SECTION 1: OUR RECOMMENDATIONS

This section describes the items you will need to purchase for your new P-51 Reno Racer EP. These suggestions are not
set in stone, but they should provide you with a good starting point.

IMPORTANT

When choosing accessories for your P-51, such as servos, ESC, and receiver , it's very important to t ake 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 would be a good
choice. If you plan on using the Hitec 555 Micro receiver, 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 10-15 amps continuous current. Again, lighter is better. Your ESC
should weigh no more than 1 ounce including the wiring and switch.

Note: Although a 10 amp ESC may work with our recommended battery, motor and propeller, it is at the low end of the scale.

Since some customers may wish to experiment with other motors, batteries and propellers, chances are a 15 amp ESC will
then be necessary because of higher current draw; therefore, we recommend just starting with a higher-capacity ESC.

What Flight Battery Do I Use?

To get good flight performance you need to use the right type of flight battery. You need a flight battery that can
deliver enough voltage and be able to handle current draw up to approximately 10 amps. Through much testing on this
power system, we have found the 8 cell 800Mah 5/4AAA NiMH battery pack delivers the best performance in terms of
weight, power and duration. You certainly could use NiCD battery packs - they will give you more power, but they are
heavier and offer much less duration than NiMH batteries. Depending on how you fly the airplane, the trade-off between
higher weight and less duration may not be worth the extra power.

Note: At the time of this writing, NiMH batteries cannot withstand current draw about 10 - 12 amps. If you use our included 380

size motor and 5 x 2.5 propeller, current draw will not be a problem. However, if you experiment with larger propellers or
different motors, the current draw may be too much for NiMH batteries. If this is the case, you will need to use NiCD
batteries in your airplane. NiMH battery technology is evolving quickly, so in the future they may be compatible with
high-draw power systems.

WARNING

The P-51 Reno Racer EP is constructed of 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 on the foam parts 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.

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.

SECTION 6: MOTOR BREAK-IN

YOU'LL NEED THE FOLLOWING PARTS:

❑ (1) 380 Size Motor

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ Wire Cutters
❑ Paper Towels
❑ K&S 30 Watt Soldering Iron
❑ Solder

IMPORTANT

Before installing the motor into the fuselage it must first be broken in. This accomplishes two very important things:
breaking in the motor will maximize its performance, and, most importantly, you will be able to verify that the motor is
working properly before installing it into the airplane. It is strongly suggested that you not skip this important section.

To break in the motor, it is recommended that the motor be run for at least 10 minutes without a propeller at a voltage of
less than 5 volts - a 4 cell receiver battery pack works great for this. The low voltage will keep the motor from overheating
while the brushes and bushings seat. Please follow the procedures below for proper motor break-in.

❑ Emerald Performance Plus Motor Spray
❑ Trinity Motor Break In Drops
❑ Rubber Bands

Step 1: Installing the Motor Wires

❑ Solder two 6" long 14 gauge hi-temp silicon motor wires
(not included) to the positive and negative terminals on the
back of the motor.

Step 2: Breaking In the Motor

8

Need help or have any questions? Call us at 1-714-963-0329 or send us an email to [e-mail]

The terminal with the red dot next to it is the positive

☞

terminal.

❑ Set the motor between the handles of a pair of wire
cutters and secure the motor to the handles using several
rubber bands. This will keep the motor secure enough for the
break-in procedure.

❑ Before operating the motor, apply a couple of drops of Break In Drop s to the motor bushings. (One at the front and one
at the back of the motor.)

❑ Operate the motor using a fully charged 4 cell battery pack and allow the motor to run for about 8 - 10 minutes. After
8 - 10 minutes, remove the battery pack and spray Motor Spray into the motor (through the two holes in the side of the
motor) to clean the brushes. Apply more Break In Drops to the bushings and run the motor for another 3 - 5 minutes.

❑ After 3 - 5 minutes, remove the battery pack from the motor and spray the brushes clean with Motor Spray. Apply a
couple of drops of Break In Drops to the bushings and wipe the motor clean using a paper towel.

❑ Now that you've completed breaking in the motor, remove the motor and set it aside for installation later.

