Introduction
The FuntanaX 50 can do it all—harriers, torque rolls, blenders, and almost anything else you can dream up. It’s all
possible, thanks to an extremely lightweight, all-wood airframe and big control surfaces that give the FuntanaX 50 a very
impressive thrust-to-weight ratio and crisp control authority at any airspeed. The genuine UltraCote® trim scheme and
factory painted parts, such as the cowl and wheel pants, complement the performance perfectly.

Using the Manual
This manual is divided into sections to help make assembly easier to understand, and to provide breaks between each
major section. In addition, check boxes have been placed next to each step to keep track of each step completed. Steps
with a single box () are performed once, while steps with two boxes () indicate that the step will require
repeating, such as for a right or left wing panel, two servos, etc. Remember to take your time and follow the directions.
Before Starting Assembly
Before beginning the assembly of the FuntanaX 50, remove each part from its bag for inspection. Closely inspect
the fuselage, wing panels, rudder, and stabilizer for damage. If you find any damaged or missing parts, contact the
place of purchase.
If you find any wrinkles in the covering, use a heat gun or sealing iron to remove them. Use caution while working around
areas where the colors overlap to prevent separating the colors.

Required Parts
• Wing • Fuselage
• 1/4-20 x 2" nylon bolt (2)
• Horizontal stabilizer • Elevator
• Carbon fiber tail support rods
Required Tools and Adhesives
• Thin CA • 30-minute epoxy
• Flat blade screwdriver • Sandpaper
• Drill bit: 1/16" (1.5mm) • Drill
• Felt-tipped pen • Square
• CA hinge (6) • Paper towel
• Rubbing alcohol • T-pin
• 6-minute epoxy
Step 1
Place the wing onto the fuselage. Secure the
wing using the 1/4-20 x 2" nylon bolts.
Step 2
Measure and mark a centerline on the
stabilizer using a felt-tipped pen.
Step 3
Locate six CA hinges. Place a T-pin
in the center of each hinge.
Section 1: Stabilizer Installation

9
Step 4
Drill a 1/16" (1.5mm) hole in the center of each hinge
slot. Drill holes for both the elevator and stabilizer.
Step 5
Place the hinges in the elevator, resting the
T-pins against the leading edge of the elevator.
Step 6
Slide the stabilizer and elevator together. Check that the
elevator can move without interference from the stabilizer.
Use tape at each tip to hold the two together. Do not
use CA or any other glue on the hinges at this time.
Step 7
Slide the stab into the fuselage. Center the stab
in the opening by measuring the distance from
the fuselage to each tip. The stab is aligned
when both measurements are identical.
Step 8
Check the distance from each stab tip to each
wing tip. Remember to measure right-to-right,
left-to-left. It won’t work the other way around.
These measurements must also be equal.
Section 1: Stabilizer Installation

10
Step 9
The last alignment step is making sure the wing
and stabilizer are parallel. If they are not, lightly
sand the opening in the fuselage for the stab
until the stab rests parallel to the wing.
Parallel
Step 10
Use a felt-tipped pen to trace the outline
of the fuselage on the stab.
Step 11
Remove the stabilizer from the fuselage, and the
stabilizer from the elevator. Use a hobby knife
with a brand new blade to remove the covering
1/16" (1.5mm) inside the lines just drawn.
Note: Use care not to cut into the underlying
wood and weaken the structure. Doing so
will almost guarantee stab failure in flight.
Hint: A soldering iron or hot knife can be used
as an option to the standard hobby knife.
Cool Tip: Use a little rubbing alcohol and
a paper towel to remove those felt-tipped
marker lines once they are no longer needed.
Step 12
Double-check the alignment, to verify it’s correct. Mix up
1/2 ounce (15 ml) of 30-minute epoxy. Apply the epoxy to
the exposed wood of the stabilizer and into the slot in the
fuselage. Slide the stabilizer into position and remove any
excess epoxy using a paper towel and rubbing alcohol.
After the epoxy fully cures, apply a thin bead of epoxy
to the joint to fill any gaps and to fuel-proof the joint.
Step 13
Roughen up about 1/4" (6mm) of each end of the
carbon tail support using sandpaper. Test fit the carbon
tail support into the hole drilled in the fuse and notch
in the stabilizer. Use 6-minute epoxy to glue the rod
into position. Install both carbon tail supports.
Section 1: Stabilizer Installation

