Durafly 1100mm Supermarine
SPITFIRE MK2A
INTRODUCTION:
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".

NOTE:
ecommended BEFORE you begin assembly of the
model. Please refer to ‘Decal application’ on pages 1
illustrated guide on how to apply, and the separate guide for their positions.
ASSEMBLY:
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.

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.

denotes the side that should be connected to the ball joint.
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).

SETTING UP YOUR MODEL:
1. With your receiver installed and all servos plugged into their corresponding channels, connect
the flight battery to the ESC to power up the electronics. With the model now armed, ensure all
servos are centered and all control surfaces are level. If not, adjust by turning the control clevis’s
hand accordingly until the control surfaces are level as shown.
Note: For safety reasons, it is advised that this is done with the prop removed from the
model.

4. Flaps on the Spitfire should be set for 3 stages (up/no flap, mid flap and full flap). Either via your
radio or mechanically by turning the clevis’s on the flap control rod (or via both in most cases), set
mid flap to approximately 40°degrees and full flaps to approximately 87° degrees to the wing. In
the ‘up/no flap’ position ensure the flaps close fully without straining either servo. Also ensure that
both flaps deploy equally at every stage.

DECAL APPLICATION GUIDELINES:
Applying the supplied decals will take you longer than assembling the model. This is because great
care must be taken when doing so. Please follow carefully the guidelines below to achieve the best
possible finish on your Spitfire Mk
Note:
* The decals supplied are vinyl type decals and are supported on a clear adhesives fronting
film. These require care and attention when applying so please follow the below guidelines
and the techniques outlined for the best results.
tudy the
Sep rate the decal you wish to apply (decals are grouped according to their layout on the model)
from the main sheet. The entire decal sheet (including the paper backing) is pre-cut for you so you
can sep
rate each group of decals as required.
.
Before lifting from the paper, rub the surface of the clear protective film/fronting to ensure all of
the decal sticks to it. This will ensure the marking lifts fully off the backing paper intact.
Peel the front off of the sheet ensuring the entire decal lifts with it.
Position the decals/ carefully on the model then gently rub (using a dry cloth) the decal in
place, rubbing from the center of the decal outwards, to avoid wrinkles and air bubbles.
If air bubbles are present, use the tip of a sharp blade to make a small hole in the bubble then rub
over it again to push the air out.
Once the decal is firmly rubbed down and any air bubbles are removed, you can slowly remove
the front clear protective film. DO NOT pull this clear film upwards to remove it, instead pull the
film slowly off to the side. This will ensure the decal doesn’t lift up from the surface of the model
when you remove the clear film. See picture A.
Very gently rub the decal again with a cloth now that the clear film is removed to ensure all edges
are firmly stuck down.

Finally the use of a covering iron is STRONGLY recommended to seal the decals to the painted
foam surface and prevent them from lifting at the edges over time. Set the iron to a low temperature
and gently run the iron lightly over the surface of the decal as illustrated on the following page. Use
of a cloth to cover the head of the iron is recommended to help prevent damage to the foam and the
decal. A household iron can be used if no covering iron is available. See picture B.