SECTION 7: FUSELAGE ASSEMBLY

YOU'LL NEED THE FOLLOWING PARTS:

❑ (1) Fuselage
❑ (1) 380 Size Motor
❑ (1) Motor Mounting Plate
❑ (2) 2mm x 4mm Machine Screws
❑ (1) Plywood Radio Tray

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ Kwik Bond Thick C/A
❑ Wilhold Silicon Sealant
❑ # 0 Phillips Head Screwdriver
❑ # 1 Phillips Head Screwdriver
❑ Excel Modeling Knife

Step 1: Installing the Motor

❑ (1) 3mm x 20mm x 45mm Plywood Plate
❑ (2) 3mm x 10mm x 20mm Plywood Plates
❑ (1) 3mm x 20mm x 60mm Plywood Plate
❑ (1) Nylon Battery Tie-Down Strap
❑ (2) 3mm x 10mm Wood Screws

❑ Electric or Hand Drill
❑ 1/8" Drill Bit
❑ Ruler
❑ Pencil
❑ 220 Grit Sandpaper w/Sanding Block

❑ Using a ruler and a pencil, outline the portion of the wing

saddle that needs to be removed for access to the inside of
the fuselage. For strength, there should be 3/8" of material
left between the fuselage sides, 3/4" in front of the back of
the wing saddle and 3/8" behind the front of the wing saddle
as shown.

Visit our website at http://watt-age.globalhobby.com for information on other Wattage products

9

❑ Using a modeling knife, carefully cut out the wing saddle
along the outline you drew.

Instead of trying to cut through the plastic in one pass,

☞

it's easier to make several shallow cuts. It also helps to use a
very sharp knife blade.

❑ Using a modeling knife, carefully cut away the molded
"button" flush from the front of the fuselage.

❑ Using a modeling knife, carefully cut open the air-intake
scoop below the motor mounting area.

❑ Hold the motor mounting plate against the front of
the fuselage, centering the outer edge of the plate with the
outer edge of the fuselage.

❑ While holding the motor mounting plate in place, use a pencil to mark the locations of the two mounting holes onto the
front of the fuselage.

❑ Using a modeling knife, carefully cut two 1/8" wide slots
from the center hole out beyond the two marks you drew.

We do not suggest drilling the two motor mounting holes.

☞

They are so close to the center hole that keeping them aligned
while drilling will be difficult.

10

Need help or have any questions? Call us at 1-714-963-0329 or send us an email to [e-mail]

Step 2: Installing the Plywood Radio Tray

❑ Mount the motor to the fuselage using the motor plate
and two 2mm x 4mm machine screws. Tighten the machine
screws firmly to hold the motor securely in place.

Because of the length of the nose, it's easiest to drop the

☞

motor into the front of the fuselage and hold it by the shaft
while installing the plate and screws.

❑ Using thick C/A, glue the two 3mm x 10mm x 20mm
plywood plates to one side of the 3mm x 20mm x 60mm
plywood plate, making sure to position the two plates as
shown. This assembly is referred to as the "mounting
plate."

The rear plate is even with the back edge of the larger

☞

plate (straight edge) and the front plate is 1/4" behind the
front of the larger plate (rounded edge).

❑ Using 220 grit sandpaper with a sanding block, sand the edges of the mounting plate smooth and even.

IMPORTANT

Before gluing the mounting plate to the radio tray in the next
procedure, it's important that the two small plates are glued to
the radio tray, not the larger plate.

❑ Using thick C/A, glue the mounting plate to one side of
the radio tray. The mounting plate should be centered down
the middle of the radio tray and the back edge of the mounting
plate should be 3/8" in front of the square servo cutout.

❑ Install the nylon battery tie-down strap through the two
precut holes in the front of the radio tray as shown.

Notice that the ends of the tie-down strap are toward the

☞

side opposite the mounting plate. This is important.

Visit our website at http://watt-age.globalhobby.com for information on other Wattage products

11

❑ Using a ruler and a pencil, measure and mark the locations
of the two wood screws used to hold the radio tray in place.
The screws are located on the centerline of the fuselage (the
mold seam), 1/4" in front of the back edge of the cockpit and
2" in front of the back edge of the cockpit.

❑ Using a 1/8" drill bit, drill a hole through the fuselage at each of the two locations you marked.

