The new Wattage Super Impress II EP ARF has pushed the performance envelope for the Impress lineage of model aircraft. This updated design
makes the Super Impress II EP ARF perfect for today's electric model enthusiast.
First, we made it lighter. Our factory has gone back to the drawing board to re-engineer the airframe from cowling to rudder, wing tip to wing tip.
More lightening holes, less wood overall, and balsa substituted for heavier woods, have produced a strong, but significantly lighter airframe. We
then complete the model with a lightweight proprietary covering material that provides a professional finish, yet retains the repairability you expect
from a wood airframe aircraft. We even include extra covering material for mishaps and dings from those less-than-friendly flying sites. The molded
cowling is prepainted and the molded wheel pants are prejoined. The windows are even molded and cut to shape for easy installation.
The Super Impress II EP ARF is accessorized with quality hardware and that you'd choose yourself for a model of this size. We use custom mini
control horns, adjustable clevises and matching threaded pushrods for convenience and easy adjustment. The main landing gear is now formed
aluminum instead of the older style metal rods.
In the air is where it really counts and the Super Impress II EP ARF is designed to "Impress" even the most experienced pilot. The range of motors
and performance available from the aircraft is staggering. With the Wattage 370 power system and a 5/4AAA NiMH flight battery, the Super
Impress II EP ARF makes a great aileron trainer and an easy Sunday-Flyer at a wing loading of under 10 ounces per square foot. This power
system is amazing for it's weight and size and it flies this 300 square inch-wing aircraft like a trainer! But, step up to a 480 brushless motor, larger
cells (or Lipo's) and matching propeller and ESC, then increase the control throws and watch out! Your friends will be amazed at the maneuverability
and performance of this beautiful aircraft. And, more importantly, you'll be having a blast flying battery after battery! From mild to wild, the Super
Impress II EP ARF will make an impression on you!

The Super Impress II EP ARF can be flown using a variety of different power systems. Motor mount plates are included for both gear
drive motors and direct drive motors.
For slow, trainer-like performance, the airplane will fly very nicely using the Wattage 370 power system with 3.67:1 gear box and
7.5 x 5 propeller. Combined with the Wattage 8 cell 5/4AAA 800mAH NiMH flight battery and the Wattage IC-15A Micro ESC, you
can expect about 8 minutes of smooth, slow and docile flying enjoyment.
If you want more power and faster speeds, then we recommend using the Wattage Super 400 Cobalt Direct Drive motor with an
APC 7 x 4 propeller. Matched with the Wattage 7 cell CP1300 NiCD flight battery and the Wattage IC-30A Micro ESC, this power
system will provide enough power for aerobatics and impressively fast flight speeds. As an alternative, you could use the Wattage
Super 400 Cobalt Direct Drive motor with the Wattage Inline 400 Gear Box and an APC 11 x 7E propeller, along with the Wattage
8 cell 2/3A 1100mAH NiMH flight battery and the Wattage IC-30A Micro ESC. This combination will provide more vertical
performance and longer flight times than the direct drive setup.
This section describes our recommendations to help you in deciding which types of accessories to purchase for your new
Wattage Super Impress II EP ARF. Please read through this entire section very carefully. We have provided you with tips
and recommendations that, if followed, will result in a great flying airplane. Failure to follow our recommendations may
result in a poor flying airplane.

✦✦
✦IMPORTANT✦✦
✦✦
✦When choosing accessories for your Super Impress II EP ARF, such as servos, ESC, receiver and other
related accessories, it's very important to take the weight of these items into consideration. Remember, the lighter the overall
weight of the finished airplane, the better the airplane will fly.

