the stack into small squares.The small paper towel squares,
dampened with denatured alcohol, will come in handy for
epoxy cleanup and other general cleanup during assembly.
2. Remove the masking tape holding all the control surfaces
to their main parts. If necessary, clean off any residual tape
glue with a couple of your paper towel squares dampened
with naptha (lighter fluid).
3. Using a sealing iron, remove any wrinkles in the covering
before assembly.
ASSEMBLE THE WING
1. Using 220-grit sandpaper, remove any excess glue from
the sides, top and bottom of the aluminum and plywood wing
joiner. Clean the wing joiner with denatured alcohol and a
paper towel.
2. Checkthe fit of the wingjoiner in the wingpanels.Remove
any excess material from the joiner to allow the panels to fit
together.Gather everything required for gluing the wing joiner
and wing together, including 30-minute epoxy, mixing sticks,
epoxy brush, 12" [304mm] long dowel or wire, denatured
alcohol and paper towels.Mix up 1/2 oz.[14.8cc] of 30-minute
epoxy. Working quickly, pour a generous amount into the
joiner pocket of one wing half. Use your wire or dowel to
thoroughly distribute the epoxy, coating all surfaces inside
the joiner pocket. Coat the root rib and one half of the wing
joiner that goes into the wing. Insert the joiner in the wing.
Coat the joiner pocket in the other wing half and the other
end of the wing joiner. Join the wing halves together. Then,
stand the wing on end with one of the wing tips resting on
the floor. Use a piece of R/C foam or something similar to
cushion and stabilize the wing so it won’t slide around. Hold
the two wing halves together with masking tape.Wipe off any
excess epoxy with a paper towel dampened with denatured
alcohol. After the epoxy has hardened, apply the included
white tape around the joint.

INSTALL THE FIN
1. Use a felt tip pen to draw a centerline on the top aft end
of the fuselage. Draw a line 3/32" [2.4mm] on both sides of
the centerline. Position the fin on the fuselage and mark on
the top of the fuselage, all the way around the fin.
2. Using a hobby knife with a fresh blade, cut and remove
the covering only between the two outside lines. DO NOT
cut the wood under the covering as this will weaken the
structure. Also, insert the fin in the fuselage and mark the
tail post where it exits the fuselage.Trim the covering from
the tail post and alignment tab.
3. Insert the elevator control cable into the nylon outer
control tube in the fuselage and the fin.Apply petroleum jelly
to the cable to insure epoxy doesn't adhere to it. Position
the fin on the fuselage and move the cable to check that it
moves freely.
4. Use 6-minute epoxy to glue the fin to the top of the
fuselage. Wipe off the excess epoxy with a paper towel
dampened with rubbing alcohol. Use masking tape to hold
the fin in position, aligned with the centerline of the fuselage
and parallel to the sides.
Drill a 3/32" Hole
1/2" Deep, in the Center
of the Hinge Slot
5. Drill a 3/32" [2.4mm] hole, 1/2" [13mm] deep, in the
center of the fin and rudder hinge slots.If you use a Dremel®
Rotary Tool for this task, it will result in a cleaner hole than if
you use a slower speed drill. Drilling the hole will twist some
of the wood fibers into the slot, making it difficult to insert the
hinge. Insert a hobby knife blade in the slot, working it back
and forth a few times to clean out the slot.
Temporary Pin
to Keep Hinge
Centered
6.To keep the hinges centered, insert a pin in the center
of the hinges.

5
7. Insert three hinges in the rudder and attach the rudder to
the fin.Remove the pins, making sure there is approximately
a 1/64" [0.4mm] gap between the rudder and fin.
Assemble, then Apply 6 Drops
of Thin CA to the Center of
the Hinge, on Both Sides
8. Deflect the rudder 1-1/2" [38mm] in one direction and
apply six drops of thin CA to the center of the hinges.Deflect
the rudder in the other direction and again apply six drops
of thin CA to the center of the hinges. Use a paper towel to
absorb excess CA from the hinge gap before it hardens. Do
not use CA accelerator.Allow the CA to harden slowly.
INSTALL THE STABILIZER
1.Draw a centerline on the bottom of the stabilizer. Draw
a line 3/32" [2.4mm] on each side of the centerline. Use a
hobby knife to cut and remove the covering only between the
two outside lines. DO NOT cut the wood under the covering
as this will weaken the stabilizer, causing it to fail.
2. Use 6-minute epoxy to glue the stabilizer to the top of the
fin.Use a square to check that the stabilizer is perpendicular
to the fin.
3. Position the two stabilizer supports under the stabilizer
against the fin. Mark the outline of the supports on the fin
and stabilizer. Use a sharp hobby knife to trim and remove
the covering 1/16" [1.5mm] inside the outline.
4. Use 6-minute epoxy to glue the stabilizer supports to
the fin and stabilizer.
5. Install the elevator using the same hinging method used
on the rudder.

