INTRODUCTION
The Reactor Bipe 3D EP is an evolution of our successful
Reactor series and was designed with both the 3D pilot and
sport flier in mind. Sport pilots will enjoy a stable airplane
with no bad tendencies that builds confidence and skill.
3D performance pilots will be surprised to find an airplane
capable of performing almost any maneuver with ease and
precision. Whatever your abilities are, you will enjoy an
accurate and nimble performer armed with a power package
that allows unlimited aerobatics. Best of all, it will fit into
practically any car and requires no disassembly – just grab
it and go!

PROTECTYOUR MODEL,YOURSELF
& OTHERS....FOLLOWTHESE
IMPORTANT SAFETY PRECAUTIONS
1.Your Reactor Bipe 3D EP should not be considered a toy,
but rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the Reactor Bipe, if not assembled and operated
correctly, couldpossiblycause injurytoyourselfor spectators
and damage to property.
2.Youmustassemblethemodelaccordingtotheinstructions.
Do not alter or modify the model, as doing so may result in an
unsafe or unflyable model.In a few cases the instructions may
differ slightly from the photos. In those instances the written
instructions should be considered as correct.
3.You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in first-class
condition, and a correctly sized motor and components
throughout the building process.
5. You must correctly install all R/C and other components
so that the model operates correctly on the ground and in
the air.
6.You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.
7. If you are not an experienced pilot or have not flown
this type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your first flights. If you’re not a member of a club, your local
hobby shop has information about clubs in your area whose
membership includes experienced pilots.
8.While this kit has been flight tested to exceed normal use,
if the plane will be used for extremely high stress flying, such
as racing, or if a motor larger than one in the recommended
range is used, the modeler is responsible for taking steps to
reinforce the high stress points and/or substituting hardware
more suitable for the increased stress.
9.WARNING:The cowl,wheel pants,and fairingsincluded in
this kit are made of fiberglass, the fibers of which may cause
eye, skin and respiratory tract irritation. Never blow into a
part to remove fiberglass dust, as the dust will blow back into
your eyes. Always wear safety goggles, a particle mask and
rubber gloves when grinding, drilling and sanding fiberglass
parts.Vacuum the parts and the work area thoroughly after
working with fiberglass parts.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and flyability of your finished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.
Remember:Take your time and follow the instructions to
end up with a well-built model that is straight and true.
LITHIUM BATTERY HANDLING & USAGE
WARNING!! Read the entire instruction sheet included with
the battery. Failure to follow all instructions could cause
permanent damage to the battery and its surroundings, and
cause bodily harm!
• ONLY use a LiPo approved charger.
• NEVER charge in excess of 4.20V per cell.
• ONLY charge through the “charge” lead. NEVER charge
through the “discharge” lead.
• NEVER charge at currents greater than 1C.
• ALWAYS set charger’s output volts to match battery volts.
• ALWAYS charge in a fireproof location.
• NEVER trickle charge.
• NEVER allow battery temperature to exceed 150° F [65° C].
• NEVER disassemble or modify pack wiring in any way or
puncture cells.
• NEVER discharge below 2.5V per cell
• NEVER place on combustible materials or leave
unattended during charge or discharge.
• ALWAYS KEEP OUT OF REACH OF CHILDREN.
DECISIONSYOU MUST MAKE
This is a partial list of items required to finish the Reactor Bipe
3D EP that may require planning or decision making before
starting to build.Order numbers are provided in parentheses.
Radio Equipment
A 4-channel radio system with four micro servos and a micro
receiver are required for this plane.We highly recommend
thatyouuseFutaba®S3154DigitalMicroHigh-Torqueservos.
The S3114 is a suitable alternative to this but because of the
nature of this particular airplane, the S3154 will provide a
better “on-center” feel.