11
Required Parts
• Wing • Fuselage
• Vertical stabilizer
Required Tools and Adhesives
• 30-minute epoxy • Sandpaper
• Square • Ruler
The vertical stabilizer (fin) is a bit easier to install than the
stab. There is still some alignment that must be done, but
it is a lot less tricky.
Step 1
Locate the vertical stabilizer (fin) and slide it into
position. Position the fin so it aligns with the aft end
of the fuselage. Use a ruler to check the alignment.
Step 2
Check the alignment between the fin and stab.
The fin must be 90 degrees to the stab to be in
alignment. Sand the opening in the fuselage slightly
if necessary to get the perfect alignment.
Step 3
Use a ruler to draw two lines from the end of the slot
onto the fuselage as shown. Use a sharp hobby knife
to remove the covering from between the lines.
Step 4
Mix 1/2 ounce (15ml) of 30-minute epoxy. Apply the
epoxy to the tab on the fin and to the area on the top of
the fuselage where the covering was removed. Position
the fin in the slot and check the alignment. Use masking
tape to hold the fin in position until the epoxy fully cures.
Cool Tip: Use rubbing alcohol and a paper
towel to clean up any excess epoxy. Remember,
this only works before the epoxy cures.
Section 2: Vertical Fin Installation

12
Required Parts
• Wing • CA hinges (10)
• Aileron (left and right)
Required Tools and Adhesives
• Thin CA • T-pins
• Drill bit: 1/16" (1.5mm) • Drill
We recommend that you use the hinges provided.
They work extremely well when installed as described.
Even though the ailerons are large, we had absolutely
no problems.
Step 1
Locate 5 of the CA hinges. Place a
T-pin in the center of the hinges.
Step 2
Drill a 1/16" (1.5mm) hole in the center of each
hinge slot on both the aileron and wing.
Step 3
Place the hinges in the precut slots in the
aileron (or wing if you prefer). The T-pin will rest
against the edge when installed correctly.
Step 4
Slide the aileron and wing together. The gap
between the aileron and wing should be infinitely
small, approximately 1/64" (.4mm).
Step 5
Use a ruler to align the end of the aileron to the wing.
The aileron should set back away from the ruler slightly.
If not, they will interfere with the side force generators
when they are in place on the wing tips. Also check the
gap between the wing and aileron at the root, which
should be about 1/32"–1/16" (.8mm–1.5mm).
Section 3: Hinging the Ailerons

13
Note: Do not use CA accelerator during
the hinging process. The CA must be
allowed to soak into the hinge to provide
the best bond. Using accelerator will not
provide enough time for this process.
Step 6
Remove the T-pins from the hinges. Deflect the
aileron and apply thin CA to each hinge. Make
sure the hinge is fully saturated with CA. Use a
paper towel and CA remover/debonder to clean up
any excess CA from the wing and/or aileron.
Step 7
Firmly grasp the wing and aileron and gently pull
on the aileron to ensure the hinges are secure and
cannot be pulled apart. Use caution when gripping the
wing and aileron to avoid crushing the structure.
Step 8
Move the aileron up and down several times to work
in the hinges and check for proper movement.
Step 9
Repeat Steps 1 through 8 for the remaining aileron.
Section 3: Hinging the Ailerons

