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.

Here's What We Used to Finish Our P-51 Reno Racer EP:
Note: To minimize current loss, we suggest
soldering the motor wires directly to the ESC.
We also suggest replacing the stock Tamiya
connector that is likely preinstalled on your
ESC and flight battery with a more efficient
Dean's Ultra-Plug battery connector.
P/N 131175Wattage 14 Gauge Hi-Temp Silicon Wire
3M 3/4" Wide Clear Plastic Tape - Available at Most Hardware Stores
IMPORTANT
The part numbers listed for the Hitec receiver, Cirrus servos and Wattage ESC are compatible with Hitec and JR (receiver
is compatible with Hitec only) radio control systems. These items are also available with connectors that are compatible
with Futaba and Airtronics radio control systems. (Micro 555 receiver is also available for Airtronics, Futaba and JR radio
systems.)
When you purchase the Hitec Micro 555 receiver, you must also purchase a Hitec brand crystal compatible with the
receiver. The cryst al must also be on the same frequency as your transmitter . Note that the Micro 555 receiver uses a dual
conversion FM Hitec crystal.

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

Need help or have any questions? Call us at 1-714-963-0329 or send us an email to service@globalhobby.net
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.
Page 9
❑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.

Page 10
❑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.

Page 11
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.

11
Page 12
❑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 service@globalhobby.net
Page 13
❑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
❑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
Page 14
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
panels together firmly until the epoxy sets up - about 10
minutes.
Before the epoxy sets up, double-check that the top of
☞
the wing is flat.
❑After the epoxy has cured, apply a strip of clear plastic
tape (not included) to the top of the wing, over the center
section joint, from the leading edge to the trailing edge.
❑Trim the ends of the tape flush with the wing using a
modeling knife.
❑Using the same technique, apply a strip of clear plastic tape over the center section joint on the bottom of the wing.
14
Need help or have any questions? Call us at 1-714-963-0329 or send us an email to service@globalhobby.net
Page 15
❑Apply two long strips of clear plastic tape to the bottom of
the wing. Apply the strips of tape down the middle of the
wing, perpendicular to the center section joint, from wing tip
to wing tip.
These strips of tape help strengthen the wing. Do not
☞
omit this procedure.
Step 3: Installing the Aileron Torque Rods
❑Test-fit each prebent torque rod into the molded grooves in the top of each wing panel. The top of each torque rod
should be even with the top of the wing.
There is a left and right torque rod. Note that the longer, smooth end of the torque rods goes into the ailerons.
☞
IMPORTANT
So the torque rods lay flat in the molded grooves, you may need to carefully cut the strip of clear tape where it crosses over
the grooves.
❑Mix a small quantity of 5 minute epoxy and use it to glue
the torque rods into ONLY the ailerons as shown. Remove
any excess epoxy using a paper towel and rubbing alcohol,
and allow the epoxy to set up before proceeding.
WARNING
Do not glue the torque rods to the wing or to the leading edge
of the ailerons. If you do this, the ailerons will be glued solid
and won't be able to pivot up and down.
❑After the epoxy has set up, apply one piece of aileron
reinforcement board onto each aileron to secure the torque
rods firmly into place.

15
Page 16
Step 4: Installing the Wing Reinforcement Board
❑Using 220 grit sandpaper with a sanding block, carefully
sand the trailing edge of the wing straight so that the wing will
fit into the wing saddle.
Check the fit often with the fuselage so you don't remove
☞
too much material.
❑Using a modeling knife and a ruler , cut a 1/4" x 1/2" hole
in the middle of the trailing edge reinforcement board.
This hole will prevent the reinforcement board from
☞
interfering with the aileron torque rods.
IMPORTANT
Before installing the trailing edge reinforcement board in the next procedure, make sure that both aileron torque rods are
completely down in the molded grooves.
❑Remove the protective backing from the trailing edge
reinforcement board.
❑Carefully apply the reinforcement board to the top of the
wing, making sure the board is centered over the centerline of
the wing and the back edge of the board is even with the
trailing edge of the wing.
❑Flex the ailerons up and down several times to make sure the torque rods are not sticking to the reinforcement board.
❑Carefully remove the protective backing from the wing reinforcement board.

