On July 25, 1909, French aviator, inventor and engineer Louis Charles Joseph Blériot (pictured at
below center) made the first flight across the English Channel in a heavier-than-air aircraft, a Blériot XI.
This historic achievement not only won Blériot a lasting place in history but assured the future of his
aircraft manufacturing business. The Blériot XI was eventually sold with various wingspans and as
single- and two-seat versions, marketed as trainers, sport/touring, military, and racing/exhibition
aircraft with several different types of engine, including the famous Anzani 3-cylinder fan (or semi-
radial) engine. Like its predecessor, it was a tractor-configuration monoplane, with a partially covered
box-girder fuselage built from ash with wire cross bracing.
Harriet Quimby (pictured at above right) was America’s first licensed woman pilot. In 1912 she flew
a Blériot XI from England to France across the English Channel. The first Blériot XIs entered military
service in Italy and France in 1910, and a year later, some of those were used in action by Italy in North
Africa –the first use of an aircraft in a war –and in Mexico. The Royal Flying Corps received its first
Blériots in 1912. During the early stages of the First World War, eight French, six British and six Italian
squadrons operated various military versions of the aircraft, mainly in observation duties, but also as
trainers, and in the case of single-seaters, as light bombers with a bomb load of up to 25 kilograms, just
over 55 pounds in traditional American units.
The above photo shows an optional U35425 motor, propeller,
dummy engine and simulated vintage-style spoked wheels.

Our radio-controlled Blériot XI is approximately 1/6 scale and suitable for a 3 or 4 channel radio.
Like the original, it features a balanced all-moving vertical rudder and a lifting horizontal tailplane that
is fitted with full-flying elevator surfaces at each end that rotate together on a torque rod extending
through the fixed inner section. The Blériot XI, like many early aircraft, was designed with wing-
warping, which may be replicated for some radio-control models but only by a very few experienced
modelers. Wing-warping is not used in this model; instead, to enhance flight performance and safety,
we have added ailerons, which are not scale, but are easy for most beginner and intermediate pilots to
control. Advanced scale pilots who value appearance and are comfortable with slow turns may use tape
to fix the ailerons to the wing and fly with rudder, elevator and throttle only. (Factory-original Mylar is
available to order for covering the ailerons.) We tested a few different versions using different types
and combinations of composite materials to make this Blériot XI a stable sport-aerobatic flyer.
There have been lots of customers, such as Dennis K. Crouch and Wayne Wlocka, who recommended
we develop the Blériot XI. We thank them for their good advice and hope this ARF brings the fun of
flying to all our valued customers.

7. Before you begin assembly of this model airplane, read all instructions and test-fit each part to
ensure you fully understand the instructions and that no parts are missing, damaged or
unsatisfactory. (Note: Temperature and/or humidity differences between the factory, our
warehouse and your home or workshop may dictate the need for slight adjustments to the wing,
and/or the vertical or horizontal tail surfaces to ensure proper alignment; however, we recom-
mend you contact us before you attempt any such adjustments.)
8. To help ensure the security of the optional servo connections, we recommend use of
optional Maxford USA servo-extension safety clips.
9. If you are not an experienced R/C pilot or have not flown this type of model before,
we strongly urge you to get assistance from an experienced R/C pilot.
10. You may use 30-minute epoxy to attach critical parts permanently (such as where the elevators
attach to their torque rod) and apply a threadlock compound to secure all airframe components
from vibration.
11. If you have any concern about the security of any factory fabrication procedure(s), you may apply
30-minute epoxy around the perimeter of such part(s) as an extra safety precaution.
12. This model may include some plastic, fiberglass and/or carbon-fiber-reinforced parts. If you drill,
grind or sand any such part, always wear safety goggles, a particle mask and rubber gloves to
guard yourself from eye, skin and respiratory-tract irritation; never blow into the part as the dust
may blow back into your face.
13. Check the Mylar covering material’s joints and surfaces; if necessary, carefully use an iron (do NOT
set the iron’s temperature too high) to secure the edges and to tighten any loosened areas.
Recheck and retighten from time to time.
14. Read all instructions included with your electric power system’s motor, speed control (ESC),
battery and charger. Failure to follow instructions could result in bodily harm and/or permanent
damage to the motor, ESC, battery and surroundings! If you crash this model airplane, check
whether the battery is damaged. Do NOT attempt to use or recharge a damaged battery.