6
INSTALL THE RADIO SYSTEM
1. Separate the back plate from one of the nylon control
horns. Thread a nylon clevis 14 turns onto the 2-56 metal
pushrod. Slide a silicone clevis retainer over the end of the
clevis. Attach the clevis in the third hole from the bottom of
the control horn.
Hinge Line Hinge Line
CORRECT INCORRECT
Hi
2. Use a sharp hobby knife to remove the covering from
the end of the rudder guide tube. Insert the pushrod into the
rudder pushrod guide tube. Position the control horn on the
rudder so that the four holes in the control horn are aligned
with the hinge line.Drill two 3/32" [2.4mm] holes through the
rudder using the control horn as a guide.Remove the control
horn and harden the holes by applying two or three drops of
thin CA in each hole.After the CA has cured, attach the control
horn to the rudder using two 2-56 x 3/8" [9.5mm] screws and
the control horn back plate.
3. Use a #44 or 3/32" [2.4mm] drill bit to enlarge the outer
hole in the second nylon control horn.
4. Insert the quick connector through the previously drilled
hole in the control horn. Install a 2mm washer on the quick
connector. Put a drop of threadlocker on the threads and
secure the quick connector with a 2mm thumb nut.Tighten
the nut and then slowly back it off until the quick connector
rotates freely. The threadlocker will prevent the nut from
coming loose.
5. Slide the elevator cable through the hole in the quick
connector and position the elevator control horn so that the
four holes are aligned with the elevator hinge line.Use a felt
tipped pen to mark the location of the holes.

7
6. Drill two 3/32" [2.4mm] holes through the elevator using
the control horn as a guide. Remove the control horn and
harden the holes by applying two or three drops of thin CA
in each hole. After the CA has hardened, attach the control
horn to the elevator using two 2-56 x 3/8" [9.5mm] screws
and the control horn back plate.
Servo
Grommet
Brass Eyelet
Servo Tray
Screw
7. Install the servos using the hardware included with your
radio system. Again, apply a couple of drops of thin CA to
harden the screw holes.
8.Wrap the receiver and receiver battery in 1/4" [6.4mm]
thick foam. Position the receiver and receiver battery in the
fuselage as shown. Remove the receiver switch cover from
the receiver switch. Position the switch cover on the outside
of the fuselage, between the receiver and receiver battery.
Mark the two mounting screw holes and the switch opening
on the fuselage.Use a sharp hobby knife to cut out the switch
opening and a 3/32" [2.4mm] drill bit to drill out the screw holes.
Mount the receiver switch on the inside of the fuselage with
the switch cover on the outside.
9. Switch on thetransmitter and receiver.Center the elevator
and rudder trims on the transmitter. Remove the servo arm
screw and position the servo arm so that it is perpendicular to

8
the centerline of the servo. Cut the servo arm so it does not
touch the fuselage side, approximately 7/16" [11.1mm] from
the center of the arm.Remove the unused arms and reinstall
the servo arm.Reinstall the servo arm screw.With the rudder
centered and rudder aligned with the fin, mark the pushrod
wire at the servo arm.
10. Bend the wireup at the mark.Cut the wire5/16" [7.9mm]
above the bend. Secure the pushrod to the servo arm with
a nylon FasLink™ . Make sure the FasLink does not hit the
fuselage side or bind against the servo arm.
11. Slide the two plywood outer pushrod tube supports
over the elevator outer pushrod tube.
12. Center the elevator servo. Trim a servo arm to fit
perpendicular to the elevator servo.Remove the other unused
servo arms.
13. Install a quick connector on the elevator servo arm
following the same procedure used to install it on the elevator
control horn.
14. Install the servo arm on the elevator servo.Route the
elevator cable through the quick connector on the elevator
control horn and the elevator servo arm. Apply a drop of
threadlocker on a 3 x 5mm machine screw.Install the machine
screw in the quick connector on the elevator control horn and
tighten it against the elevator cable.
15. Use CA to glue the two plywood elevator outer tube
supports in the slots in the fuselage side.

9
16. Center the elevator servo arm and the elevator.Apply
a drop of threadlocker on a 3x5mm machine screw. Install
the machine screw in the quick connector on the elevator
servo arm and tighten it against the elevator cable. Trim off
the excess cable.
FINISH THE SAILPLANE
1. Use 6-minute epoxy to glue the nylon tail skid on the aft
bottom of the fuselage.
2. Remove the covering from over the wing dowel holes.
Center the wing dowels in the fuselage. Use thin CA to glue
them in position.
CANOPY INSTALLATION
1. Paint the cockpit with the color scheme of your choice.
Test the paint on a piece of plastic that was cut off of the
cockpit to make sure it will not affect the plastic. RC car
paints usually work well for this. Do not paint the edges of
the cockpit where the canopy will attach or the glue will not
hold as well.After the canopy is glued on, the canopy frame
decal will cover the glue joint.After the paint has dried, apply
the instrument decal to the instrument panel.
2. Using a needle nose pliers, open the eyelet slightly
so that a rubberband can be installed on the eyelet.Thread
each eyelet into the round plywood doubler until it just starts
to come out the back.
3. Use medium CA to glue one of the eyelets to the bottom
of the fuselage between the receiver and receiver battery.Glue
the second eyelet on the bottom of the cockpit aligned with
the eyelet in the fuselage.After the CA has hardened, thread
the eyelets in three or four turns more.