❏(2) 12" [300mm] servo extension (HCAM2711 for Futaba)
❏(1)Y-harness (FUTM4130 or FUTM4135 for digital)
Motor & Propeller Recommendations
The Reactor Bipe EP was tested extensively to find the best
“power package”that offers light weight, long flight time, and
aggressive thrust. Because of the nature of electric motors,
the correct propeller must be chosen to get the most out
of the recommended motor without damaging components.
The order numbers for these are provided below.
❏Great Planes RimFire™35-36-1200kV Brushless
Out-runner Motor (GPMG4620)
❏APC 11" x 7" TE Thin Electric Propeller (APCQ4128)

sport (draws 30 amps max.)
– OR –
❏APC 10" x 5" TE Thin Electric Propeller (APCQ4120)
sport (draws 25 amps max.)
Note: Motors from other manufacturers may work with the
Reactor Bipe EP.However, the included motor mount adapter is
designed to work specifically with the Great Planes motor listed.
ESC (electronic speed control)
A brushless ESC (electronic speed control) is required for this
plane. We recommend using the Great Planes Silver Series
35A Brushless ESC 5V/2A BEC (GPMM1830). Any other ESC
should be capable of delivering a minimum of 34A continuous.
Battery Pack & Accessories
The Reactor Bipe EP has been tested with 11.1V LiPo packs
rangingfrom1200mAhto2100mAh.Ordernumbersareprovided
for packs of this size.The lighter 1200mAh pack is suggested for
maximum aerobatic performance, while the larger 2100mAh is
suggested for best flight times. If you are planning to use the
25C 1200mAh battery pack, you cannot use the APC 11" x 7"
propeller.In this case the 10" x 7" propeller is recommended.
❏FlightPower EVO25 LiPo 1200mAh 11.1V 25C Discharge

Note: Please be aware of the type of battery pack that you
are choosing for this airplane.The battery pack must be able
to deliver 30 amps continuously. The ones listed above are
capable of doing this when they are in a “new condition”
state. Batteries should be checked periodically using an
inline “watt meter” for their ability to deliver this current. A
battery’s maximum continuous current rating can be found
by multiplying the capacity (mAh rating) by the “C” rating by
0.001. For example: 1200mAh x 25C x 0.001 = 30 amps
A LiPo-compatible charger is required for these batteries,
along with a cell balancer.We recommend:

IMPORTANT BUILDING NOTES
• When you see the term test fit in the instructions, it
means that you should first position the part on the assembly
without using any glue, and then slightly modify or custom
fi t the part as necessary for the best fit.
• Whenever the term glue is written you should rely upon
your experience to decide what type of glue to use. When
a specific type of adhesive works best for that step, the
instructions will make a recommendation.
• Whenever just epoxy is specified you may use either
30-minute (or 45-minute) epoxy or 6-minute epoxy. When
30-minute epoxy is specified it is highly recommended that
you use only 30-minute (or 45-minute) epoxy, because you
will need the working time and/or the additional strength.
• Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following steps
to get another view of the same parts.
• Should covering repairs be required, use Top Flite®
MonoKote®. MonoKote is packaged in six-foot rolls, but some
hobby shops also sell it by the foot. If only a small piece of
MonoKote is needed for a minor patch, perhaps a fellow
modeler would give you some. MonoKote is applied with a
model airplane covering iron, but in an emergency a regular
iron can be used. A roll of MonoKote includes full instructions
for application.Following are the colors used on this model and
order numbers for six foot rolls.
Jet White – TOPQ0204
Metallic Teal – TOPQ0409
Metallic Plum – TOPQ0403
Metallic Platinum – TOPQ0408
• The stabilizer and wing incidences and motor thrust
angles have been factory-built into this model. However,
some technically-minded modelers may wish to check these
measurements anyway.To view this information visit the web
site at www.greatplanes.com and click on “Technical Data.”
Due to manufacturing tolerances which will have little or no
effect on the way your model will fly, please expect slight
deviations between your model and the published values.