VI. ASSEMBLY INSTRUCTIONS:
A. TAIL SECTION:
1. Use your radio or a servo tester to center the elevator and
rudder servos. (You may be interested to learn about servo
testers at http://www.maxfordusa.com/servo.aspx.)
2. Attach EZ-Link connectors to the output arms of the rudder
and elevator servos and use the hardware provided with your
servos to install them in the fuselage.
3. Mark the center of the approx. 16 1/4-inch long by
4mm-diameter composite elevator torque rod. Then,
while inserting the torque rod through its opening in
the horizontal tailplane, position the three wooden
elevator control-horn parts in the center of the torque
rod. (NOTE: Do NOT glue the wooden control-horn
parts together or to the torque rod at this time.)
4. Center the torque rod within the horizontal tailplane. Mark where the torque rod exits each end
of the horizontal tailplane. Help prevent the torque rod from being accidently glued to the
horizontal tailplane by applying petroleum jelly liberally to the torque rod on each side of the
opening for the elevator’s control horn and where the torque rod exits at both ends of the
horizontal tailplane.
5. Test-fit the left- and right-side
elevator panels onto the exposed
ends of the elevator torque rod.
Remove the elevators from the
torque rod.
6. Being careful to not allow any glue
to enter the horizontal tailplane,
apply CA adhesive or epoxy along
the outer length of the right-side
elevator’s torque rod.
Immediately insert this torque rod
into the right-side elevator. Check to
be sure the torque rod remains
centered in the horizontal tailplane
and is able to rotate freely within
the horizontal tailplane.

(NOTE: Do not to get any glue inside the horizontal tailplane. In the event of a minor gluing
accident, it may help to use a little acetone on the end of a Q-tip as a solvent.)
7. Allow the CA adhesive or epoxy to set fully or cure inside the elevator. When the CA adhesive or
epoxy has set or cured, check that the torque rod remains centered within the tailplane.
8. Being careful not to allow any glue to enter the horizontal tailplane, apply CA adhesive or epoxy
along the outer length of the left-side elevator torque rod. Immediately insert the torque rod fully
into the left-side elevator. Check that the torque rod remains centered within the horizontal
tailplane and able to rotate freely within the horizontal tailplane.
9. As shown below, before the CA adhesive or epoxy has fully set or cured, place the horizontal
tailplane, torque rod and elevator assembly on a flat surface with their flat lower surfaces facing
down and aligned to each other. Allow the CA adhesive or epoxy to set or cure fully.
10. With the horizontal tailplane, torque rod and elevator assembly on a flat surface (with the lower
surfaces facing down as shown above), center the three
elevator control-horn parts on the torque rod and point
the control horn straight up.
11. Firmly press the three wooden elevator control-horn
parts together on the torque rod. Apply thin CA adhesive
to secure the elevator control horn parts to each other
and to the torque rod.
12. Check that the torque rod is still able to rotate freely
within the horizontal tailplane.
13. As shown below, attach the horizontal tailplane beneath the tail booms.

14. Test-fit the rudder’s control horn to the rudder and test-fit the CA hinges and rudder to the
fuselage. If you will install the simulated cross-bracing wires for the tail boom, leave approx.
1/8-inch (3 mm) between the tops of the booms and the rudder; use a sharp hobby knife to open
the CA hinge slots in the rudder post and cut through any excess Mylar covering the CA hinge
slots in the rudder as necessary.
15. As shown at the right, use epoxy to
secure the rudder’s control horn to the
rudder.
16. Center the CA hinges in their slots and
use thin CA adhesive to attach the
rudder to the end of the fuselage.
17. Attach an EZ-Link connector to the
arms of the rudder and elevator servos.
18. As shown below, starting from the tail, guide the rudder’s and elevator’s composite pushrods
through the predrilled holes in the tail-boom’s formers and into the EZ-Link connectors on the
rudder and elevator servos.
19. Leave not less than 1/2-inch of pushrod length in front of each of the EZ Link connectors attached
to the servos to allow for ‘fine-tuning’ of the control surfaces. Snug, but do not tighten, the EZ Link
connectors to hold their pushrods gently but firmly.
20. Using the photos as a guide, mount the shock-absorbing tailwheel
assembly between the predrilled holes and secure this assembly in
position with C-rings. (NOTE: If an optional 2 1/2-inch vintage-style
spoked tailwheel will
be used, install it at this
time; or, the tailwheels
may be exchanged at
the end of each flying
session. You may learn
more about optional
spoked wheels at
http://www.maxfordusa.com/wheels.aspx.)
21. Twist a tailwheel steering horn fully onto
the bolt on the tailwheel strut.