Page 17
Step 5: Mounting the Wing to the Fuselage
❑Carefully apply the reinforcement board to the top of
the wing, making sure that it's centered over the wing's
centerline and that the back edge of the reinforcement board
is about 1/8" in front of the trailing edge reinforcement board.
It's very important to the integrity of the wing that the
☞
reinforcement board be adhered to the wing along its entire
surface.
❑Glue the 3mm x 20mm x 40mm plywood plate to the
bottom of the wing using a thin layer of 5 minute epoxy. The
plate should be centered over the wing's centerline and the
back edge of the plate should be even with the trailing edge.
It's important that the plate be centered over the wing's
☞
centerline. If it's not, the radiator scoop will not align properly
with the fuselage when it's installed later.
❑Carefully drill a 7/64" diameter hole, 3/4" deep, in the
center of the leading edge of the wing, making sure to drill the
hole straight and not at an angle.
IMPORTANT
Take care to drill the hole exactly in the center of the leading
edge. It helps to first make a small pilot hole using the tip of
your modeling knife.
❑T est-fit the 30mm long fiberglass dowel into the hole. The
dowel should be pushed into the hole deep enough so that
3/8" of it is beyond the leading edge. It is also important that
the dowel be straight and not angled up, down or side to side.
❑When satisfied with the alignment, glue the dowel into place
using a generous amount of 5 minute epoxy. Remove any
excess epoxy using a paper towel and rubbing alcohol, and
hold the dowel in place and aligned until the epoxy sets up.

❑Using a ruler and a pencil, carefully mark the location of
the wing dowel hole at the front of the wing saddle. The hole
should be located on the centerline of the fuselage (the mold
seam) and 7/16" up from the bottom of the fuselage.
❑Using the tip of your modeling knife, make a small pilot
hole in the fuselage at the mark you drew.
❑Using a 1/8" drill bit, carefully drill a hole through the
fuselage, using the pilot hole as your guide.
When drilling the hole, try to drill it parallel with the
☞
bottom of the fuselage.
❑Place the wing into the wing saddle and push the trailing edge down firmly into place.
Double-check that the dowel in the leading edge of the wing fully engages the hole in the fuselage. You may have to
☞
push the wing forward firmly and/or make fine adjustments to the hole so that the front of the wing sets properly in the wing
saddle.
❑Carefully align the centerline of the wing (the center joint), at the trailing edge, with the centerline of the fuselage (the
mold seam).
❑While holding the wing firmly in place and aligned, drill a
5/64" diameter hole into the middle of the plywood plate and
down through the wing screw plate glued inside the fuselage.
❑Remove the wing from the fuselage and enlarge only the hole in the wing using a 1/8" drill bit.
❑Place the wing back into the wing saddle and secure it into place using the 3mm x 18mm wood screw.
Do not overtighten the screw. You don't want to crush the wing.

Step 6: Installing the Plastic Radiator Scoop
❑Using a pair of scissors, cut out the radiator scoop along
its molded base, leaving about 3/32" of material to use as a
gluing surface. Cut out the back of the radiator scoop along
the molded scribe line, too.
❑Using 220 grit sandpaper with a sanding block, sand the
edges of the radiator scoop smooth and straight.
❑T est-fit the radiator scoop to the bottom of the wing. There
should be a 1/16" gap between the back edge of the scoop
and the fuselage, and the sides of the scoop should be even
with the sides of the fuselage.
❑While holding the radiator scoop in place and aligned, use a pencil to carefully mark the location of the wing screw onto
the bottom of the scoop.
❑When satisfied with the fit, remove the radiator scoop
and carefully drill a 5/16" diameter hole through it so you can
access the wing screw.
❑Test-fit the radiator scoop onto the wing once more to double-check that the hole lines up over the wing screw.
❑When satisfied with the alignment, mix a small quantity of 5 minute epoxy and apply a thin layer to the gluing surfaces
on the bottom of the radiator scoop.
❑Set the radiator scoop back into place and realign it. Remove any excess epoxy using a paper towel and rubbing
alcohol, and hold the scoop in place until the epoxy sets up.
WARNING
Be careful not to get any epoxy between the wing and the fuselage!

A fiberglass dowel is provided to strengthen the horizont al stabilizer . For the strongest joint possible, it's important that
the dowel be installed correctly. When installing the dowel, two things are very important: the dowel should be glued
along its entire length (making sure it is pushed firmly into the precut channel) and the stabilizer must be flat when you
glue the dowel into place. This will ensure you don't build a warp into the stabilizer.
❑Mix a small quantity of 5 minute epoxy and apply a thin layer inside the precut channel in the bottom of the
horizontal stabilizer.
❑Line up the ends of the dowel with the ends of the stabilizer
and carefully push the dowel into the channel. Remove any
excess epoxy using a paper towel and rubbing alcohol, and
use short pieces of masking tape to hold the dowel in place
until the epoxy sets up.
IMPORTANT
When gluing the dowel into place it's important that the dowel
be glued securely into the channel and that the stabilizer be
perfectly flat during the drying process.
❑After the epoxy has cured, remove the pieces of masking tape and carefully sand the ends of the dowel even with the
ends of the stabilizer.
❑Remove the protective backing from the 320mm long piece of white tape and apply the tape to the bottom of the
stabilizer , over the fiberglass dowel. Trim the ends of the tape even with the ends of the stabilizer using a modeling knife.