BEFOREYOU BEGIN
Before you begin assembling your model, inspect it for
wrinkled covering and areas where the covering may not be
tacked down adequately. Areas like the servo bay openings,
theradioaccesshole(bottomoffuselage),andtheslotsforthe
horizontal stabilizer should be tacked down before trimming
them with a knife.The covering should be tacked down to the
wood using just enough heat to soften the adhesive backing.
Low heat should be enough to accomplish this. More heat
may be required to begin to tighten the covering.
ASSEMBLETHE WINGS
Install the Ailerons
❏ 1. Locate the four flat aileron link horns. Check the size
of the hole using one of the adjustable clevises. If the hole
is too small, drill it out using a #38 drill bit. If this size bit is
not available to you, a hobby knife can be used to carefully
ream out the hole. Use 220-grit sandpaper to roughen up
both sides of each link horn.This will improve adhesion.
❏ 2. Remove the adjustable clevis from the link horn and
slide it into the slot at the TE of each of the four ailerons.
Position each link horn so that the hole is aligned with theTE
of each aileron as shown.Glue each link horn using seven to
eight drops of thin CA glue.
❏ 3.Push aT-pinthrough the center oftwelve CA hingesand
test fit each hinge in the hinge slots in the top and bottom
wing panels and ailerons. If the hinge is difficult to insert
or the covering interferes with insertion, use a sharp hobby
knife to carefully enlarge the slot or trim the covering. To
improve the adhesion of the hinge, we recommend trimming
the covering from the area just above and just below the slot
so that the hinge does not draw the covering into the slot.
❏ 4. Insert the CA hinges halfway into the slots in the wing
panels. Carefully slide each aileron onto the hinges. Align
each aileron so that the tip of the aileron is even with the
edge of the wingtip. Push the ailerons in tightly and then
remove the T-pins from the hinges.
7

8
❏ 5.Deflect each aileron up and down until the beveled edge
lies flat with the TE of the wing panel. This will ensure that
you will achieve full travel of each aileron without opening too
muchofagap.Whensatisfiedwiththe fitof eachaileron,apply
seven to eight drops of thin CA glue to the top and bottom
of each hinge. Allow the CA a few minutes to harden before
attempting to move the ailerons.Do not use CA activator.
Install the Aileron Servos & Pushrods
❏ 1.Using a sharp hobby knife, trim open the aileron servo
bay in each lower wing panel.
❏ 2. With the splines facing forward, temporarily insert a
servo into each servo bay. Using a 1/16" [1.6mm] drill bit,
drill holes for the servo mounting screws (provided with
your servos).Thread a servo screw into each hole and then
remove the screwsand pull out the servos.Apply twoto three
drops of thin CA glue into each of the holes you threaded
and allow the CA to dry thoroughly.
❏ 3. Reinstall the aileron servos and use the installation
string to pull the servo lead out through the wing rib. Install
the servo mounting screws.
❏ 4. Use your radio to center the servos. Locate the servo
arms that fit the splines of your servos.Test fit a double-sided
servo arm onto each aileron servo. Fit the arm so that the
two arms are aligned parallel to the hinge line. Cut off the
inboard arm.
8

❏ 5. Locate four adjustable clevises, four 2 x 4mm sheet
metal screws, and the two 2 x 90mm carbon fiber pushrods.
Using 220-grit sandpaper, lightly sand the last 3/4" [19.1mm]
of each side of each pushrod. Slide a clevis on each end
of the pushrods and loosely thread a 2 x 4mm sheet metal
screw into each clevis. Insert the screw on the side of the
clevis that has the recessed hole.The other side of the clevis
is thicker for the screw threads to engage in.
❏ 6. Cut a 3/8" [9.5mm] long slot in the lower wing ailerons
just behind the beveled edge of the aileron LE.The slot will
be cut between two closely spaced ribs directly ahead of
where you installed the aileron link horns.
❏ 7. Clean the studs of the control horns with denatured
alcohol and glue the horns in place with epoxy or thick CA.
❏ 8. Install each pushrod in the control horn so that the
clevis is in the outermost hole of the control horn. Install
the other side of the pushrod in the servo arm so that the
clevis is in the second outermost hole. This will require
you to temporarily remove and reinstall the servo arm, so
remember to reinstall the servo arm screw.
Install the LowerWings
❏ 1. Trim the covering from the opening (and reseal along
the edges with a covering iron), just behind the battery
access hatch on the bottom of the fuselage.This is where
the receiver will be installed later.
❏ 2. Locate the front and rear wing joiners. Test fit each
one inside of the fuselage.You should not need to force the
joiner into position. If a joiner is too tight, you may lightly
sand the flat face and the upper or lower carbon edge of the
joiner until it will slide into place.Use only 220-grit sandpaper
for this.
9