22. Connect the steering-control pushrod’s clevis to the tailwheel steering horn. (NOTE: Do NOT
guide the tailwheel’s composite steering-control pushrod through any of the predrilled holes in
the tail boom’s formers.).
23. Apply masking tape to the rudder and tailwheel
to securely hold them in a straight-ahead position.
24. Check to be sure your rudder and elevator servos
remain centered.
25. As shown at the right and detailed below, use a
supplied short piece of piano wire with a Z-bend,
some CA adhesive and heat-shrink tubing to
attach the rudder’s pushrod to the right-hand
side of the rudder’s control horn: (NOTE: Do not
substitute with any heavier hardware items.)
a. Twist the piano wire’s Z-bend into the control
horn on the right side of the rudder.
b. Slide a piece of heat-shrink tubing onto the
rudder servo’s control rod and push it forward,
in front of where the Z-bend rod will be
attached to the rudder’s composite pushrod.
c. Use a high-speed motor tool’s cutoff wheel to
remove the portion of the rudder’s composite pushrod that extends behind the Z-bend in the
short piece of piano wire.
d. Apply and spread a drop of CA adhesive along the metal pushrod extending forward of the Z-
bend wire. While the CA adhesive is still wet, align and hold the rudder servo’s pushrod next to
the metal pushrod and slide the heat-shrink tubing back toward the tail, covering both the
composite and metal pushrods.
e. Confirm masking tape is still holding the rudder in a straight-ahead position. Being careful to
shrink evenly but not burn the heat-shrink tubing, apply heat from an electric soldering iron or
woodburning tool for a few seconds along the entire length of the heat-shrink tubing.
26. Use a supplied short piece of piano wire with a ‘Z-bend,’
some CA adhesive and heat-shrink tubing to attach the
tailwheel’s pushrod to the left-hand side of the rudder’s
control horn as shown at the right and detailed as
follows:
a. Twist the piano wire’s Z-bend into the control horn
on the left side of the rudder
b. Slide a piece of heat-shrink tubing onto the tail-
wheel’s composite steering-control pushrod, in front
of where the metal Z-bend rod will be attached to the
tailwheel’s composite pushrod.
c. Use a high-speed motor tool’s cutoff wheel to remove
the portion of the tailwheel’s pushrod that extends
behind the Z-bend in the short piece of piano wire.
d. Apply and spread a drop of CA adhesive along the
metal pushrod extending forward of the Z-bend in the wire. While the CA adhesive is still wet,
align and hold the tailwheel’s composite pushrod next to the metal pushrod and slide the heat-
shrink tubing back toward the tail, covering both the composite and metal pushrods. While the
CA adhesive is still wet, align and hold the rudder’s metal pushrod next to the tailwheel’s
composite steering-control rod and slide the heat-shrink tubing back toward the tail, covering
both pushrods.

