This section describes the items you will need to purchase for your new Tubby Cubby EP. These suggestions are not set
in stone, but they should provide you with a good starting point.
SECTION 1: OUR RECOMMENDATIONS
Here's what you'll need to finish the airplane:
P/N 443526 Cirrus MRX-4 FM Super-Micro Receiver
Hitec Single Conversion FM RX Crystal
P/N 444052 Cirrus CS-10 Super-Micro Servos (2)
P/N 128482 Wattage IC-5AMicro ESC
P/N 128526 Wattage 6 Cell 650Mah NiMH Flight Battery
P/N 130103 Wattage 6-8 Cell 1 amp AC/DC Peak Charger
IMPORTANT
The Tubby Cubby EP is a lightweight, slow-flying electric-powered model. When choosing accessories like servos,
ESC, and receiver, 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.
What Servos Do I Use?
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 0.19 ounces and have a torque rating of no less than 7.0 ounces per square inch.
What Receiver Do I Use?
The receiver should be as light as possible, preferably 1/2oz. or less. Most four-channel micro receivers will be a good
choice. If you plan on using the Hitec 555 Micro receiver or the HAS-3MB included with the Focus 3 radio system, 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.
What Electronic Speed Control Do I Use?
The ESC you choose should be capable of handling 5 amps continuous current. Again, lighter is better. Your ESC should
weigh no more than 1/2 ounce including the wiring and switch.
What Flight Battery Do I Use?
Forthebestflightperformance theflightbatteryusedshouldbea6cell 2/3AA270MahNiCDora6cell5/4AAA 650Mah
NiMH. NiMH batteries don't give quite as much power, but, more importantly, they are lighter and give significantly
more flight time. We do not suggest using 7 or 8 cell flight batteries because the airplane will be heavier and may not fly
quite as well. The trade-off is not worth the minor added performance.
IMPORTANT
ThepartnumberslistedfortheCirrusreceiver,CirrusservosandWattage ESC arecompatiblewithHitecandJR(receiver
is compatible with Hitec and Futaba only) radio control systems. These items are also available with connectors that are
compatible with Futaba and Airtronics radio control systems. (MRX-4 receiver is also available for Airtronics and JR
radio systems.)
When you purchase the Cirrus MRX-4 receiver, you must also purchase a Hitec brand crystal compatible with the
receiver. The crystal mustalsobe on the samefrequencyas your transmitter. Note thattheCirrus MRX-4 receiver uses
a single conversion FM Hitec crystal. Adual conversion crystal will not work with it.
Flight Battery Warning
Toensureextendedbatterylifeandthebest
performance from your flight battery, the
flightbatteryshouldbechargedatnomore
than 1 amp. Always allow the battery to
cool before recharging. Never charge the
flight battery when it's hot.

SECTION 4: METRIC CONVERSION CHART
IMPORTANT
The soldering iron and solder listed above are optional. Depending on the ESC and flight battery you have chosen to use,
theymay not have plugs thatare compatible with the plug that comespreinstalled on the motor. If thisis the case you will
need to solder a compatible plug onto the motor or, better yet, solder the ESC leads directly to the motor.
WARNING
The Tubby Cubby EPis constructed of EPS and Closed Cell Foam. It is very important that you use no solvents,
Cyanoacrylate (C/A) glue, or paint that can damage foam. If any of these chemicals comes in contact with the
foam parts, the parts will be destroyed and will not be covered under warranty. Use only epoxy where glue is
required. If you decide to add painted details to the airplane, use acrylic-based paints and always test the paint
on a scrap piece first.
WARNING
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 cause the foam to melt and possibly damage the fragile
components of the radio system, ESC or batteries.