10
❏ 3. Test fit the two lower wings to the joiners. Check to
see that each wing will slide all the way into its respective
fuselage pocket.
❏ 4. Using 30-minute epoxy, apply a thin film of epoxy to
the joiners and to the wing root ribs. Slide the lower wings
onto the wing joiner rods until the root ribs sit flat against
the fuselage sides. Masking tape may be used to hold each
wingtightlyagainstthefuselage.Clean up anyepoxy residue
using denatured alcohol.
Install the UpperWing
❏ 1. Locate the 5 x 120mm carbon strut tube. Use 220-
grit sandpaper to roughen up the top 1/2" [12.7mm] and
the bottom 1-1/2" [38mm] of the carbon strut tube. Without
applying any glue, slide the tube through the hole in the top
of the fuselage at a 55° angle. (To make it easier to achieve
the 55° angle, see the cabane strut installation template on
page 27). Push the rod in so that the top of the tube is 1-1/2"
[38mm] from the top of the fuselage.You will slide this up into
the top wing and epoxy it in place later.
❏ 2.Slide the small 2 x 10mm carbon rod through the small
hole in the top of the fuselage just ahead of where you fitted
the carbon strut tube. Position it so that approximately 3/16"
[4.8mm] of the rod is sticking out of the fuselage.Use thin CA
to glue this in place.
❏ 3.Test fit the cabane strut fairing to the fuselage, noting
that the bottom of the fairing is identified with an alignment
slot.Alignthefairingbyholdingitontothefuselageandsliding

11
it fore and aft until the fairing is approximately centered.With
a felt-tip pen, trace the outline of the fairing on the fuselage.
❏ 4. Use a hobby knife to trim the covering so that you are
trimming about 1/8" [3.2mm] inside of the line you drew. Re-
tack the covering using a sealing iron.Use denatured alcohol
to wipe away the lines.
❏ 5. Use 220-grit sandpaper to roughen up the bottom
gluing surface of the strut fairing. Using thick CA or epoxy,
glue the fairing and press it to the fuselage. Make sure that
the carbon strut tube is approximately centered in the hole
in the fairing.
❏ 6. Locate the two interplane struts and identify the top
front tab of each strut. Each strut is marked with the letters
“TF” to help you.Another way to identify the top of the strut
is to look for the small lightening hole behind the covering.
❏ 7. Use an interplane strut to help you locate the slots in
the top of the lower wings where the strut tabs will install.
The slots are located at the third rib in from the wingtip OR
about half-way in on each wing.You will be cutting between
two closely spaced ribs.The LE of the forward slot is 1-5/8"
[41.3mm] from the LE of the wing.The LE of the rear slot is
3-7/8" [98.4mm] from the LE of the wing. Each slot must be
cut 5/8" [15.9mm] long.If you have not already done so, use
a covering iron set to low to tack down the covering before
you trim.Trim the slots as shown.
❏ 8. Use an interplane strut to help you locate the slots in
the bottom of the top wing where the strut tabs will install.
These slots are located at the third rib in from the wingtip.
The LE of the forward slot is 1-5/8" [41.3mm] from the LE of
the wing.The LE of the rear slot is 3-7/8" [98.4mm] from the
LE of the wing. Each slot must be cut 5/8" [15.9mm] long.
Trim the slots as shown.
❏ 9. Test fit the interplane struts to the bottom wing. Make
sure that the tab marked “TF” is pointing up.Slide each strut
forward until it stops.

12
❏ 10.Test fit the top wing by sliding it onto the corresponding
strut tabs.Press the wing down and slide it back until it stops.
The LE of all the strut tabs must butt up against the back
edge of the wing spars.
❏ 11. Turn the model over and push the carbon strut tube
up into the wing.The strut tube is properly positioned when
the bottom of the tube sits no more than 1/8" [3.2mm] above
flush from the plywood support plate. This is not a critical
dimension. It is only a guideline so that you know that the
strut tube will be firmly anchored in the wing cavity.
❏ 12.When you are satisfied with the fit of the wing, remove
the upper wing and the interplane struts. Slide the carbon
rod back into the fuselage until it sits flush with the top of the
strut fairing.
Please Note: You should familiarize yourself with the next
few steps before you begin work.You will need to mix up
a batch of 30-minute epoxy and steps 13 through 18 must
be accomplished before the epoxy cures.
❏ 13. Apply 30-minute epoxy to the interplane strut tabs.
A thin film should be applied to both sides of the top and
bottom tabs.
❏ 14. Install the interplane struts onto the lower wings like
you did before.
❏ 15. On the upper wing, fill the strut tube cavity with
30-minute epoxy.
❏ 16.Turn the airplane over and install the airplane onto the
top wing.
❏ 17.Slidethecarbon strut tubeupinto thetopwing,making
sure that it sits no more than 1/8" [3.2mm] above flush from

