The Supermarine Spitfire is THE defining aircraft of WW2, the Mk2a was one of the early versions
that defined this incredible airplane. The Mk2a was equipped with the new Merlin XII engine and
either a De Havilland or Rotol propeller which together produced an extra 120hp over the the
Mk1a set-up. During the darkest days of the war, the Spitfire, more than any other aircraft then or
since, along with the pilots that flew it, came to symbolize the struggle and triumph of a nation
over adversity. This struggle was the "Battle of Britain", those pilots were "The Few" and the
triumph was the Spitfire!
Durafly’s Mk2a Spitfire P7308 represents a Spitfire that was flown by Squadron No 71, this was
one of the Eagle Squadrons that were formed in the early days of WWII. These fighter squadrons
were formed using volunteer pilots from the United States prior to America's entry into the war in
December 1941. Spitfire P7308 is now operated under the care of "The Fighter Collection" based
at Duxford in England, and its other claim to fame is that it flew in the making of the 1969 film
"Battle of Britian". The attention to detail in this PNF model is matched only by its superb
performance and grace in the air. The Mk2a is designed purely for a 4S set-up unlike previous
marque's, but it still boasts a range of features you have come to expect from Durafly. These
features include, retractable landing gear, faithfully reproduced split flaps, scale outline, fine
surface detail and finish, LED lighting system, and authentic scale decals.
Very simply, you will not find a better rendition of a Spitfire Mk2a at this scale from anyone other
than Durafly. It will appeal to both British and American model airplane pilots for its tribute of a
Spitfire flown by one of the extrordinary Eagle Squadrons that were formed using eager, young
Americans, who wanted to help make a difference, particularly during the "Battle of Britain".

REQUIRED TO COMPLETE MODEL:
1. Main wing.
2. Fuselage.
3. Horizontal Stabilizer/Spar
4. Wing Radiators
5. Scale Plastic Parts
6. Control Accessories/Hardware.
7. Prop/Spinner.
8. Decal Sheet.
In its ‘Plug n Fly’ format the Spitfire Mk will still require some additional electronic components
to get it ‘flight ready’. Durafly recommends the products below for optimum performance and
great value. Available at

ecommended BEFORE you begin assembly of the
model. Please refer to ‘Decal application’ on pages 1 - of this manual for
illustrated guide on how to apply, and the separate guide for their positions.
1. Out of the box your Spitfire comes with reinforced foam hinges. However before assembly can
begin, each hinge line must be flexed back and forth 5-6 times to reduce tension and load on the
servo. Do this for all control surfaces before continuing.

1.7x6mm
2. Insert one half of the carbon tail spar into one of the horizontal tail pieces before sliding this half
into the tail slot of the fuselage. Now install the remaining tail piece (A). Secure both halves in
place with the supplied 2.3x6mm screws (B) and the elevator join with the single 1.7x6mm screw
(C). This installation is self aligning, but do double check to ensure equal alignment to the vertical
tail and wing.

3. Using a pair of pliers (ball link pliers preferably) connect the elevator push rod to the elevator
control horn (A). To ensure both the elevator and rudder are neutral (with the servos centered)
loosen the grub screw of the piano wire fastener until both surfaces and slide the push rods until
both are neutral if required (B). The steerable tail wheel can be adjusted the same way (C).
Tighten all firmly when done.
4. With the aileron control horns at 90 degrees to the wing surface (neutral) insert the aileron
push rod into the top hole of the control horn. Secure in place with the plastic keeper and then
connect the ball link to the ball join using pliers (A). Repeat this same process for the flaps, the
exception being that the flap servo horns must be positioned as far rearwards as possible.
This will give a flap neutral position with the push rods connected (B).
B.
Note: Each ball link has a faint circle molded on one side.This
denotes the side that should be connected to the ball joint.

Note: It is recommended that you balance the prop and spinner before
installing for optimum performance and efficiency.
5. Offer the wing up to the fuselage and ensure the servo wires pass through into the battery area
of the fuselage (A). Check again that no servo wires are caught between the wing and fuselage
before securing in place using the four 3x10mm bolts supplied (B)
6. Slide the spinner back plate onto the motor shaft making sure the ‘hex’ shape opening at the
rear of the plate fits over the ‘hex’ on the base of the shaft. This is followed by the prop and prop
nut. Tighten the prop nut then finally screw the spinner in place.
7. With a small amount of contact glue, secure the under wing radiator in place
along with the cockpit mirror ( and ).

the fish tail exhaust stacks onto the fuselage.
9. Install you choice of 6 channel receiver (Orange X620 shown) in approximately the area shown
below. Ensure all wires are held away from the servo horns. Also shown is the exact location of
a 40C 2200mah 4S lipo (as far forwards as possible) to achieve the correct CG as detailed in the
following pages.

Congratulations, basic assembly of your Spitfire
Mk2a is now complete. Please perform a final
check on all screws, bolts and components,
ensuring all are secure and firmly in place.