Step 2: Installing the Elevator Joiner Wire
❑Place the prebent elevator joiner wire onto the bottom of the elevator halves.
❑Center the wire over the middle of the elevator halves,
making sure that the front of the wire is even with the beveled
leading edges of the elevators.
❑When satisfied with the alignment, push the wire down
firmly to make an impression of the wire in the foam.
❑Remove the wire and set it aside.
❑Using a ruler and a modeling knife, carefully cut a very
shallow groove in each elevator half using the impression left
in the foam as a guide.
Don't cut too deeply. You don't want to cut through the
☞
top of the elevators.
❑Test-fit the joiner wire into the elevators. When pushed into place, it should be flush with the bottom of the elevators
and fit firmly in the grooves.
❑Mix a small quantity of 5 minute epoxy and carefully glue the joiner wire into place. Remove any excess epoxy using
a paper towel and rubbing alcohol, and hold the elevators flat until the epoxy sets up.
IMPORTANT
During the drying process, double-check that the elevator halves are both flat on your work table.
❑After the epoxy has set up, carefully apply one piece of
elevator reinforcement board over each end of the elevator
joiner wire.
IMPORT ANT
Make sure each piece covers the entire end of the joiner wire.

Step 3: Installing the Stabilizer Mounting Board
❑Using a ruler and a pencil, draw a centerline across the
top and bottom of the horizontal stabilizer, perpendicular to
the trailing edge.
Make sure the centerline is exactly in the center of the
☞
stabilizer.
❑Using a pencil, draw a centerline mark on the front and back edges of both pieces of horizontal stabilizer mounting board
(the two tapered-shaped pieces). These marks will help you align the mounting board with the centerline of the stabilizer.
IMPORTANT
Before installing the mounting board in the next procedure, look at the shape of the two pieces carefully.
end of each piece should be toward the trailing edge of the stabilizer.
❑Remove the two pieces of mounting board from the
protective backing.
❑Apply the two pieces of mounting board to the top and
bottom of the horizontal stabilizer. The back edge of each
piece should be even with the trailing edge of the stabilizer,
and the centerline marks you drew on the front and back of
the mounting board should line up with the centerline you drew
on the top and bottom of the stabilizer.
❑Apply the remaining two pieces of stabilizer mounting
board to each side of the vertical stabilizer. The back edge
of each piece of mounting board should be 1/4" in front of the
trailing edge of the stabilizer and the bottom of each piece should
be even with the bottom of the stabilizer.
The narrower
Step 4: Installing the Horizontal Stabilizer
Do not epoxy the stabilizer to the fuselage. Because of the plastic that the fuselage is molded from, even roughening
the surface will not allow the epoxy to adhere strong enough to hold the stabilizer securely . Screwing the stabilizer into
place, while different from other models, actually works very well and results in a very secure joint.
22

Page 23
❑Cut out each of the three stabilizer mounting slots in the
back of the fuselage. The easiest way to do this is to first
carefully sand the outside of the slots until the edges of the
flanges begin to show through. At this point the plastic will be
thin enough that you can easily cut out the remaining plastic
with a modeling knife.
You will need to cut a slot in the back of the fuselage so
☞
that the stabilizer can be slid into place.
❑Using a 1/16" drill bit, carefully drill eight holes through
the horizontal stabilizer mounting flanges. Drill two holes
through the top and bottom of each of the flanges. The
rear holes should be 3/8" in front of the back of the fuselage
and the front holes should be 1-7/8" in front of the back of
the fuselage.
Drill the holes nearer the fuselage sides. This will ensure
☞
the screws don't miss the mounting board when you install
them later.
❑Using a modeling knife, carefully trim away the plastic burrs left from drilling the holes.
❑Mount the wing securely to the fuselage, then slide the horizontal stabilizer into place. Push the stabilizer as far
forward as possible and align the outer edges of the reinforcement board with the outer edges of the mounting flanges.
❑With the wing mounted to the fuselage and the stabilizer
in place, look carefully from the front of the fuselage at both
the wing and the stabilizer. When aligned properly, the
stabilizer should be level with the wing. If it is not level, use a
modeling knife and/or 220 grit sandpaper and adjust the
mounting flanges until the correct alignment is achieved.
It may be necessary to use thin shims between the flanges
☞
and the stabilizer to align it properly to the wing.
❑Now check to make sure that the tips of the stabilizer are
equal distances from the tips of the wing. Use a ruler and
measure from one wing tip to the stabilizer tip on the same
side. Do this for both sides. When the stabilizer is aligned
properly, both of these measurements should be the same.
Visit our website at http://watt-age.globalhobby.com for information on other Wattage products