Many different power systems can be used to fly the Super Impress II EP ARF. Feel free to experiment with different brushless
motors, Lithium Polymer flight batteries and any of the other new and cool electric products that are becoming available.
Below we list just one of the more exciting alternative power systems we tested with the Super Impress II EP ARF. With this power
system the airplane was an absolute blast to fly!
Motor: Multiplex Permax BL-480 6D (480 size, 6-turn direct drive)
Propeller: APC 7 x 5E
Flight Battery: 3 Cell Lithium Polymer
ESC: Any brushless ESC capable of handling 25 amps or more
For longer flight time, the Wattage 3 Cell 2000mAH LiPO battery # 128783 works very well. We also used the Tanic 3 Cell
1550mAH LiPO and the Multiplex 3C 1250mAH LiPO with good success.
Alternative Power System Suggestions
The servos you use should be the lightest available, yet still have an adequate amount of torque. We suggest using servos that
weigh no more than 0.34 ounces and have a torque rating of no less than 11 ounces per square inch. Cirrus CS-4.4, Cirrus CS-5.4
and Cirrus CS-6.5 servos would be a perfect choice. Although a little heavier, Cirrus CS-09 servos and Hitec HS-55 servos would
also work well.
You will need to use a 4 or more channel radio system. The receiver should be as light as possible, preferably 1/2oz. or less. Most
four-channel micro receivers would be a good choice. We personally suggest using the Cirrus MRX-4II, the Hitec 555 Micro or the
Hitec Electron 6 Micro. If you do use one of the Hitec receivers, we suggest removing the case to reduce the receiver's weight. If
you do remove the case from your receiver, we strongly suggest wrapping the receiver with heat-shrink material to protect the
internal components.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The MRX-4II receiver has a range of approximately 500 yards (~1/4 mile). Keep this in mind when flying the
airplane while using this receiver.

The covering material used on the Wattage Super Impress II EP ARF is real iron-on, heat-shrink covering material, not cheap
"shelf paper." Because of this, it is possible with heat and humidity changes that the covering on your airplane may wrinkle or
sag. This trait is inherent in all types of heat-shrink material. To remove any wrinkles that might be visible you will need to
purchase, or borrow from a fellow modeler, a heat iron. If you need to purchase one, the Global Heat Sealing Iron # 360900
is recommended.
Follow this simple procedure to remove the wrinkles:
❑Plug in and turn on the sealing iron to the medium-high temperature setting. Allow the sealing iron to heat up for approximately
5 - 7 minutes.
❑After the sealing iron has reached temperature, lightly apply the sealing iron to the wrinkled section of the covering. Move the
sealing iron slowly over the wrinkled section until the covering tightens and the wrinkles disappear.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦You will notice that the color of the covering will darken when it is heated. When the covering cools back down,
it will return to its normal color.
☞If the color layer smears from any of the seams the temperature of the sealing iron is too hot. Turn the temperature dial down
and wait about 5 minutes for the sealing iron to adjust to the lower temperature. You can remove any excess color streaks using a
paper towel soaked with a small quantity of Acetone.
We do not suggest storing your airplane in an extremely hot environment (like the back of your car in direct sunlight)
for any length of time. The extreme heat could distort the molded plastic parts and/or cause the covering material to wrinkle and
possibly damage the fragile components of the radio system, ESC or flight battery.

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:
SECTION 6: WING ASSEMBLY
STEP 1: ALIGNING THE WING PANELS
❑Remove the aileron from each wing panel and set the ailerons aside
for now.
☞The ailerons are temporarily held in place for packing purposes,
using either thin plastic tabs in the hinge slots or extra hinges. These
pieces can be thrown away at this time. They won't be used for assembly.
❑Using a modeling knife, cut away and remove the excess covering
material that overlaps onto the root ribs of each wing panel, leaving
about 1/16" overlapped so it does not pull away.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦It's very important to the integrity of the wing center-section joint that you remove as much covering material
from the root ribs as possible. Do not omit this procedure or the wing center-section joint may fail during flight.
Continued On Next Page
☛☛
☛☛
☛

8
❑Use a ruler and a pencil to locate and draw a vertical centerline on
one side of the composite-reinforced wing joiner.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The wing joiner is cut in the shape of a shallow
"V." When you test-fit the wing joiner in the next procedure, make
sure that this "V" shape is toward the top of the wing panels. This
will ensure that the wing panels fit together with the proper amount
of dihedral.
❑When satisfied with the fit and alignment, pull the wing panels apart
and remove the wing joiner.
❑Apply a strip of masking tape to the top and bottom edges of the root
rib on each wing panel.
☞The masking tape will prevent excess epoxy from getting onto the
wing panels when you join them.
STEP 2: JOINING THE WING PANELS
❑Test-fit the wing joiner into each wing panel. It should slide easily
into each wing panel, up to the centerline you drew.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦When the wing joiner is installed, it should not fit
tightly into the wing panels. It should actually be slightly loose. This
will ensure that when you glue the wing joiner into place epoxy can
get into the joints between the wing joiner and the joiner box. This
will ensure the strongest joint possible.
☞If the wing joiner does not fit properly, use 220 grit sandpaper
with a sanding block to lightly sand the wing joiner, until you are satisfied
with the fit.
❑Carefully slide both wing panels together with the wing joiner
temporarily installed (without using glue).
❑While holding the two wing panels together firmly, make sure that
both wing panels are lined up at both the leading edges and the trailing
edges, then look carefully at the center-section joint: the wing panels
should fit together tightly with few or no gaps in the joint.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦If the wing panels do not fit together properly, remove the wing joiner and use 220 grit sandpaper with a
sanding block to lightly sand the edges and tips of the wing joiner, until you are satisfied with the fit. Remember, when the wing
panels are pushed together, there should be few or no gaps in the center-section joint.
Continued On Next Page
☛☛
☛☛
☛
❑Mix a generous amount of 5 minute epoxy. Working with only one wing panel for now, apply a thin layer of epoxy inside the wing joiner
box and to only half of the wing joiner. Make sure to cover the top and bottom, as well as the sides, and use enough epoxy to fill any gaps.