14
Required Parts
• Fuselage assembly • CA hinge (3)
• Elevator (left and right) • Rudder
• Tail wheel assembly • Fuselage filler
Required Tools and Adhesives
• Thin CA • T-pins
• Medium sandpaper • Hobby knife
• 6-minute epoxy • Petroleum jelly
Step 1
If you haven’t done so, slide the elevator and stab
together. Double check that the elevator can move
without interfering with the stabilizer.Check to make
sure the elevator can move freely. It should not
rub against the stabilizer towards the tips. Apply
thin CA to both sides of the hinge. Make sure to
saturate the hinge and don’t use accelerator.
Step 2
Once the CA has fully cured, give the elevator and stab
the tug test to make sure the hinges are well glued.
Flex the elevator a few times to break in the hinges.
Step 3
Apply a light coat of petroleum jelly onto the tail gear wire
where the bearing will ride. This is done to prevent the
epoxy from sticking to the wire and bearing, which would
make it a little difficult to steer or even use the rudder.
Step 4
Mix 1/2 ounce (15 ml) of 6-minute epoxy and
apply it to both the tail gear bearing and the slot in
the fuselage. Install the bearing. Use a paper towel
and rubbing alcohol to remove any excess epoxy
from the tail gear wire, bushing, and fuselage.
Section 4: Rudder and Elevator Installation

15
Step 5
Locate the last three CA hinges, and place
T-pins in the center, as was done for the ailerons
and elevator. Install the hinges in the rudder.
Step 6
Test fit the rudder to the fuselage. Make sure the tail gear
wire goes into the rudder, and that the rudder will rest
tight against the fin and fuselage. The tail gear bearing
should not interfere with the rudder. If it does, fix it.
Step 7
Mix 1/2 ounce (15 ml) of 6-minute epoxy. Remove
the rudder and place the epoxy only in the hole,
not in the groove. Epoxy in the groove will
probably make it difficult to use the rudder. Install
the rudder as described in the previous step.
Cool Tip: You can combine the
previous step with the following step
if you like. This will hold the rudder
in position while the epoxy cures.
Step 8
Check to make sure the rudder moves freely. It should
not rub against the fin at the tip. Apply thin CA to both
sides of the hinge. Make sure to saturate the hinge,
and don’t use accelerator. Use a paper towel and CA
debonder/remover to clean up any excess CA.
Step 9
Once the CA and epoxy has fully cured, give the rudder
and fin the tug test to make sure the hinges are well
glued. Flex the rudder a few times to break in the hinges.
Step 10
This section is completed by using thin CA
to glue the fuselage filler into position.

This way you can get to them later to
position the wheel on the axle.
Step 4
Attach the wheel pant to the landing gear
using a 4-40 x 1/2" socket head screw.
Section 5: Wheel Installation

17
Step 5

Step 1
Attach the engine mount to the firewall
using four 6-32 x 3/4" screws.
Step 2
Position the engine on the mount. Adjust the engine
so the distance from the firewall to the drive washer is
41/2" (114mm). Use a clamp to hold the engine in
position. Mark the locations for the engine mounting bolts.
Note: It may be necessary to remove
the carburetor from your engine and
rotate it so the needle valve faces
towards the top of the fuselage.
Step 3
Remove the engine and drill the locations marked in
the previous step using a 3/32" (2.5mm) drill bit.
Cool Tip: Use a drill press for the best
results. This makes holes perfectly
perpendicular (square) to the mount.
Section 6: Engine Installation

19
Step 4
Attach the engine using four #6 x 5/8"
socket head sheet metal screws.
Cool Tip: Apply a little bar soap to the
threads of the screws to make them easier
to thread into the mount. You can also
remove the mounts and run the screws
through, reattach them to the firewall,
and then bolt the engine down.
Step 5
Determine the proper location for the throttle pushrod.
Mark the location with a felt-tipped pen and drill the
firewall for the pushrod tube using a drill and 5/32"
(4mm) drill bit. Remove the engine if necessary.
Step 6
Test fit the throttle pushrod tube through the firewall
and into the fuselage. Once satisfied with the fit,
roughen the tube using sandpaper. Slide the tube back
into position and use medium CA to glue it to the
firewall. Allow 1/8" (3mm) of the pushrod to extend
forward of the firewall. Trim the throttle pushrod at the
front edge of the doubler on the throttle servo tray.