Page 24
❑When satisfied with the alignment, use a couple of pieces of masking tape to hold the stabilizer in place.
❑Using the tip of your modeling knife, make very small
pilot holes in the stabilizer moun t i n g board u s i n g the h o l e s
you drilled in the mounting flanges as a guide.
❑Install and lightly tighten the eight 1.5mm x 4mm wood
screws to hold the stabilizer firmly in place.
Be careful not to overtighten the screws or you will strip
☞
the mounting board.
Step 5: Installing the Vertical Stabilizer
❑Slide the vertical stabilizer into place and align it. When
aligned properly , the back edge of the stabilizer should be even
with, and at the same angle as, the back of the fuselage. The
angle cut into the front of the stabilizer should also be even
with the molded angle in the top of the fuselage.
24
❑With the vertical stabilizer in place, look carefully from
the front of the airplane to check that the vertical stabilizer is
aligned 90º to the horizontal stabilizer. If it does not line
up, use a modeling knife and/or 220 grit sandpaper to trim
the mounting flanges until the correct alignment is achieved.
❑When satisfied with the alignment, install the vertical
stabilizer using the same technique as the horizontal stabilizer .
The only difference is the locations of the holes for the screws.
The two rear holes should be 5/8" in front of the back of the
fuselage and the two front holes should be 2-1/2" in front of
the back of the fuselage.

If you plan on strictly flying your P-51 Reno Racer off of grass we suggest not installing the tail wheel assembly. It
won't be necessary for landing on grass.
❑Using 220 grit sandpaper with a sanding block, carefully
sand a shallow V-shaped bevel in the leading edge of the
rudder.
This will allow right and left movement of the rudder while
☞
keeping the hinge gap to a minimum.
WARNING
Make sure you sand the bevel into the leading edge and not
the trailing edge.
❑Hold the rudder against the vertical stabilizer, making sure the top of the rudder is even with the top of the stabilizer.
❑Using a pencil, mark on the leading edge of the rudder, the area that must be removed to clear the elevator joiner wire.
IMPORTANT
Before making the cutout in the next procedure, it's important
that you leave at least 1/2" of material between the bottom of
the rudder and the bottom of the cutout for the elevator joiner
wire. This will ensure that there is room to install the tail wheel
wire and the rudder control horn.
❑Using a modeling knife, carefully cut away the portion of
the rudder to clear the elevator joiner wire.

Page 26
❑Measure down 1/2" from the top of the rudder, at the leading edge, and draw a mark. Measure down 2-1/2" from the
top of the rudder, at the leading edge, and draw a mark.
❑Carefully hand-drill a 1/16" diameter hole into the rudder, for the hinges, at each mark you drew.
Be careful to drill the hole perpendicular to the leading edge and not at an angle. Also be careful that you don't drill out
☞
through the side of the rudder.
❑Apply a thin layer of lightweight oil or Vaseline to the pivot
point of each hinge.
❑Mix a small quantity of 5 minute epoxy and glue the two
hinges into only the rudder. Remove any excess epoxy
using a paper towel and rubbing alcohol, and allow the epoxy
to set up.
Push the hinges into the rudder far enough so that one-
☞
half of the pivot point is recessed into the leading edge.
❑After the epoxy has set up, pivot the hinges back and forth several times to loosen the pivot points.
❑Align the rudder with the vertical stabilizer and carefully mark the locations of the two hinges onto the stabilizer.
❑Carefully hand-drill a 1/16" diameter hole into the stabilizer at each mark you drew.
❑Apply a thin layer of lightweight oil or Vaseline to the pivot point of each hinge.
❑Hinge the rudder to the stabilizer, using 5 minute epoxy.
Remove any excess epoxy using a paper towel and rubbing
alcohol, and allow the epoxy to set up.
When hinged properly, there should be little or no gap
☞
between the rudder and the stabilizer.
❑After the epoxy has set up, pivot the rudder back and forth several times to loosen the hinges' pivot points.
Step 2: Installing the Tail Wheel Assembly
❑Using a modeling knife, carefully cut a thin slot in the
bottom of the rudder, deep enough for the tail wheel tiller arm
to be pushed down into.
26
Need help or have any questions? Call us at 1-714-963-0329 or send us an email to service@globalhobby.net
Page 27
❑Place the tail wheel bracket onto the bottom of the
fuselage. T o align the assembly , the tail wheel tiller arm should
fit down into the slot you cut in the rudder, the pivot point of
the tiller arm should be even with the rudder hinge line and
the bracket should be centered in the middle of the fuselage.
You will need to cut a small notch in the leading edge of
☞
the rudder for the tiller arm boss.
❑When satisfied with the alignment, remove the tail wheel assembly and apply a couple of drops of lightweight oil or
Vaseline to only the pivot point of the tiller arm.
❑Mix a small a small quantity of 5 minute epoxy and use it to glue only the tiller arm into the bottom of the rudder. Before
the epoxy sets up, carefully secure the the plastic bracket to the fuselage using the two 2mm x 5mm wood screws provided.
Make small pilot holes for the wood screws using the tip of your modeling knife.