13
the plywood support plate. Apply a generous bead of epoxy
to the carbon tube and plywood support plate.
❏ 18. Slide the two wing alignment jigs onto the wings
as shown. Do not force the jigs to slide closer than 1/2"
[12.7mm] from the interplane struts. Check the alignment of
the top wing by viewing from the top down – match the LEs
of the top and bottom wings.
❏ 19. Set the plane aside and allow the epoxy to cure.
BUILDTHE FUSELAGE
Install the Horizontal &VerticalTail
❏ 1. Trim the covering from the opening in the fuselage
where the horizontal stabilizer will install. Re-tack the
covering using a sealing iron.
❏ 2. Locate the “U” shaped elevator joiner wire and the
two elevator halves. Using 220-grit sandpaper, roughen up
the arms of the joiner wire.
❏ 3. Lay the elevator assembly on a flat work surface and
check to see that it lies flat. If not, remove the elevator joiner
wire and bend it a small amount. Reinstall the joiner wire and
check it again.Caution:Do not attempt to bend the joiner wire
while it is installed in the elevator halves.This can damage the
wood and cause the elevator to come apart in flight.
❏ 4. Insert the elevator joiner wire into the stab slot and
position it at the rear of the slot.
❏ 5.Withtheairplaneonalevelsurface,test fitthe horizontal
stab to the fuselage and position it so that it is as far forward

14
in the slot as it will go. Center the stab from left to right and
square it in the fuselage by measuring the distance from
each lower wingtip to the tips of the stab. Stand several feet
behind the model and check to see if the stab is parallel
with the lower wing. If it is not level, use a small weight to
level it. Lightly sanding the stab slot in the fuselage is also
acceptable, but be careful not to remove too much material.
Remove the stab.
❏ 6. Use thin CA to glue the horizontal stabilizer to the
fuselage. Run two generous beads of thin CA into the left
and right stab to fuse joints.Do this on the top and bottom of
the stab.Let the glue dry and check the stab for a strong and
secure bond.You may use CA debonder applied to a paper
towel to clean up any excess CA on the covering.
❏ 7. As you did with the ailerons, push a T-pin through the
center of 6 hinges and fit them to the horizontal stabilizer.
Carefully slide each elevator onto the stab and the elevator
joiner wire. Position the hinges so that they are equally
spaced. Bend the elevator up and down several times and
check for free travel.
❏ 8.When you are satisfied, use thin CA to glue the hinges and
the joiner wire.Be sure to wick at least five to six drops of CA into
the joiner wire.Allow this time to harden without CA accelerator.
❏ 9.Fittheverticalfinintothefuselage.Usingastraightedge
or the LE of the rudder, make sure that the TE of the vertical
fin is flush with theTE of the fuselage.When you are satisfied
with the fit, glue the fin to the fuselage.
❏ 10. Prepare and insert one hinge into the TE of the tail
skid. Do not glue the hinge yet. Apply medium CA to the
10mm washer and insert it into the slot at the bottom of the
tail skid.
❏ 11.Fit the tail skid to the bottom of the fuselage.Align the
skid with theTE of the fuselage as you did with the fin above.
Use a straightedge or a builder’s triangle to make sure that
the skid is vertical, and glue it to the fuselage.