9
❑Slide the wing joiner into the wing panel until it bottoms out. Quickly remove any excess epoxy, using a paper towel and rubbing
alcohol, and allow the epoxy to set up before proceeding.
❑After the epoxy has set up, test-fit both wing panels together again to double-check that they still fit together properly. Check the
leading and trailing edges, too. It's important that they be even with each other.
❑Mix a generous amount of 5 minute epoxy and apply a thin layer to the exposed half of the wing joiner, the inside of the wing
joiner box in the second wing panel, and the entire surface of BOTH root ribs. Make sure to use enough epoxy to fill any gaps.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦It is of the utmost importance to the integrity of the wing center-section joint that you apply a generous amount
of epoxy to both root ribs and the wing joiner. Not using enough epoxy can result in wing failure during flight.
❑Slide the two wing panels together and realign them. Quickly wipe away any excess epoxy, using a paper towel and rubbing
alcohol, and use pieces of masking tape to hold the two wing panels aligned until the epoxy fully cures.
STEP 3: CHECKING THE WING CENTER-SECTION JOINT
❑Once the epoxy has fully cured, remove the masking tape and double-check the center-section joint. If any gaps are present,
mix a small quantity of 5 minute epoxy and carefully fill any remaining gaps.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Do not omit this procedure. The wing panels should fit together tightly, but it's possible to have some small gaps
that appear after the epoxy has cured. To make the wing center-section joint as strong as possible, it's important to fill any gaps,
using 5 minute epoxy.

SECTION 7: STABILIZER INSTALLATION
STEP 1: INSTALLING THE WING
❑Carefully apply a couple of drops of thin C/A into the two threaded
wing hold-down holes in the fuselage.
✦✦
✦✦
✦WARNING✦✦
✦✦
✦Allow the C/A to dry completely before proceeding
or you may inadvertently glue the wing hold-down screws into the
fuselage.
The C/A will harden the threads in the plywood, preventing them from
stripping out over time.
Continued On Next Page
☛☛
☛☛
☛

10
❑After the C/A has fully cured, set the wing into the wing saddle and
secure it into place, using the plastic wing-screw doubler and two
M3 x 20mm flange-head self-tapping screws.
☞Don't overtighten the screws or you'll crush the wing. They only
need to be tightened snug.
STEP 2: ALIGNING THE HORIZONTAL STABILIZER
❑Remove the elevator from the horizontal stabilizer and set it aside for now. Again, you can throw away the temporary pieces
that are in the hinge slots.
❑Using a ruler, builder's triangle and a pencil, carefully measure
and draw a vertical centerline across the top of the horizontal stabilizer.
❑Using a modeling knife, cut away and remove the covering material
from the top of the stabilizer mounting platform.

✦Remove as much covering material from the
mounting platform as possible, to ensure a strong glue joint.
❑Using a ruler and a pencil, carefully measure and draw on the
fuselage one centerline mark at the front of the stabilizer mounting
platform and one centerline mark at the back of the stabilizer
mounting platform.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦It may be necessary to trim the back edge of the plastic wing-screw doubler flush with the trailing edge of the
wing, using a pair of scissors.
☞The stabilizer has no top or bottom. Choose whichever side looks better to you for the top.