Page 28
❑Test-fit the two servos into the radio tray. If the servos
are too large to fit, use a modeling knife to enlarge the hole in
the radio tray to accommodate the servos.
Both of the servos' output shafts should face toward the
☞
front of the fuselage.
❑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 radio tray.
Step 2: Installing the Nylon Control Horns
❑Using a 1/8" drill bit, carefully drill the elevator and rudder pushrod exit holes through the back of the molded fairings
in the sides of the fuselage.
❑Using a ruler and a pencil, measure out 3/8" from the inside edge of the right elevator half (at the hinge line) and draw
a mark on the bottom of the elevator.
This mark is how far out the nylon control horn needs to be installed on the elevator.
☞
❑Use a pencil to mark the location and size of the slot that
needs to be cut through the elevator to install the nylon
control horn. T o make this easy , use the control horn backplate
as a guide as shown.
So the control horn lines up properly with the pushrod,
☞
the slot needs to be angled slightly toward the fuselage side.
❑Using a modeling knife, carefully cut a slot through the elevator only large enough for the tip of the control horn to be
pushed through.
❑From the top of the elevator, push the control horn up through the slot. When in place, the tip of the control horn should
face the bottom of the elevator.
❑Making sure that the flat portion of the control horn
backplate faces away from the elevator, push the backplate
over the end of the control horn until you hear it "click" firmly
into place.
Because the elevator is thick, we cut a recess in the
☞
elevator so that the backplate could be attached without
crushing the foam.
28

Page 29
❑Install the rudder control horn using the same method
as the elevator control horn. The centerline of the control
horn should be 1/4" up from, and parallel to, th e bottom edge
of the rudder.
The cut that you make in the rudder to install the control
☞
horn will be right below the portion of the tail wheel wire that's
glued into the rudder.
As with the elevator control horn, we recessed the rudder control horn backplate so it would snap easily into place.
☞
Also note that the tip of the rudder control horn is opposite the elevator control horn.
Step 3: Installing the Elevator & Rudder Pushrods
❑Plug the elevator and rudder servo leads into their proper slots in your receiver. Plug the ESC lead into your receiver
and plug the flight battery into your ESC . Turn on your 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, slide the plain
end of the pushrod wire through the pushrod exit hole in the
fuselage side, then carefully snap the clevis into the elevator
control horn.
❑Place a "single arm" servo horn onto the elevator servo (the servo on the opposite side of the elevator control horn),
making sure that the servo horn is centered and points toward the fuselage side. The arm should have at least two
holes in it.
❑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.
Visit our website at http://watt-age.globalhobby.com for information on other Wattage products
29
Page 30
❑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.
❑Remove the servo horn. Using a 1/16" drill bit, enlarge the hole in the servo arm that is 1/4" out from the center of the
servo horn.
❑Attach the servo horn to the Z-Bend, then attach the servo
horn to the servo, making sure it's centered.
❑Install and tighten the servo horn retaining screw , 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.
IMPORTANT
So that the two pushrod wires don't touch each other where they cross inside the fuselage, install the rudder pushrod wire
so that the long portion of the wire is on the opposite side of the servo arm from the elevator pushrod wire. Doing this will
put the pushrods at slightly different heights, so they won't rub against each other.
❑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 4: Installing the Aileron Servo
❑Install the rubber grommets and brass collets onto the servo mounting lugs.
❑Using a ruler and a pencil, measure back 2-3/4" from the leading edge of the wing (at the centerline) and draw a mark
at this location. Do this on the top of the wing.
❑Place your aileron servo on top of the wing, aligning the
servo output shaft with the mark you drew.
❑Center the servo over the wing's centerline and trace
around the base of the servo using a pencil.
❑Using a modeling knife, carefully cut out the wing to accommodate your servo. Don't cut the hole too large, though.
The servo should fit tightly.
WARNING
For the servo mounting lugs to fit down against the top of the wing, you'll need to remove as much of the foam as possible
from the bottom of the servo cutout. Be careful not to cut through the bottom of the wing!