Being careful to shrink evenly but not burn the heat-shrink tubing, apply heat from an electric
soldering iron for a few seconds along the entire length of the heat-shrink tubing. Remove the
masking tape from the rudder and tailwheel.
27. Use masking tape to hold the elevators in a level position (even with the horizontal tailplane).
28. Use the supplied short piece of piano wire that has both an offset-bend and a ‘Z-bend,’ some CA
adhesive and heat-shrink tubing to attach the composite elevator pushrod to the elevator’s
control horn as shown and detailed below:
a. Twist the piano wire’s Z-bend into the elevator’s
control horn.
b. Slide a piece of heat-shrink tubing onto the
elevator’s composite control rod; push it forward,
in front of where the metal rod with the offset-
bend and ‘Z-bend’ will be attached to the tail-
wheel’s composite pushrod.
c. Use a high-speed motor tool’s cutoff wheel
to remove the portion of the elevator servo’s
composite pushrod that extends behind the bend
in the metal elevator pushrod.
d. Apply and spread a drop of CA adhesive along the outer surface of the metal pushrod extend-
ing forward where it aligns with the composite elevator pushrod. While the CA adhesive is still
wet, hold the elevator’s composite pushrod next to the metal pushrod and slide the heat-shrink
tubing back toward the tail, covering both pushrods.
e. Confirm masking tape is still holding the elevators in a level position (aligned with the horizon-
tal tailplane). Being careful to shrink evenly but not burn the heat-shrink tubing, apply heat
from an electric soldering iron for a few seconds along the entire length of the tubing.
f. Remove the masking tape from the elevators and horizontal tailplane.
B. AILERONS, WING WIRES, MAIN LANDING GEAR & ELECTRIC POWER SYSTEM:
Although having ailerons on a Blériot XI is not true-to-scale, being able to use ailerons makes
positive control much easier for most pilots. Follow all the steps in this section if you opt to install
the included ailerons for enhanced flight performance and safety. If you are an advanced scale
pilot who values appearance and you are comfortable making slow turns with rudder, elevator
and throttle only, you may fix the ailerons and aileron hatch covers to the wing with transparent
tape, then mount the wing panels, wing wire supports and wing wires to the fuselage as explained
begininning at step 16 on the next page.
1. Use your radio or a servo tester to center your aileron servos. (You may learn about servo testers
at http://www.maxfordusa.com/servo.aspx.)
2. Test-fit your aileron servos to the servo hatch
covers.
3. Prepare each hatch cover’s servo mount to fit
your servos by using epoxy to attach two wooden
servo pedestals to each servo hatch cover as
shown at the right. When the epoxy is cured, use
the hardware provided with your servos to attach
an aileron servo to each hatch cover.
4. Select and install servo arms for your aileron servos that are long enough that servo arm travel
will not be limited and attach an EZ Link connector to the outer hole on each aileron servo’s arm.

5. Use masking tape and a length of coat hanger or
heavier wire to guide each servo’s wire from its
servo bay out through the root rib of each wing
panel. (NOTE: If your servo’s leads do not reach
out fully through the root ribs, add a 6-inch servo
extension.)
6. Use 5/16-inch (1 cm) wood screws to secure the
aileron servo hatch covers to their wing panels.
7. Test-fit the ailerons, CA hinges, 2-pronged aileron control horns
and aileron pushrods to the wing panels.
(NOTE: If necessary, use a sharp hobby knife to ream the outer
holes in the aileron control horns to fit the aileron pushrods and cut
through any excess Mylar covering the CA hinge slots and mounting
holes for the aileron’s control horns.)
8. Center the CA hinges in their slots. Use CA adhesive to attach
permanently the ailerons to their wing panels.
9. Use masking tape to hold the trailing edges of each aileron aligned
evenly with the trailing edge of its wing panel.
10. Slide the straight (unbent) end of each aileron pushrod into the
EZ Link connectors on the aileron servo
output arms.
11. Twist the Z-bend in the aileron pushrods
into the outer holes on the aileron
control horns.
12. Use CA adhesive to secure the aileron
control horns into the holes in the firm
balsa wood in each aileron.
13. Securely tighten the EZ Link connectors onto the aileron pushrods.
14. Leaving at least 1/2-inch of aileron pushrod length in front of each EZ Link connector
to allow for ‘fine-tuning’ of the ailerons, cut off and discard the ends of the aileron pushrods that
extend excessively forward of their EZ Link connectors.
15. Remove the masking tape from the ailerons and wing
panels.
16. Insert and center both wing rods in the fuselage and
slide the wing panels onto their wing rods.
17. If you are using the ailerons, position a 6-inch Y harness
inside the fuselage and, as each wing panel nears the
fuselage, connect the aileron servos (or their extensions)
to the open ends of the Y harness.
(NOTE: We recommend using optional servo safety clips to secure all servo-to-
servo extension and/or Y-harness connections.)
18. Using pliers, attach four springs to four swivels
and four clips as shown at the right.
19. Locate the four composite upper
wing-wire-mounting braces and
four approx. 5/16-inch (1 cm)
screws.
20. Insert the ends of the upper wing-
wire-mounting braces that have the smaller predrilled holes into the four slotted openings in the
top of the fuselage.