❑ Place the radio tray into the fuselage and position it as

shown. When aligned properly , the mounting plate should fit
into the molded cockpit recess and the rounded corners on
the front of the mounting plate should be pushed against the
front of the cockpit recess.

❑ When satisfied with the alignment, remove the radio tray and apply a bead of silicon to the bottom of the mounting plate.

Step 3: Installing the Plywood Wing Screw Plate

❑ Set the radio tray back into place and realign it.

❑ Install and tighten the two 3mm x 10mm wood screws to

secure the radio firmly to the fuselage.

It's not necessary to drill pilot holes in the mounting plate

☞

for the wood screws.

❑ Test-fit the 3mm x 20mm x 45mm plywood plate to the
underside of the wing saddle as shown. The plate should be
centered and even with the front of the cutout

12

Need help or have any questions? Call us at 1-714-963-0329 or send us an email to [e-mail]

❑ When satisfied with the fit, remove the plate and thoroughly sand the gluing surface on the underside of the wing
saddle to roughen the plastic. Do not omit this procedure or the adhesive will not stick to the plastic.

❑ Glue the plywood plate into place using a thick bead of silicon. Push the plate firmly against the wing saddle until
silicon begins to squeeze from the joint, and remove any excess using a paper towel.

IMPORTANT

When gluing anything to the molded plastic fuselage, we strongly suggest using only silicon or epoxy. Use of C/A is not
recommended. C/A dries brittle so it tends to break loose from the plastic under minimal stress. It is also very import ant

to roughen the plastic before gluing anything to it. This helps the adhesive stick much better.

SECTION 8: WING ASSEMBLY & MOUNTING

YOU'LL NEED THE FOLLOWING PARTS:

❑ (1) Left & Right Wing Panels
❑ (1) Center Section Reinforcement Board
❑ (1) Trailing Edge Reinforcement Board
❑ (1) Molded Plastic Radiator Scoop
❑ (1) 3mm x 20mm x 40mm Plywood Plate

YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:

❑ Kwik Bond 5 Minute Epoxy
❑ # 1 Phillips Head Screwdriver
❑ Excel Modeling Knife
❑ Scissors
❑ Electric or Hand Drill
❑ 5/64", 7/64", 1/8" and 5/16" Drill Bits
❑ Ruler

Step 1: Cutting Out the Ailerons

❑ (1) 30mm Fiberglass Dowel
❑ (1) 3mm x 18mm Wood Screw
❑ (2) Prebent Aileron Torque Rods
❑ (1) Aileron Reinforcement Board - 2 Parts

❑ Pencil
❑ 220 Grit Sandpaper w/Sanding Block
❑ Paper Towels
❑ Rubbing Alcohol
❑ NHP Epoxy Mixing Sticks
❑ NHP Epoxy Mixing Cups

❑ Carefully flex the aileron up and down several times to free up the hinge line.

❑ Repeat the previous procedures to cut out the aileron on the second wing panel.

Visit our website at http://watt-age.globalhobby.com for information on other Wattage products

❑ Turn one wing panel upside down, so the molded groove
is facing up toward you.

❑ Use a modeling knife and a ruler to carefully cut out the
inner and outer end of the aileron at each end of the groove.

Make the cuts perpendicular to the trailing edge of

☞

the wing.

13

Step 2: Joining the Wing Panels

❑ Test-fit the two wing panels together. They should fit
together with few or no gaps between the two, and the leading
and trailing edges should line up evenly.

If the wing panels don't fit together properly, carefully

☞

sand the root ends of each wing panel straight using 220 grit
sandpaper with a sanding block, being careful not to change
the dihedral angle.

IMPORTANT

Before gluing the wing panels together in the next procedure, it's important to know that the top of the wing should be
straight across (flat). You can easily achieve this by gluing the wing panels together upside down on your building table.

❑ Mix a generous amount of 5 minute epoxy and carefully apply a thin layer to the root ends of both wing panels.

WARNING

For maximum wing strength, make sure to cover the entire surface of each root end.

❑ Fit the wing panels back together and realign them.
Remove any excess epoxy that squeezes out of the joint
using a paper towel and rubbing alcohol, and hold the wing