Page 31
❑Push the servo into the cutout making sure that the servo
output shaft is toward the leading edge of the wing.
You will need to cut a notch in the side of the cutout for
☞
the servo wire to exit the top of the wing.
❑Install the servo using the mounting screws provided with your servo.
To make it easier to install the screws first punch a small pilot hole through the wing reinforcement board using the tip
☞
of your modeling knife.
Step 5: Installing the Aileron Pushrods
❑Carefully thread the two nylon adjustable control horns
onto the aileron torque rods. The openings in the control horns
should face up and toward the leading edge of the wing, and
the top of the control horns should be even with the top of the
torque rods.
IMPORTANT
So both ailerons have the same amount of control throw, make
sure that both control horns are even with each other.
❑Plug the aileron servo lead into its proper slot in your receiver . Plug the ESC lead into your receiver and plug the flight
battery into your ESC . Turn on your radio system and center the servo using the aileron trim lever on your transmitter.
❑Thread one nylon clevis onto each of the two 1.5mm x 150mm threaded pushrod wires. Thread the clevises on far
enough to leave room for adjustments later.
❑Carefully snap each of the clevises into the adjustable control horns.
❑Place a "dual arm" servo horn onto the aileron servo, making sure that the servo horn is centered.
Each arm should have at least three holes in it.
☞
❑With the servo horn and both ailerons centered, use a pencil to draw a mark on each pushrod wire where it crosses the
hole that is 1/4" out from the center of the servo horn.
If you're using a CS-10 servo, this is the first hole out from the center of the servo horn.
☞
❑Make a Z-Bend in each pushrod wire at the mark you drew. Use wire cutters to remove the excess wire.

❑Attach the servo horn to the Z-Bends, then attach the
servo horn to the servo, making sure that it's centered.
Y ou will have to enlarge the holes in the servo arms using
☞
a 1/16" drill bit so that you can attach the pushrods.
❑Install and tighten the servo horn retaining screw , provided
with your servo, to secure the servo horn into place.
SECTION 12: MAIN LANDING GEAR INSTALLATION
YOU'LL NEED THE FOLLOWING PARTS:
❑ (2) Prebent Main Landing Gear Wires
❑ (2) Plastic Main Gear Wheels
❑ (2) Plastic Main Gear Wheel Retainers
If you plan on strictly flying your P-51 Reno Racer off of grass we suggest not installing the main gear assembly. The
main gear is not necessary for landing on grass and will only cause complication.
❑Carefully push the prebent loop in each landing gear wire
through the molded slot in the two nylon landing gear mounts.
If you ever want to remove the landing gear after it has been glued to the wing, you can simply squeeze the prebent
☞
loop together and pull the wire from the nylon mount.
32
Need help or have any questions? Call us at 1-714-963-0329 or send us an email to service@globalhobby.net
Make sure the prebent loop is pushed into the slot as far
☞
as possible as shown.
Page 33
Step 2: Aligning the Landing Gear Assemblies
❑Using a ruler and a pencil, measure out 3-1/4" from the
centerline of the wing and draw a mark on the bottom of the
wing just behind the leading edge.
❑Measure back 5/8" from the leading edge of the wing, at the first mark you drew, and draw a second, intersecting mark.
❑Repeat the same procedures on the other half of the wing.
❑Place one landing gear assembly onto the bottom of
the wing. The inside and front edges of the nylon mount-
ing plate should be aligned with the two marks you drew and
the inside edge of the mounting plate should be parallel withthe centerline of the wing.
IMPORTANT
The landing gear axle should point out toward the tip of the wing and the prebent coil should be toward the trailing edge.
❑When satisfied with the alignment, hold the assembly in place and trace around the mounting plate using a pencil.
Step 3: Installing the Landing Gear Assemblies
❑Remove the landing gear assembly and use 220 grit sandpaper to roughen the bottom of the nylon mounting plate and
the surface of the wing where the plate will be glued into place (inside the outline you drew).
WARNING
Not roughening both the bottom of the mounting plate and the area of the wing where the plate will be glued will result in the
landing gear assembly popping off during landing. The gluing surfaces must be roughened for the epoxy to adhere
properly.
❑Glue the landing gear assembly to the bottom of the wing using a generous amount of 5 minute epoxy . Remove any
excess epoxy using a paper towel and rubbing alcohol, and hold the assembly in place until the epoxy sets up.
❑After the epoxy has set up, repeat the previous procedures to install the second landing gear assembly on the other

correctly, it will "snap" into place.
Step 2: Installing the Receiver
The locations of the radio equipment shown in the next few steps is only approximate. This is how our test airplanes
were set up. The locations of your radio equipment could differ and should be dependent on what type of equipment
you use and where you balance your airplane. Balancing will be done in the next section.
❑Plug the elevator and rudder servo leads into their proper slots in the receiver.
❑Uncoil the receiver antenna and feed it through the inside of the fuselage and out the back. As an alternative, you
could drill a small hole in the side of the fuselage and run the antenna out through that, then secure it to the back of the
fuselage using a small piece of clear decal.
IMPORTANT
If you run the antenna through the inside of the fuselage, make sure that the antenna is not wrapped around or otherwise
touching any of the pushrod wires or radio interference could result.
❑Mount the receiver on the radio tray , in front of the servos,
using a small piece of double-sided tape.
Step 3: Installing the Electronic Speed Control
❑Carefully solder the motor wires to your ESC, being careful that the polarity is correct.
Make sure to use heat-shrink tubing to insulate the solder joints.

