hinge braciets. Check that the rudder is tree to move, and that it can
delLct to the throws stated on the plan on either side. ll it binds up, sand
back the rudder leading edge, or pull the hinge brackets out ol the fin
slightly. wllen the rudder is rotated, the gap between the rudder leading
edöe änd the fin sides should be no greater than 1.5 m m However' the
rudler must on noaccount rub on thelin sides. Checkalignmentand free-
dom ot movementagain, then pullout the hingetube. Caretult remove the
rudder, taking care not to alterthe position ot the hinge brackets, and glue
the brackets into the stem post, using instant glue.The steelrod forrudder

ihe rudderand markthe position ofthe rudderhom onthe rudder' File out
a slot in the rudderto take the hom. Notethe position ofthe hom, as shown
on the plan. The point at which the pushrod engages must be alignedwith
the rudder hinge line. The distance from the hinge line to the rudder
pushrod engagement point should be 12 m.m. The horn itself is not glued
into ptace until the rudder has been covered.
The next steo is to set u D lh e elevator. Press the hollow rivet into the hole in
the tailplane, and fixthetailplane tothefin, using plastic screw 21. Measure
the distance trom each tallplane tip to the centre of lhe fuselage nose; it
must be the same on each side. Draw round the top of the lin on the tail-
plane support, and unscrew lhe tailplane. Orive in a selt-tapping screw
(2.2x6.5 m.m.) where marked on the tailplane seat 19. Measurethe €xact
location ofthe screw head on the tailplane, andtranslerthe position to the

place again, and recheck that it is aligned squarely. lf necessary, file out
the hole lorthe hollow rivet. when satisfied, glue the hollow rivet in place
with s-minute epory. Whilethe resin issetting, screwthetailplane ontothe
fin and check that it is still aligned conectly.

surface with the fin exactly upright. Measure the distance from the table
surtaca to the centreline otthe tailplane leading edge and the centreline ot
the trailing edge spar, at the root ol the tailplane. To do this, mark the
centrelines on the tailplanewith a pencil The distance from the table to the
leading edge centreline mustthen be 342 m m.,and the distance from the
table to the trailing edge centreline must be 335 m.m. Please measure
these dimensions very carefully, as theflight performance ofthe ASW 22
deDends to a considerable extent on the conect incidence setting. lf
necessary, trim backthe tailplane seat. Screw the tailplane tothefin, and
add any small hardwood wedges underthe tailplane untilthe dimensions
are conect. Gluethese piecestothetailplane seat. Now cover the tailplane
seat with sellotape, and apply a th in coat af wax or oil to it to act as a r€lease
agent. Cut out holes in the tape for the plastic screw and the locating
screw. Mix up a polyesterfiller paste and apply it to the plywood tailplane
support on thetailplane. Screwthetailplaneto the fin, and wipe olf excess
filler oaste. Let the filler harden and then unscrewthe tailplane. Sand the
filler smooth.

Pass a 1.3 m.m. O, 1250 m.m. long steel pushrod into the wing-mounted

Pullthe end otthe steel rod out of the wing slightly, and solder a thr€aded
muoleronto the end, alter roughening up and bendingthewire slightly, as
described before. Screw a metal quicklink onto the coupler, and lock it on
the threads with adrop otglue. Connectthequicklinktothe bellcrank, and
fit the bellcrank support plate into th€ wing. Check that the crank works
properly, and remove small amounts of loam to avoid any tendency to jam
u o. ThJbellcrank and its push rod musl not come into contact with foam at
any point. When working on the starboard wing, please not€ that the bo!'-
den cable outer sleeve must end about

not the csse, tullout the steel pushrod and twist a smallround needlefile
into the outer. Release the outerlrom the sheeting by gentlytwisting itto

Check the linkage lor corect operation, and bend the threaded pushrod
slightly if necessary until all is in order. Temporarily fit the aileron to the
wing, using strips of sellotape, and mark the position ol the aileron hom
from the exit ooint of the th readed pushrod. File a slot in each aileron, sand

oI the homs must be identical on both ailerons, to ensure equal aileron

aileron hinge axis. Set the bellcrank and aileron to neutral and bend the

The ASW 22 wing panels are factory-prepared forthe installation of aiöra-
kes. The aiörakes units (Order No.72 2641) are notsupplied inthe kit' but
we strongly recommend that you fit them as a means of controlling the
glide angle on the landing appoach They make it possibl€ to land sately
;ithout great ditficulty even in confined spaces. We urge you strongly not
to omit the airbrakes. lf, however, you decide against fitting th€m, then the
ore-cutairbrakew€llhasto be sealed. To dothis glue in-flllstrip 63 intothe
slot. Run a line ot ißtant glue round the d ie-cut aiörake capoulline in part
64, and glue thls piece into the wing sand flush with the wing when dry'

Cut steel Dushrod 61 (0 8 m.m. O) in half, and slide one rod from th€ rcot
end ol the wing into th€ airbrake bowden cable out€r as far as the aiÖrake
well. Here again - as described in the aileron installation section
- a little
foam will need to be removed. Bend the rod asshown on the plan, and con-
nect it to the aiörake actuation lever. Fittheaiörake unit intothe aiörake
well.The unitshould be an easyslidingfit.Itnecessary,
sand backthe foam
insid€ the well, using a flat sänding sticK until the unit can be fitt€d with
light finger pressure. Do not use lorce, asthis willpress the aiörakssides
iriward, and Sop it lunctioning. lt may b€ necessary to bend the aiörake
end of the pushrDd slightly, as manufactuting tolerances preclude dead
accurate fitting otthe outertube in the wing. Checkthatthe unitfunctions
freely, and re;ove it ftom the wing. Beloregluingthe airbrake unitintothe
wing, it is essentialto cany oul one smalljob, which guarantees thatthe
aiörake will work taultlessly; seal otf the outside ends ol the aiörake pivot
shafts with smallpiecesofsellotap€, so that it i8 not possiblelorgluetojam
them up. Glue the aibrake unit into the wing, using 5-minute epory, and
checkthe unit for conect operation now and thenwhileths glue is setting'
Glue the sealing strip 64 in ptace, with the dle-cut side uppermost' and
carefully separate thedie-cut portion with a shatp balsa knlle The separa-
ted strip is then glued to the top of the aiörake with contact cemer , and
the balsa parts sanded backflush with thewings. Checkagain thattheair-
brake works conectly, and trim the balsa strips as nece$ary to provide
clearance. In the case of the staöoard wing panel, the aiörake bowd€n
cable outer sleeve must be rece$ed 15 m.m. insidethe wing, as with the
aileron ouler. Pull it oul, cut it short, and push it back insidethewing The
wing joiner blade 67, locating pin 68 and root rib 69 are fitted at a later stage
of construction.