❑Set the stabilizer onto the fuselage and temporarily align it. When
aligned properly, the centerline you drew on top of the stabilizer should
be lined up with the two centerline marks you drew on the fuselage. The
trailing edge of the stabilizer should be even with the back edge of the
fuselage, too.
❑When satisfied with the alignment, hold only the trailing edge of the stabilizer in position, using a T-Pin. The front of the stabilizer
should be able to pivot slightly from side to side and the back should stay firmly in place.
❑Use a ruler to carefully measure the distance between the tips of
the stabilizer and the tips of the wing. Pivot the front of the stabilizer
right or left until both of these measurements are equal. When both
measurements are equal, the stabilizer is square to the wing.
❑When you are satisfied that the stabilizer is square to the wing, use a T-Pin to hold the front of the stabilizer firmly in place and aligned.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦When the stabilizer is square to the wing, it's possible that the centerline you drew on top of the stabilizer will not
be lined up with the centerline you drew on the fuselage at the front of the stabilizer mounting platform. That's okay.
❑When satisfied with the alignment, use a pencil to draw a line on each
side of the bottom of the stabilizer where it meets the fuselage sides.
❑With the stabilizer held firmly in place, look from the front of the
airplane at both the wing and the stabilizer. When aligned properly, the
stabilizer should be parallel to the wing.
☞If the stabilizer is not parallel to the wing, remove the stabilizer and use 220 grit sandpaper with a sanding block to sand down
the higher side of the stabilizer mounting platform, then reinstall the stabilizer and check the alignment once more. Repeat this
procedure until you are satisfied with the alignment.

STEP 3: MOUNTING THE HORIZONTAL STABILIZER
❑Remove the stabilizer from the fuselage.
❑Using a modeling knife, carefully cut away and remove the covering
material from between the lines you drew on the bottom of the stabilizer.
✦✦
✦✦
✦WARNING✦✦
✦✦
✦When cutting through the covering to remove it, cut with only enough pressure to cut through only the covering
itself. Cutting down into the balsa structure could weaken the stabilizer and cause it to fail during flight.
❑Mix and apply a generous amount of 5 minute epoxy to the gluing surfaces of the stabilizer and to the top of the stabilizer
mounting platform.
❑Set the stabilizer back into place and realign it, double-checking all of your measurements once more before the epoxy sets up.
Quickly remove the excess epoxy and use T-Pins to hold the stabilizer in place, until the epoxy has fully cured.
STEP 4: ALIGNING AND MOUNTING THE VERTICAL STABILIZER
❑Remove the rudder from the vertical stabilizer and set it aside for now. Again, you can throw away the temporary pieces in the
hinge slots.
❑Test-fit the vertical stabilizer to the top of the horizontal stabilizer
and fuselage, making sure that the mounting tab in the vertical stabilizer
fits into the mounting slot in the horizontal stabilizer. When aligned
properly, the trailing edge of the vertical stabilizer should be centered
over the centerline you drew previously on top of the horizontal stabilizer,
and the front of the vertical stabilizer should be centered between
the fuselage sides. The trailing edge of the vertical stabilizer should be
even with the trailing edge of the horizontal stabilizer, too.
❑When satisfied with the alignment, hold the vertical stabilizer in place, using a couple of T-Pins.
❑Using a pencil, draw an outline of the base of the vertical stabilizer onto the top of the horizontal stabilizer and the fuselage.
❑Remove the vertical stabilizer and use a modeling knife to carefully cut away and remove the covering material from inside the
outline you drew. Cut away and remove the covering material from the base of the vertical stabilizer, too.
❑Carefully glue the vertical stabilizer into place, using a generous
amount of 5 minute epoxy. Remove any excess epoxy, using a paper
towel and rubbing alcohol, and hold the vertical stabilizer firmly in place
and aligned, until the epoxy sets up.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦While the epoxy is drying, use a builder's triangle to
ensure that the vertical stabilizer is perpendicular to the horizontal
stabilizer.