☞Look carefully at the ends of the reinforcement board.
Youwillnoticeoneendis cut straight and oneendiscutatan
angle. The angled end goes toward the front of the fuselage.
❑Carefully adhere the reinforcement board to the fuselage.
To align it properly, the angled end should be lined up with
the back edge of the motor plate and the top edge should be
even with the top of the fuselage.
❑Remove one piece of reinforcement board from its protective backing.
Step 2: Installing the Wooden Dowels
❑Repeat the procedures above to apply the second piece of reinforcement board to the other side of the fuselage.
❑Usinga 1/8"drill bit,drill four holes through the fuselage
sides using the die-cut holes in the reinforcement board as a
guide.
☞To prevent tearing up the foam, don't drill the holes
using an electric drill. It is better to use your fingers to
slowly twist the drill bit.
❑Test-fit the two wooden dowels into the fuselage. The
100mm long dowel is installed through the forward holes
and the 70mm long dowel is installed through the rear
holes. Adjust both dowels so that they are centered in the
fuselage.
❑Remove both dowels and mix a small quantity of 5 minute epoxy. Apply a thin layer of epoxy inside each of the
four holes.
❑Slide the dowels back into place and realign them. Remove any excess epoxy using a paper towel and rubbing
alcohol, and set the fuselage aside until the epoxy sets up.

❑Using220gritsandpaperwitha sanding block,lightlysandtheedgesofthestabilizerand elevatoreven with each other.
Step 2: Mounting the Horizontal Stabilizer Assembly
❑Using a ruler and a pencil, draw a centerline across
the top of the horizontal stabilizer.
☞The line should be perpendicular to the hinge line as
shown.
❑Using a ruler and a pencil, draw a centerline mark on
the bottom, back edge of the stabilizer as shown.
❑Hinge the elevator to the horizontal stabilizer using the
clear decal. Apply the decal to the top of the parts, making
sure there is a 1/16" gap between them to allow for the up
and down movement of the elevator.
☞Use the guide marks on the ends of the decal to help you
set the correct hinge gap.
❑Set the stabilizer assembly on top of the fuselage, making
sure the top of the stabilizer is facing up toward you.
❑To align the stabilizer properly, the trailing edge of the
stabilizer(nottheelevator)shouldbeevenwiththebackedge
of the fuselage and the centerline you drew on top of the
stabilizer should be centered over the middle of the fuselage.
☞Use the mark you drew on the bottom of the stabilizer to
help you align it at the back of the fuselage.

11
Visit our website at http://watt-age.globalhobby.com for information on other Wattage products
❑When satisfied with the alignment, hold the stabilizer in
place and use a pencil to draw two lines on the bottom of the
stabilizer(oneoneachside)whereitmeetsthefuselagesides.
☞Be careful that the stabilizer assembly does not move
when you draw the lines.
❑Mix a small quantity of 5 minute epoxy and apply a thin layer to only the bottom of the stabilizer between the two
lines you drew.
❑Set the stabilizer back into place and realign it. Remove any excess epoxy using a paper towel and rubbing alcohol,
and hold the stabilizer firmly in place until the epoxy sets up.
Step 3: Hinging the Rudder
❑Carefully remove the die-cut vertical stabilizer and rudder from the foam sheet.
❑Using 220 grit sandpaper with a sanding block, carefully sand the edges of the stabilizer and rudder smooth and
straight.
❑Using a ruler and a modeling knife, carefully cut out the clear rudder hinge from the decal sheet.
❑Using 220 grit sandpaper with a sanding block, lightly sand the edges of the stabilizer and rudder even with each other.
❑Hingetheruddertotheverticalstabilizerusingtheclear
decal, making sure there is a 1/16" gap between them to
allow for movement of the rudder.
☞Use the guide marks on the ends of the decal to help you
set the proper hinge gap.
Step 4: Mounting the Vertical Stabilizer Assembly
❑Test-fit the vertical stabilizer to the top of the horizontal
stabilizer.
❑To align the stabilizer properly, the base of the stabilizer
should be lined up over the centerline you drew on top of the
horizontal stabilizer and the trailing edge of the stabilizer
should be even with the trailing edge of the horizontal
stabilizer.