15
❏ 12. Join the rudder to the fin using four CA hinges.
Install theTail Servos & Pushrods
❏ 1. Locate two control horns and two horn retainers. Fit
one horn to the bottom of the left elevator. Turn the model
over and install a horn retainer onto the stud of the control
horn. Apply one drop of medium CA to each side of the stud.
You may trim off the tip of the stud after the glue has cured.
❏ 2. Install the other horn on the right side of the rudder.
❏ 3. Trim the covering from the lower servo bay on the
right side of the fuselage.This is where the rudder servo will
be installed. Re-tack the covering using a sealing iron.
❏ 4. Trim the covering from the upper servo bay on the
left side of the fuselage for the elevator servo. Re-tack the
covering using a sealing iron.
❏ 5. Connect a 12" [305mm] servo extension to each of
the tail servos. Use one drop of medium CA or heat-shrink
tubing to secure the servo extension to the servo lead.

16
❏ 6.Feed the servo leads through the fuselage and into the
radio compartment. Position the servos so that the splines
face forward and drill 1/16" [1.6mm] holes using the servo
tabs as your guide.Thread a servo screw into each hole and
then remove the screws and pull out the servos. Apply two
to three drops of thin CA glue into each of the holes you
threaded and allow the CA to dry thoroughly.
❏ 7. Reinstall the tail servos and secure them with servo
mounting screws.
❏ 8. Use your radio to center the servos. Locate the servo
arms that fit the splines of your servos.Test fit a servo arm onto
each tail servo. Choose the arm that aligns closest to vertical.
❏ 9. Prepare the 2 x 155mm rudder pushrod and the
2 x 130mm elevator pushrod the same way you prepared the
aileron pushrods. Partially thread the 2 x 4mm sheet metal
screws into the clevises.
❏ 10. Install the 2 x 155mm rudder pushrod in the second
hole in from the tip of the rudder horn.Install the other clevis
in the outermost hole of the servo arm.
❏ 11.Install the 2 x 130mm elevatorpushrod in theoutermost
holeoftheelevatorhorn.Installtheotherclevisin thesecond
hole in from the tip of the servo arm.
Adjust the Pushrods & Link the Ailerons
❏ 1. Use your radio to help you adjust the length of each
pushrod.You should adjust your elevator, rudder, and both
aileron pushrods at this time. Use a straightedge to help
you center each control surface.You may use the wing jigs
to check the ailerons after you have made an adjustment.

17
For example: Turn on the radio, adjust the aileron pushrod,
check the position with the wing jig, readjust, and so on.
❏ 2.Tighten the 2 x 4mm sheet metal screws when you are
satisfied with the pushrod alignments.
❏ 3.Locate the two 2 x 160mm aileron link rods and install
one adjustable clevis to only one side of each rod. Position
the clevises as shown and secure them using 2 x 4mm sheet
metal screws. Use two drops of thin CA to glue the clevises
to the rods.
❏ 4. Install one of the aileron link rods to the lower aileron
of the left wing.Install it from the outboard side of the wing
so that the screw head is facing the front of the airplane.You
will make your adjustments to the opposite clevis.
❏ 5. Install an adjustable clevis to the top left aileron from
the outboard side. Insert the aileron link rod into this clevis
and adjust the rod length so that both ailerons are at “zero
throw” and are parallel to one another.You may use a wing
jig to help you check the alignment after the top and bottom
ailerons are linked.
❏ 6.Whenyouare satisfiedwiththeupperaileronalignment,
secure the clevis on the top left aileron with a 2 x 4mm
sheet metal screw.
❏ 7.Install the other aileron link rod to the upper aileron of
the right wing.Install it from the outboard side of the wing so
that the screw head is facing the front of the airplane.
❏ 8.Install an adjustable clevis to the bottom right aileron of
the right wing and insert the aileron link rod into the clevis.
Make the necessary adjustments and then secure the clevis
with a 2 x 4mm sheet metal screw.