SECTION 8: HINGING THE CONTROL SURFACES
STEP 1: HINGING THE AILERONS
✦✦
✦✦
✦Important Information About the C/A Style Hinges Included with Your Super Impress II EP ARF✦✦
✦✦
✦
The Super Impress II EP ARF uses C/A style hinges to hinge the control surfaces. These hinges are designed to be glued into
place, using thin C/A. Do not glue these hinges into place using any other type of glue, such as thick C/A or epoxy. Use of any
adhesive other than thin C/A could result in failure of the hinges during flight.
❑Push two T-Pins through the center of three C/A style aileron
hinges, as shown.
❑Working with one aileron for now, slide one hinge into each hinge
slot in the aileron, making sure that you push each hinge in up to the
T-Pins. Don't glue the hinges into place yet, though.
❑Push the aileron and its hinges into the hinge slots in the trailing edge of the wing, making sure that the torque rod wire is firmly
seated within the precut slot in the aileron. The aileron should be pushed firmly up against the trailing edge, so that there is a
minimal hinge gap (no more than 1/32" wide), and the end of the aileron should be even with the wing tip.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦You may need to cut the slot in the aileron for the torque rod wire deeper, so that the aileron can be pushed
forward enough to result in no more than a 1/32" wide hinge gap.
❑When satisfied with the fit, remove the aileron from the wing, but leave the hinges in the aileron.
Continued On Next Page
☛☛
☛☛
☛
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The T-Pins will keep the hinges centered while you are hinging the aileron.

14
❑Slide the waxed paper between the torque rod wire and the trailing
edge of the wing.
☞The waxed paper will prevent epoxy from gluing the torque rod wire
to the trailing edge of the wing.
❑Using 220 grit sandpaper, lightly sand the end of the torque rod wire to roughen the surface, then mix a small quantity of 5 minute
epoxy and apply a thin layer to the end of the torque rod wire and into the predrilled hole and the precut slot in the leading edge of
the aileron.
❑Push the aileron and its hinges into the hinge slots in the trailing edge of the wing and align the aileron as done previously.
❑Remove the T-pins from the hinges, and while holding the aileron
tight against the wing, pivot the aileron down about 45º and apply 5-6
drops of thin C/A to the exposed area of each hinge. Turn the wing
over and repeat for the other side of the hinges.
☞Remove any C/A that may run down the hinge line, using C/A
Debonder.
PRO TIP
STEP 2: HINGING THE ELEVATOR
❑Hinge the elevator, using the same techniques that you used to hinge
the ailerons. The elevator is hinged using four hinges. When hinging
the elevator into place, make sure that the tips of the elevator are even
with the tips of the stabilizer and that there is no more than a 1/32" wide
hinge gap.
❑Allow the C/A and epoxy to dry for about 15 minutes, then pivot the aileron up and down several times to free up the hinges.
After the C/A and epoxy have fully cured, gently grasp the aileron and wing and pull on the aileron like you are
trying to pull out the hinges. The hinges should hold securely. If one or more hinges feels loose, apply more C/A to the hinge(s)
and allow it to completely cure.
❑Repeat the previous procedures to hinge the second aileron to the wing, making sure to check the integrity of the hinges
after the C/A and epoxy fully cure.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦After allowing the C/A to fully cure, gently pull on the elevator to check the integrity of the hinges.
❑Using a pair of scissors, cut out a 1-1/2 long x 1" wide piece of waxed paper.

STEP 3: INSTALLING THE TAIL WHEEL ASSEMBLY
❑Test-fit the tail wheel wire into the predrilled hole in the leading
edge of the rudder. When properly aligned, the tail wheel wire should
rest within the precut slot and the front edge of the tail wheel wire should
be flush with the leading edge of the rudder.
☞It may be necessary to cut the slot deeper to achieve a perfect fit.
It's important that the front edge of the tail wheel wire be flush with the
leading edge of the rudder, so that it does not interfere with the proper
hinging of the rudder.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦With the tail wheel wire in place, double-check that the tail wheel is lined up with the bottom of the rudder. This
will ensure that the tail wheel will track straight with the rudder.
❑When satisfied with the fit and alignment, remove the tail wheel wire and use 220 grit sandpaper to roughen only the gluing
surfaces of the tail wheel wire.
❑Glue the tail wheel wire into place, using a generous amount of 5 minute epoxy. Remove any excess epoxy, using a paper towel
and rubbing alcohol, and allow the epoxy to set up before proceeding.
STEP 4: HINGING THE RUDDER
❑Hinge the rudder, using the same techniques that you used to hinge
the elevator. The rudder is hinged using two hinges. When hinging the
rudder, make sure that the top of the rudder is even with the top of the
stabilizer and that there is no more than a 1/32" wide hinge gap.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦After allowing the C/A to fully cure, gently pull on
the rudder to check the integrity of the hinges.

the wheel, then thread a second M2.5 hex nut onto the machine
screw and carefully tighten the two hex nuts against each other.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The wheel should be able to spin freely with little to
no side-to-side play.
❑Slide one M2.5 flat washer onto the machine screw and up against
the hex nuts.
❑Carefully slide the machine screw into the precut slot in the side of
one molded plastic wheel pant, making sure that the flat washer is on
the inside of the wheel pant.
❑Slide the machine screw through the predrilled hole in the main

