• Bevel the root ribs of the wing outer panels using
the supplied 7° dihedral jig. Trial fit the carbon wing
joiner into the respective bays; there should be a ti-
ght fit, no play. If there is a significant play, put some
epoxy to appropriate area of the joiner and sand as
necessary once the glue hardens. (Fig. 42+43)
• Glue the 3 mm liteply root ribs with 3 mm beech
alignment pins. (Fig. 44+45)
• Prepare everything for the airbrake servo installati-
on; glue the fibreglass plate to the lower surface of
the airbrake and the liteply magnet holder to the rear
of the servo bay. (Fig. 46)
• The spoiler servo is to be installed using a balsa spa-
cer (not supplied in the kit) - depending on the di-
mensions of your servo. The spacer + servo must not
be higher than the wing ribs; it may not obstruct the
spoiler when closed (do not forget to take in account
the double sided foam tape you will use to secure the
servo!). Apply epoxy or medium cyano to the servo
spacer (if used) and the entire balsa lower sheeting
of the servo bay in order to be sure the double sided
foam tape will stick.
Covering
• Thoroughly sand the surface of all parts with No.
360-400 sandpaper and carefully vacuum all the dust
(the iron-on film does not stick well to a dusty sur-
face; the dust also contains hard grains released off
the sandpaper capable to ruin the smooth coating of
your sealing iron quickly).
• Use as light iron-on film as you can get (transparent
Oracover, Oralite etc. – not supplied in the kit). Follow
the instruction manual supplied with the covering
film of your choice please.
Hinging the Control Surfaces
Use strips of a high quality hinging tape (available in
hobby shops) or strips of the same iron-on film you
used for the covering. Remember to apply the tape
with the control surface deflected to the limit in order
to get free movement of the particular control surface.
Tail Surfaces and Tail Boom Installation
• Attach the wing centre section to the fuselage and
the horizontal tailplane to the tail boom; secure them
with nylon bolts. Slide the carbon fairing and the ply
fairing former onto the carbon tube tail boom. Insert
the tail boom into the fuselage (no glue yet). Check
again that the fuselage is straight; align the wing and
the tailplane with their trailing edges parallel. Once
satisfied, epoxy the tail boom and the carbon fai-
ring with its former to the fuselage. Before the glue
hardens double check the correct alignment of the
wing, fuselage and tailplane.
• Use medium CA to glue the fin into the tail boom; be
sure it is square to the horizontal tailplane.
Pushrod Installation (Fig. 47)
• Tack glue the pushrod tubes to the 1.5 mm balsa
pushrod tube holder.
• Tack thick cyano to the balsa and insert the pushrod
tubes into the carbon fuselage tube (with a little help
of pushrod strings).
• Insert the pushrod strings into the respective tubes
from the tail end.
Servo Installation
Rudder and Elevator Servos Installation (Fig. 48)
• Make a „Z" bend on the end of the pushrod and fit it
to the servo horn.
• Alternatively you can use a closed loop of a Kevlar thre-
ad (not supplied in the kit) to hook the rudder – it might
save some weight. In that case you will need to install
just one pushrod for the elevator.
Spoiler Servo Installation (Fig. 49)
• The spoiler servo is to be installed using a balsa spa-
cer (not supplied in the kit). The thickness of the spa-
cer depends on the dimensions of your servo. The
spacer + servo must not be higher than the wing ribs
(in may not obstruct the spoiler when closed).
• Glue the fibreglass plate to the spoiler.
• Glue the magnets to the spoiler and wing using the
supplied liteply holder.
• Please check the polarity of magnets first – they must
attract each other.
Pushrods and Towhook (Fig. 50)
• The pushrod tubes are to be located over the liteply
plate.
• Thread them through the holes in the former next to
servos.
• Install the towhook to the pre-drilled holes.
Wing Root Rib (Fig. 51)
• Glue the magnets using 5min epoxy.
Pushrod Installation – The Tail End (Fig. 52)
• Trial fit the rudder and elevator horns (no glue yet),
bend the ends of pushrod strings to the „L" shape and
thread them through the hole in the horn. Once sa-
tisfied, cyano the horns into the rudder and elevator.
• Please note the servo arms have to be square to the
pushrods in the neutral.
• Glue the end of the rudder pushrod tube to the fuse-
lage.
• The end of the elevator pushrod tube remains free, no
glue here.
Towhook (Glider Version) (Fig. 53)
• Keep the recommender CG position 78 – 82 mm be-
hind the wing leading edge.
• Set the towhook 10 mm in front the CG for the first
flight.
• You have to loose the front screw in order to move
the towhook.
Power System Installation (Electric Version)
(Fig. 54-56)
• Fit your motor using appropriate screws to the fi-
