INTRODUCTION
The Spitfire MK IX from AVIATION DESIGN is a scale model with excellent flying and ground handling
characteristics.
The Spitfire is one of the most famous warbird, and probably the best design with its elliptical wing.
Our model is 100% scale and had already made several F4C competition.
The model is fully molded in epoxy/glass with all panel lines engraved and all rivets and screws in relief.
Construction is very straightforward and requires only approximately 15 hours for assembly.
The model is designed to be fitted with a large Spring Air retracts. This model has plug in wings.
The large engine bay accommodate 2-strokes engines from 20-32cc and 4-strokes from 20-30cc.
The performance are really fantastic !
This warbird is very easy to fly. Our Spitfire has some incredible low speed performances due to its special
wing section and washout. Some aerobatics manoeuvres are also possible.
This model has plug in wings. The kit is designed for Spring Air retracts

CONSTRUCTION
WINGS
According to the drawing under the wings,
cut the gear location with a small cutting disc
(Perma Grit disc for ex.).
Remove the fiber+foam for the wheel
location.
Install the servo in the wings.
Make a 3 mm slot in the aileron and glue the
control horns..
Insert in the wing the servo extension lead
Make a hole in the wing root for the servo
lead.
Connect the servo and
the control horn with 2 x
M3 links and M3
threaded rod.
Apply thread lock.
Screw the wing hook in
the wing root chord

Slide the aluminium tube in the fuselage.
Slide the 2 wings against the fuselage.
.
Landing gear :
Fit the 2 landing gears in the wings
Drill 8 hole diameter 1 mm and screw the 8 parker
screws
Connect all air tubing.
You can use the mecanic air valve with a micro servo or
use an electovalve (optionnal).
The air bottle will be fitted in the fuselage with double
face tape.
A quick air connector will allow to disassemble the
wings
Fit the oleo legs in the spring air retracts.
Fit the wheels on the legs.
STABS
Horizontal stabilizer and stabs Control surface :
Drill some 5 mm hole in the control surface leading edge and
trailing edge stab for the hinges location.
Sand the trailing edge with half round Perma Grit tool
Glue the hinges with epoxy
The hinges should be pinned.
Make a 3 mm slot in the aileron and glue the control horns..

Fin Control surface :
Drill some 5 mm hole in the control surface leading
edge and trailing edge rudder for the hinges location.
Sand the trailing edge with half round Perma Grit tool
Glue the hinges with epoxy
The hinges should be pinned.
Make a 3 mm slot in the aileron and glue the control
horns..

FUSELAGE
Tail wheel :
Glue C6 in the fuselage
Fit the tail wheel on C6.
Servos
Fit the 2 servos on the plywood support.
Make sure that the servos do not touch the
fuselage.
Glue C5 in the fuselage with epoxy and fiber
glass.
Connect the rudder servo to the control horn
with 70 cm M3 threaded rod and 2xM3 link.
Glue the obechi spar on the M3 threaded rod
For the elevator servo, weld the rod in Y as
drawn
Connect the elevator servo to the control horn
with 70 cm M3 threaded rod .
Glue the obechi spar on the M3 threaded rod
Fit this in the fuselage and screw the M3 link.
Engine :
The large engine bay accommodate 2-strokes
engines from 20-32cc and 4-strokes from 20-30cc.
Thunder Tiger 120, Super Tiger 2500, MOKI 180..
Anti-torque should be 1.5 °
The engine can be installed with 4 threated rods
direct on the plywood support like on our prototype
(see pics and drawings).
It can also be fitted on a normal engine mount.

Throttle :
Screw the servo behind the front plywood frame
Connect the servo to the carburator with M3 link.
Tank :
Install the fuel tank in the fuselage with foam
.

Cowl fixation :
Drill 6x 1mm diameter hole in the cowl and screw the 3 Parker screws.
Drill a hole for the plug and for the needle valve.
Draw on the cowl the cooling hole according to the plan and pics
Cut a hole in the cowl for the air cooling of the engine.
Draw on the cowl the exhaust pipes location
Cut 12 holes in the cowl for each pipe to extract the hot air from the cooling .
Glue the 12 pipes on the cowl with CA
CANOPY
The canopy will be fitted with parker screws.
FINISHING TIPS
Now you have to remove the wax from the model.
The best way to do this is to sand all the fuselage with a "scotch brit" scouring pad used to wash up the
crockery
Do not apply primer on the model.

All parts must be directly painted.
Think light : excessive paint build-up will add unnecessary weight to the model. Apply light, thin coats of
paint and sand between coats to avoid excess weight.
For the stabs and fin, finish them as light as possible to have no trouble with the CG.
RADIO
The Spitfire needs 5 servos :
Ailerons : 2 servos 3 kg torque (ex : S3002)
Elevator : 1 servo 4 kg torque (ex : S3002)
Rudder : 1 servo 4 kg torque (ex : S3002)
Throttle : 1 servo 3 kg torque (ex : S 148)
You normally need a 1200 Mah battery power.
The correct CG is just of the corner of the wing root.
Note : balance the model with fuel tank empty.
Aileron travel : 13 mm up and 13 mm down
Elevator travel : 15 mm up and 15 mm down
Rudder travel : 30 mm left and 30 mm right
It will be necessary to have a downward elevator trim ( - 4 mm)
The total weight of the Spitfire is 7.5 to 8.5 kg tank empty.
Cockpit detail kit : ADW 209
Paint the instrument panel in black

All the vaccum parts will be painted in green
Glue the instrument panel on the vaccum part
Fit this part in the fuselage. Don’t glue it but screw it on wood block to have access to the fuel tank.

Detail set : ADW 207
Cut the exhaust pipe in 12 parts : lenght 40 mm, 45° angle.
Glue them on the cowl according to the plan.
Cut the under wing fairings (front face and rear face) so that the air can pass through them (to reduce the
drag). Glue them with cyano according to the photo and engaved line
Important note :Pay very careful attention to structural integrity. It is your responsibility to
operate it safely.
Specifications may change without notice.