❑Mount the ESC to the fuselage side, as far away from
the receiver as possible. Use a small piece of double-sided
tape to hold it in place.
Mounting the ESC as far away from the receiver as
☞
possible will reduce the chance of radio interference.
❑If your ESC has an on/off switch, mount it to the fuselage side in front of the wing saddle.
We don't suggest mounting the switch in the radio compartment, because it might interfere with the aileron servo when
☞
the wing is mounted.
Step 4: Installing the Flight Battery
❑Set the flight battery onto the battery tray and slide it
through the nylon tie-down strap.
❑Hold the flight battery in place and pull the tie-down strap
to tighten the flight battery down firmly.
T o remove the flight battery, push the tab on the tie-down
☞
strap to loosen it enough to pull the flight battery free.
The location of the flight battery shown above is only approximate. You may need to move it fore or aft to balance the
☞
airplane when that is done in the next section.
❑Using a modeling knife, carefully cut a 1/2" diameter air-exit hole in the bottom of the fuselage, about 1" behind the
back of the wing saddle. This hole, along with the air-intake hole in the front of the fuselage, will allow hot air to exit the
fuselage, keeping the flight battery from overheating.
Step 5: Applying the Decals
❑Working with one decal at a time, use a pair of scissors to carefully cut out the decal along its outer edges.
Notice that next to each large decal there is printed its location on the airplane.
☞
❑Remove the protective backing from the decal and apply the decal to the airplane. (Use the box cover photos to
position the decals.) Lightly rub the decal with a soft cloth to remove any trapped air from beneath it.
If any air bubbles form in the decal you can "prick" the bubble with a straight pin to release the air.
☞
❑Repeat the steps above to apply the remaining decals. Rub each decal down thoroughly to adhere it into place.

SECTION 15: BALANCING THE P-51 RENO RACER EP
YOU'LL NEED THE FOLLOWING TOOLS AND SUPPLIES:
❑ Ruler
IMPORTANT
It is critical that your airplane be balanced correctly. Improper balance will cause your airplane to lose control and crash!
Center of Gravity Location:
2-3/8" back from the leading edge of the wing, at the fuselage sides.
WARNING
This location is recommended for initial test flying. The C.G. can be moved forward or aft up to 1/4", but it is not
recommended that the C.G. be located any farther back than 2-5/8".
IMPORTANT
As you move the C.G. further aft, the airplane will become more responsive, especially in pitch. Do not start to move the
C.G. back until you are comfortable with the flight characteristics of the airplane.
Balance the P-51 Reno Racer EP with the flight battery installed.
☞
❑Measure and draw two marks on the top of the wing, 2-3/8" back from the leading edge, at the fuselage sides.
❑Turn the airplane upside down, place your fingers on the marks, and carefully lift the airplane. If the nose of the
airplane falls, the airplane is nose heavy. To correct this, move the flight battery back far enough to bring the airplane into
balance. If the tail of the airplane falls, the airplane is tail heavy. To correct this, move the flight battery forward enough to
bring the airplane into balance. When balanced correctly , the airplane should sit level or slightly nose down when you lift
it up with your fingers at the C.G. location.
❑ Pencil
Once you have flown and become familiar with the flight characteristics of the airplane, the C.G . can be moved forward
☞
or aft up to 1/4" in each direction to change the flight performance. Moving the C.G . back will cause the airplane to be more
responsive, but less stable. Moving the C.G. forward will cause the airplane to be less responsive, but more stable.
Do not fly the airplane beyond the recommended balance range or an uncontrollable crash could result!
SECTION 16: CONTROL THROWS
We recommend setting up the P-51 Reno Racer EP using the control throws listed below. These control throws are
suggested for initial test-flying because they will allow the airplane to fly smoother and make it easier to control.
TEST-FLYING
Ailerons:3/16" Up3/16" Down
Elevator:1/4" Up1/4" Down
Rudder:1/2" Right1/2" Left
When measuring the control throws, measure from the widest point of the control surfaces.
☞