❑While holding the vertical stabilizer in place, use a
builder's triangle to check to ensure that it is aligned 90º to
the horizontal stabilizer.
❑When satisfied with the alignment, remove the vertical stabilizer. Mix a small quantity of 5 minute epoxy and apply
a thin layer to only the bottom edge of the vertical stabilizer.
❑Setthestabilizer back into placeandrealign it, double-checking thatitis 90º to the horizontalstabilizer. Remove any

☞Drawthemark in the centerofthemotor plate to makeit
easier to align the gear box assembly.
❑Carefully press the landing gear wire into the molded
groove in the back of the gear box assembly.
IMPORTANT
To make it easier to line up the gear box assembly properly in the next few procedures, we suggest using a ruler and a
pencil to draw a vertical centerline on the plywood motor plate.
❑Slidethemotorwiresintotheprecutholein the motor plateandoutthroughtheholeyoucutinthetopofthefuselage.
❑Push the gear box assembly up against the motor plate.
❑To align the gear box assembly properly, the gear box
should be centered from side to side on the motor plate and
the top of the gear box should be even with the mark you
drew (1/8" below the top of the motor plate.)
❑When satisfied with the alignment, use a pencil to mark
thelocationsofthethreemountingholesontothemotorplate.
❑Remove the gear box assembly and set it aside. Using a drill with a 1/16" drill bit, drill pilot holes through the motor
plate at each of the three marks you drew.

14 Need help or have any questions? Call us at 1-714-963-0329 or send us an email to [e-mail]
❑Set the gear box assembly back into place and realign it.
❑Install and tighten the three 3mm x 12mm wood screws to hold the gear box assembly securely to the fuselage.
☞Be careful not to overtighten the screws or you might strip the plywood motor plate.
Step 2: Installing the Main Gear Wheels
☞Double-check that the wheel spins without binding. If the wheel does bind, carefully pull the nylon wheel retainer
just far enough away from the wheel to prevent the binding.
❑Repeat the procedure above to install the second wheel and wheel retainer.
❑Slide one wheel onto one of the axles.
❑Using needle nose pliers, carefully squeeze one nylon
wheel retainer onto the axle to secure the wheel intoplace.
If you would like to use a more to-scale lightweight foam wheel, we recommend using the 2-1/4" Dave Brown Treaded
Lectra-LiteWheels P/N 218547. The axle hole in the wheels will have a larger diameter than the axles, but you can use
a piece of KNS aluminum or brass tubing as a bushing. Hold the wheels in place using either small wheel collars or by
simply bending the end of the bushings up at an angle.

❑Using a modeling knife, cut out the small molded circle
and the molded air-intake in the front of the cowling.
❑Using a pair of scissors, cut out the back edge of the
cowling to allow clearance for the landing gear wires.
☞Ifyoulook carefully ateachside of the cowlingyou will
notice scribe lines showing you where you need to cut out
for the landing gear wires.
Step 2: Installing the Cowling
❑Slide the cowling over the gear box assembly and onto the fuselage.
❑Thread one 3mm hex nut onto the propeller shaft and tighten it until it will not thread on any further.
❑Slide the propeller onto the propeller shaft, making sure
that the back of the propeller slides firmly over the hex nut.
☞The back of the propeller is molded to fit over the hex
nut.
❑Slide the 3mm flat washer into place, then install and
tighten the second 3mm hex nut using an adjustable wrench.
❑Carefully adjust the cowling so that it is centered around the end of the gear box and make sure the back edge of the
cowling overlaps (or is even with) the back edge of the plywood motor plate.
IMPORTANT
The top of the cowling will be pushed above the top of the fuselage by the plywood plate. This is normal. It is done to
make a space for hot air to exit the cowling so the motor and gear box do not overheat.

protective backing and stick the board to the side of the
fuselage. The back and top edges of the servo mounting
boardshouldbeevenwith the fuselage reinforcement board
as shown.
❑Repeat the procedure above to apply the second piece of servo mounting board to the other side of the fuselage.

❑Usingamodeling knife, cut away andremovethe foam from within thecutoutin each piece of servomountingboard.
❑Using a modeling knife, cut a 1/2" square hole in the top
of the fuselage, 3/4" in front of the rear wing hold-down
dowel.
☞The servo wires will come out through this hole for easy
access when connecting them to your receiver.
Step 2: Installing the Nylon Control Horns
❑Using the tip of your modeling knife, carefully remove the small die-cut pieces from the elevator and the rudder.
❑Push one control horn through each die-cut hole in the rudder and the elevator. The tip of the elevator control horn
should face the bottom of the elevator and the tip of the rudder control horn should face the opposite side of the rudder.
❑Making sure that the flat portion of the backplates face
away from the control surfaces, push the backplates over the
ends of the control horns until you hear them "click" firmly
into place.
Step 3: Installing the Elevator and Rudder Servos
❑Test-fit one servo into each side of the fuselage. If the
servosare toolargetofit, use a modeling knife to enlargethe
holes to accommodate the servos.
☞Both of the servos' output shafts should face toward the
front of the fuselage.
❑Install the rubber grommets and brass collets onto each of the servo mounting lugs.
❑Mount the servos using the servo mounting screws provided with your servos. To make it easier to install the screws,
use the tip of your modeling knife to make small pilot holes in the servo mounting board.