FINISHTHE MODEL
Install the Landing Gear
❏ 1. Locate two axles, two 1.5" [40mm] foam wheels, four
2 x 8mm machine screws, and four 2mm washers.Note: Four
2 x 8mm washer head screws may be supplied in place of the
machine screws and washers.These will require no washers.
❏ 2. Apply light machine oil to the axle shaft and fit the
wheel. Apply threadlocking compound to one 2 x 8mm
machine screw. Install the screw with one 2mm washer on
the axle as shown.
❏ 3.Applythreadlockingcompoundtoone2 x8mmmachine
screw. Install the screw with one 2mm washer through the
landing gear leg as shown.
❏ 4. Put the axle and wheel assembly inside one wheel
pant. Thread it onto the 2 x 8mm axle screw and tighten
this down using the included wrench. As you are tightening,
position the wheel pant so that it keys into the landing gear
leg. Make sure that the wheel pants are installed so that the
swept edge of the landing gear leg is facing aft.
❏ 5. Locate two 3 x 15mm machine screws and two 3mm
washers. Apply threadlocking compound to the threads of
the screws and install the landing gear leg on the fuselage.
Install the ESC & Motor
❏ 1. Route the ESC through the radio compartment access
hole that you cut earlier. Pull the three motor leads through
the hole in the firewall using a curved-tip hemostat or long
nose pliers. Use one or more twist ties to bundle the motor
leads together to make it easier.

19
❏ 2. Apply threadlocking compound to the prop adapter
screws and tighten the prop adapter onto the motor.Remove
the“X” mount that was included with the motor and retain the
four 3 x 8mm countersunk screws.Tighten all motor screws.
❏ 3.Temporarily install the supplied wooden“X”mount using
the countersunk screws.Tighten the screws until the head is
1mm above the surface of the wooden “X” mount. Remove
the screws and the motor and harden the holes in the mount
with thin CA.
❏ 4. Apply threadlocking compound to the screw threads
and reinstall the “X” mount with the screws.
❏ 5. Apply threadlocking compound to four 3 x 10mm
machine screws and use four 3mm washers to attach the
motor to the motor mounting box.
❏ 6. Connect the motor leads to the ESC. Any motor wire
can be connected to any ESC wire at this point.
Install the Radio
❏ 1. Use the sketch above to help you locate the pre-drilled
antenna exit hole.Trim the covering from the antenna exit
hole only!You may skip this step and the next step if you are
using a 2.4GHz spread spectrum receiver.
❏ 2. Route your antenna lead through the hole and out of
the fuselage.Tape the end of the antenna to the side of the
tail skid.
❏ 3.Plug your servo leads into their corresponding channels
on the receiver.
❏ 4. Use double-sided servo tape to mount your radio
receiver to the back side of the forward wing spar.You may
apply 30-minute epoxy to the back side of the front wing spar
to help the double-sided tape stick better.
❏ 5. Make a battery strap out of the included 5" [127mm]
hook and loop material and route it as shown.

20
❏ 6.Attachthehook sideoftheincluded3" [76mm]adhesive
backed hook and loop material to the battery tray.
❏ 7.Without the propeller installed and your radio on, plug in
your battery and check to see which direction the motor
rotates.The motorshouldrotate counterclockwiseasviewed
from the front.If the motor rotates in the wrong direction, you
must unplug two motor leads and swap their position.
FINAL ASSEMBLY
❏ 1. Install the cowl.
❏ 2. Install the spinner backplate and then the propeller
onto the motor.
❏ 3. Install the battery hatch cover.
❏ 4. Use clear tape to attach the canopy as shown.
❏ 5.Taketime todoublecheckallofthe adjustable clevises
for security and each of your servo arm screws.Make sure
that all of the screws on the adjustable clevises are tight and
that none of the clevises slip on the pushrods when you pull
on them.After the initial“test flight”and when the controls are
trimmed, we recommend that you remove all of the pushrods
(noting their position) and carefully apply one drop of thin
CA to each adjustable clevis to permanently bond them to
their pushrods.This will rule out the possibility of a pushrod
slipping out of position.
❏ - 12 clevises tight
❏- 4 servo arm screws tight
Apply the Decals
1. Peel the decals from the die-cut decal sheet.
2.Be certain the model iscleanandfree from oily fingerprints
and dust. Prepare a dishpan or small bucket with a mixture
of liquid dish soap and warm water–about one teaspoon of
soap per gallon of water.Submerse the decal in the soap and
water and peel off the paper backing.Note: Even though the
decals have a “sticky-back” and are not the water transfer
type, submersing them in soap and water allows accurate
positioning and reduces air bubbles underneath.
3.Position decal on the model where desired.Holding the decal
down, use a paper towel to wipe most of the water away.
4.Use a piece of soft balsa or something similar to squeegee
remaining water from under the decal. Apply the rest of the
decals the same way.