SECTION 10: MOTOR AND COWLING INSTALLATION
STEP 1: INSTALLING THE MOTOR - FOR DIRECT DRIVE AND INLINE GEAR BOX MOTORS
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦Your kit includes a motor mount box for both direct drive and gear drive motors. Make sure that you use the
correct one for your particular setup. The long motor mount box should be used for direct drive motors (like the Wattage Super
400 Cobalt) and motors that use an inline gear box (like the Wattage Cobalt 400 Inline Gear Box). The short motor mount box
should be used for motors that feature an offset gear box (like the Wattage 370 Power System with 3.67:1 Gear Box).
Mounting screws are provided for both types of motor installation. Before installing your motor, double-check that the screws
provided will work properly with your setup.
These instructions show the installation of both types of motor installation. Step 1 shows direct drive motor installation and step
1B shows offset gear box motor installation.
❑Test-fit the long plywood motor mount box onto the firewall. When
positioned properly, the tabs in the back of the motor mount box should
fit into the slots in the firewall and the motor mount box should be pushed
firmly into place.
❑When satisfied with the fit, glue the motor mount box to the firewall, using a generous amount of 5 minute epoxy. Remove any
excess epoxy, using a paper towel and rubbing alcohol, and hold the motor mount box firmly in place, until the epoxy sets up.

❑Using a generous amount of 5 minute epoxy, glue one piece of balsa
triangle stock to each side of the motor mount box.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The triangle stock should fit firmly between the motor
mount box and the firewall. The triangle stock adds a lot of strength to
the joint, so don't skip this procedure.

18
❑Slide the motor into position and line up the holes in the front of the
motor with the precut slot in the motor plate.
❑Secure the motor into place, using two M3 x 8mm flange-head
machine screws.
☞Tighten the machine screws firmly to hold the motor securely
into place.
❑Install your propeller adapter onto the motor. So that the cowling will
line up with the spinner backplate when it's installed later, the front of
the propeller adapter should be 3/4" in front of the motor plate.
STEP 1B: INSTALLING THE MOTOR - FOR OFFSET GEAR BOX MOTORS
❑Test-fit the short plywood motor mount box onto the firewall. When
positioned properly, the tabs in the back of the motor mount box should
fit into the slots in the firewall and the motor mount box should be pushed
firmly into place.
❑When satisfied with the fit, glue the motor mount box to the firewall, using a generous amount of 5 minute epoxy. Remove any
excess epoxy, using a paper towel and rubbing alcohol, and hold the motor mount box firmly in place, until the epoxy sets up.
❑Using a generous amount of 5 minute epoxy, glue one piece of balsa
triangle stock to each side of the motor mount box.
❑If your motor has a propeller adapter on it, remove it from the motor and set it aside.

❑Drip several drops of thin C/A into the three predrilled pilot holes in
the motor mount box and allow the C/A to fully cure.
☞The C/A will harden the surrounding plywood, making the pilot
holes stronger.
❑Secure the motor assembly to the motor mount box, using three
M2 x 12mm flange-head wood screws.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦The pilot holes are predrilled to fit the Wattage
370 Power System and other similar gear box-mounted power systems.
STEP 2: INSTALLING THE COWLING
❑Slide the cowling into place and align it. When aligned properly,
the front of the cowling should be centered around, and be about
1/16"-3/32" behind, the front of the gear box or propeller adapter.
❑When satisfied with the alignment, use pieces of masking tape to hold
the cowling securely in place.
✦✦
✦✦
✦IMPORTANT✦✦
✦✦
✦No matter which type of power system you've chosen to use, the cowling installation procedures will be the same.
❑With the cowling held firmly in place and aligned, drill four 1/16"
diameter pilot holes into the cowling and through the sides of the
fuselage. Position two holes on each side of the cowling, 1/8" in
front of the back edge of the cowling. The lower holes should be 1/2" up
from the bottom of the cowling and the upper holes should be 2-1/8"
up from the bottom of the cowling.
❑Remove the cowling from the fuselage and carefully apply a couple of drops of thin C/A into the four holes you just drilled into the
fuselage. Allow the C/A to fully cure, then secure the cowling to the fuselage, using four M2 x 8mm wood screws.
❑Install your propeller and spinner assembly to finish off the installation.