Step 4: Installing the Elevator and Rudder Pushrods
❑Plugtheelevatorandrudder servo leads into theirproperslotsinthe receiver. PlugtheESCleadintothereceiverand
plug the flight battery into the ESC . Turn on the radio system and center both of the servos using the elevator and rudder
trim levers on the transmitter.
❑Thread one nylon clevis onto each of the two 1.5mm x 400mm threaded pushrod wires. Thread the clevises on far
enough to leave room for adjustments later.
❑Working with one pushrod wire for now, carefully snap
the clevis into the elevator control horn.
❑Place a "single arm" servo horn onto the elevator servo (on the same side as the elevator control horn), making sure
that the servo horn is centered and points up toward the top of the fuselage. The arm should have at least two holes in it.
❑Using Magnum Z-Bend Pliers, make a Z-Bend in the pushrod wire at the mark you drew and use wire cutters to
remove the excess wire.
❑Removetheservo horn. Using a 1/16"drillbit, enlargethehole in the servoarmthat is 1/4" outfromthe center of the
servo horn.
❑With both the servo horn and the elevator centered, use a
pencil to draw a mark on the pushrod wire where it crosses
the hole that is 1/4" out from the center of the servo horn.
☞If you're using Cirrus CS-10 servos this will be the first
hole in the servo arm.
❑Attach the servo horn to the Z-Bend, then attach the
servo horn to the servo, making sure it's centered.
❑Installandtightentheservohornretainingscrew,provided
with your servo, to secure the servo horn into place.

❑Install the rudder pushrod wire using the same technique as with the elevator pushrod wire. The Z-Bend should be
installed into the hole that is 1/4" out from the center of the servo horn as well.
❑Double-check that the elevator and rudder are still centered. If they are out of adjustment, remove the clevises and
readjust them until you are satisfied with the alignment. Unplug and turn off your radio system.

Step 1: Trimming the Plastic Parts
❑Usingapairofscissors,carefullycutoutaroundthebase
of the plastic wing mount leaving about 3/16" of material
beyond the molded radius.
❑Test-fit the wing mount onto the fuselage. To align it properly, the front edge of the wing mount should be pushed up
against the back edge of the cowling and the wing mount should be centered over the fuselage. If the edges of the wing
mount hang past the fuselage sides, trim the edges using a pair of scissors so that they are even with the fuselage sides.
❑Whensatisfied with the fit,use 220 grit sandpaperwith a sandingblockto carefully sandthe edges of thewing mount
smooth and straight.

❑Usingapairof scissors,carefullycutouttheplasticwing
brace along the molded upper edges.
☞When cutting out the wing brace, make sure not to leave
any molded radius around the edges.
❑Using 220 grit sandpaper with a sanding block, sand the edges of the wing brace smooth and straight.
Step 2: Joining the Wing Panels
❑Remove the protective backing from only one side of
each strip of double-sided tape.
❑Carefully apply one stripof tapeto the top of eachsideof
the plastic wing mount as shown.
❑Use a pair of scissors to cut one 1/2" wide by 6-3/8" long strip out of each piece of double-sided tape.
IMPORTANT
Before applying any pieces of double-sided tape to either the plastic parts or the foam wing panels, it's important to clean
the area first using a paper towel and rubbing alcohol. This will remove any traces of oil on the parts and result in a
stronger bond. Before applying the tape make sure any traces of rubbing alcohol have completely dried from the surfaces
to be joined.
❑Using the remaining double-sided tape, apply the pieces
overtheentiresurfaceofthebottomoftheplasticwingbrace.
IMPORTANT
For maximum wing strength, it's important to cover the
entire surface of the wing brace with double-sided tape.
☞You should have leftover double-sided tape after these procedures. Save the extra because it will be used later.