Page 39
Once you're familiar with the flight characteristics of the airplane, you might want to increase the control throws to the sportflying settings listed below. These control throws will make the airplane more responsive and allow you to do basic
aerobatics with ease.
SPORT-FLYING
Ailerons:5/16" Up5/16" Down
Elevator:5/16" Up5/16" Down
Rudder:3/4" Right3/4" Left
We do not suggest increasing the control throws beyond the recommended Sport-Flying settings. Higher control
throws will cause the airplane to be extremely control-sensitive and result in a possible crash if you are not careful.
SECTION 17: PREFLIGHT CHECK & SAFETY
●
Check the operation of the throttle. To do this, do the following:
A) Plug the flight battery into the ESC and turn on the radio system.
WARNING
Do not turn the receiver on unless the transmitter is turned on first. Always turn the transmitter on first. Never allow hands
or clothing to get in the way of the propeller when the radio is turned on. Sudden unwanted radio signals, or turning the
radio on with the throttle stick set at full throttle, can turn the motor on unintentionally. Always make sure that the throttle
control stick is set to idle before turning on the transmitter.
B) When the throttle control stick is at the idle position, the motor should be off. Moving the stick forward should
turn on the motor. Gradually moving the stick to the full forward position should result in the motor running at full power.
Some ESCs will give you more proportional control than others. Y our ESC may also have a manual control adjustment
☞
screw that must be adjusted prior to using the ESC. (Refer to your ESC's operating guide for further information.)
●
Cycle the flight battery three times. When NiMH batteries are new they need to be used 2-3 times before they will
produce their top voltage and duration. To cycle them, simply charge the battery and then run the motor (at low speed to
prevent damaging it) until the motor stops. Allow the battery and motor to cool, then repeat this procedure two more times.
●
Check the condition of the transmitter batteries. They should be fully charged.
●
Check every glue joint in the airplane to ensure that everything is tight and well-bonded.
●
Double-check the balance of the airplane. Do this with the flight battery installed.
●
Check the control surfaces. They should move in the correct direction and not bind.
●
Check to ensure that the control surfaces are moving the proper amount.
●
Check the receiver antenna. It should be fully extended and not coiled up inside the fuselage.
●
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.

The following are our general guidelines for your safety and the safety of others. Please read and understand
these safety guidelines before going out to the flying field for the first time.
●
Do not test-fly your model for the first time without first having it safety-checked by an experienced modeler.
●
Do not fly your model higher than approximately 400 feet within 3 miles of an airport without having an observer with
you. The observer should tell you about any full-size aircraft in your vicinity and you should always give the right-of-way to
full-scale aircraft.
●
When flying at a flying field with established rules, you should abide by those rules. You should not deliberately fly your
model in a reckless and/or dangerous manner.
●
While flying, you should not deliberately fly behind the flight line. If your model should inadvertently fly behind the flight
line, you should change course immediately.
●
You should complete a successful range check of your radio equipment prior to each new day of flying, or prior to the
first flight of a new or repaired model.
●
You should perform your initial turn after take- off away from the flightline and/or spectator area.
●
Y ou should not knowingly operate your R/C radio system within 3 miles of a preexisting model club flying field without a
frequency sharing agreement with that club.

SECTION 18: FLYING THE P-51 RENO RACER EP
The P-51 Reno Racer EP can take off from the ground or be hand-launched. We recommend ground take-offs only from
hard smooth surfaces.
Taking Off from the Ground
With the airplane pointing into the wind, apply full power and feed in right rudder to keep the airplane tracking straight as it
rolls down the runway. Once sufficient airspeed has been reached, gently apply up elevator to lift the airplane off the
ground. Climb out straight ahead in a shallow climb to build up speed. Do not make any steep turns right after take-off or
you may stall the airplane.
Hand Launching
Hand Launching should always be done into the wind.
T o hand-launch the airplane, gently grasp the fuselage directly behind the wing using your thumb and forefingers. Hold the
airplane above shoulder level and turn on the motor to full power. With the motor running at full power, firmly throw the
airplane straight ahead and level. Do not throw it up at an angle or throw it too hard or out of control. Let the airplane fly
straight and level to pick up airspeed, then climb to your desired altitude. Be careful not to climb too steeply after handlaunching or you could stall the airplane.
In the Air
In the air the P-51 Reno Racer EP is smooth and predictable. At full power, the airplane is fast and responsive to control
inputs, and handles light winds with ease. It "grooves" around corners and is rock-steady while "up on the wing." Loops,
rolls, Immelmann turns, cuban eights, spins and other aerobatics are completed without much effort. You will find the
airplane tracks very true and stays where you put it.
Landing
Landings should always be done into the wind.
Prepare for landing by reducing power and making a shallow turn into the wind. (With power off we strongly suggest
avoiding high-banked turns.) With the airplane on final approach it will begin to slow down and descend. With the
airplane descending, apply small amounts of up elevator to slow the airplane's speed. Just before touch-down, turn the
motor off and let the airplane settle near the ground. Flair just before touch-down and you will be rewarded with a soft
landing. As always, when landing, be careful not to over-control. Over-controlling leads to excessive oscillations which
don't make for good landings.
