Caution: this model is not a toy!
If you are a beginner to this type of powered model, please ask an experienced
model flyer for help and support. If you attempt to operate the aeroplane without
knowing what you are doing, you could easily injure yourself or somebody else.
Please keep your safety and well-being in mind at all times.
Important: before you start construction
Even if you have already built a large number of RC models please read right through
these instructions and check that all the kit components are actually present. We
have taken great trouble to keep construction as simple as possible, without making
any compromises in the area of safety.
Check that the radio control system is working correctly and at full range before every
flight: check that all the control surfaces work smoothly and immediately at an
appropriate distance, and deflect in the correct ‘sense’ (direction) relative to the stick
movements.
If you are a relative beginner to model flying, we recommend that you enlist the aid of
an experienced model pilot to help you check and test-fly the model.
The receiving system components and control linkages must be installed at the
appropriate stage of construction, as it may be very difficult or even impossible to install them later.
When you are buying a radio control system it is important to ensure that the transmitter and receiving system are designed for use with model aircraft, and are approved by your national Post Office approvals authority. All RC units should possess
an FTZ series approval number.
Please remember that other radio systems and radio-frequency apparatus are also
permitted to operate in the frequency ranges used by model radio control equipment,
and there is no guarantee that your system will not suffer interference caused by
such apparatus.
If you are not sure whether this applies to you, contact your nearest Post Office
Telecommunications office. Your local model shop will also have this information.
Note regarding the film covering
Minor creases or bubbles may develop in the film covering due to major fluctuations
in weather conditions (temperature, humidity etc.); in rare cases you may even find a
slight warp in a component. These minor faults are in the nature of film-covered builtup wooden structures, and can easily be corrected using a heat gun, as commonly
used for modelling.

Creases: Blow warm air over the area and rub down with a soft cloth.
Wing warp: Hold the panel twisted gently in the opposite direction to the warp, and
apply warm air to remove the creases from the covering.
Caution! do not heat the film more than is absolutely necessary. If the air or the
iron is too hot, the film may melt and holes may be formed.
This aeroplane is highly pre-fabricated and can be built in a very short time.
However, the work which you have to carry out is important and must be done
carefully. The model will only be strong and fly well if you complete your tasks
competently - so please work slowly and accurately.
When self-tapping screws have to be screwed into wood, apply a little white
glue to prevent them shaking loose: just squirt white glue into the hole before
fitting the screw.

Radio control system
The RC system must feature at least four channels and five servos. The transmitter should also include a servo reverse facility.
We particularly recommend MX-12 to mc-24 computer systems. Standard-sized servos are required for rudder, elevator and throttle.
For the ailerons the model needs servos with a case width of 13 mm.
We recommend the following receiver power supply: LiPo 2/1600, Order No. 9717.2,
in conjunction with the PRX 3A ON / OFF switch, Order No. 4135; these batteries
need to be maintained carefully before and after each flying session.
For more information please refer to the instructions supplied with your RC system,
rechargeable batteries, etc.

For connecting the aileron servos to the receiver you will need two extension leads
180 mm and 320 mm long; foam rubber is also required for packing the receiver and
battery, e.g. foam rubber, Order No. 1637.
Adhesives
White glue, e.g. UHU coll, Order No. 958.60
UHU hart, e.g. Order No. 534.35
Cyano-acrylate (“cyano”), e.g. Order No. 5822
Thread-lock fluid, e.g. Order No. 952
Accessories required for the glow-engined version (not included)
Fuel based on synthetic oil, to suit engine
Fuel filter, e.g. Order No. 1650.1
Fuel tubing, e.g. Order No. 1643
Manual fuel pump, e.g. Order No. 1610
Glowplug energizer battery with plug clip, e.g. Order No. 3248
Electric starter, e.g. Order No. 1628
Starter battery, e.g. Order No. 2592
Accessories required for the electric-powered version (see table)
Battery chargers: see main FS catalogue
Tools required (not included)
Set of cross-point screwdrivers, flat-nose pliers, side-cutters, balsa knife or razor
blade, set of twist drills, universal glowplug spanner, soldering iron, set of allen keys.
Please don’t start assembling the model until you have checked the kit components
and the building instructions, and are familiar with the construction procedure. If you
are not happy with any component, kindly return it to your model shop without delay,
before you have modified it in any way.
Assembling the LANCAIR
The wing panels
Remove one arm from the servo output levers, as shown in the photo. Set the servos
to centre from the transmitter, and fit the output levers on the servo output shafts.

Set the servos to centre from the transmitter. The wing-mounted servos are attached
to the support blocks using the retaining screws supplied with them: the first step is to
push the rubber grommets into the servo mounting lugs, followed by the brass tubular
spacers, with the flange on the underside. The spacers are easier to fit if you slip
them on a suitable screwdriver first. Drill 1.5 mm Ø pilot-holes in the support blocks,
using the metal spacers as a guide, then fit the servo retaining screws as shown.
The servo leads can now be pulled through the wing panels using a length of thread:
tie the thread to the servo lead just behind the connector, then pull it through until it
appears at the root rib.
Fit the servo mounts in the wings and secure them with the retaining screws supplied.
Mark a centreline on all the aileron hinges using a pencil, as shown in the photo.

The hinges can now be inserted in the ailerons as far as the pencil lines, and glued in
place using cyano; a syringe needle works well as a nozzle.
When the glue has set hard, insert the projecting hinges into the slots in the wings
and glue them in place with cyano. Note that there should be a gap about 0.5 mm
wide at the hinge line.
Shorten the GRP horns to the point where only the bottom linkage hole remains.
Use the tip of a hot soldering iron to remove the covering film over the horn slots, and
glue the horns in them using UHU plus (epoxy).
Ensure that the clevis linkage holes are exactly in line with the hinge pivot axis.
The aileron pushrods can be assembled when the glue has set hard. Adjust the
pushrod length so that the aileron is central when the servo is at neutral.

The two clear lamp covers can now be trimmed to size and glued to the wingtips.
Cyano or UHU ALLESKLEBER Kraft can be used as adhesive.
To hold the two wing panels against the fuselage a retaining bolt has to be screwed
into each wing root rib. Apply UHU thread-lock fluid to the threaded part, and screw
the bolts into the sockets as far as they will go.
Installing the undercarriage
Locate the screw-holes in the undercarriage legs and mark their position on the
wheel spats, as shown in the photo; you may need to chamfer the edges of the wheel
legs slightly so that they rest flush in the wheel spat recesses.

The wheels and the wheel axles can now be attached, as described below:
The first step is to fit the wheel and collets on the axle; the collets are used to centre
the wheels in the wheel spats. Apply a drop of UHU thread-lock fluid to the grubscrews and nuts to prevent them working loose.
Use the tip of a hot soldering iron to melt the film over the screw-holes and undercarriage mountings. Fix the undercarriage units to the fuselage using the socket-head
cap screws supplied in the accessory pack.
Prepare the noseleg yoke as shown in the photo: dismantle the yoke, then reassemble it with the wheel spat in the proper location.
The yoke must be aligned with the wheel spat before the socket-head cap screw is
finally tightened: this can be checked with a setsquare.
