Kavan Der Kleine FALKE Bauanleitung Seite 3

INTRODUCTION
The Der Kleine FALKE (Little Falcon) glider is a great entry level kit for any
modeller who wants to start build on their own; you can assembly it as a
free flight model (meeting the requirements of the F1H alias A1 contest
class). You can also install miniature RC gear and small electric power unit

BEFORE YOU START
Glue: You can use solvent based modeller's glue (UHU® Hart etc.), medi-
um cyano (KAV9952 KAVAN Medium CA etc.) or water resistant white glue
(KAV9960 KAVAN White Glue etc.).
Dope: KAVAN Classic line Protective Dope (KAV9988) and Thinner
(KAV9990) are highly recommended.
Tools and Accessories: You will need a perfectly flat building board
ASSEMBLY
Before you start you should decide which version you are going to build:
Free flight glider: The Der Kleine FALKE conforms to the requirements of
the F1H alias A1 contest class once you add additional ballast in order the
all-up weight was bigger than 220 g.
RC glider: Install a miniature receiver with two 5-6 g micro servos to get a
great little rudder&elevator control glider suitable even as your first RC mo-
del. The all-up weight should be also about 220 g.
Electric powered RC glider: You can easily install a power unit with a
small brushless motor with a pusher propeller installed on a pylon above the
wing. The all-up weight should be in the 300-320 g range.
Wing
1) Carefully sand the entire surface of the wing leading edge halves No.1 and
No.2. Sand the leading edge to the shape shown on the detail in the left
top of the building plan.
2) Glue the wing spar No.3 to the wing leading edge No.1 together on a flat
building board protected with a sheet of thin plastic film. Test fit the
parts together before applying the glue; sand to fit if necessary.
3) Once the glue has cured sand the bottom side of the No.1 and No3 parts
perfectly flat.
4) Support the wing leading edge with a suitable stick and glue the wing
trailing edge part No.4 to it.
5) Once the glue has cured sand the upper side of the wing half smooth.
6) Glue the No.8 stick to the outer end of the wing half. Once the glue has
cured sand it flat to match the wing surface. Build the other wing half
in the same manner.
7) Glue together parts No. 5 and No.6 in order to make the wing joiner.
8) Insert the wing joiner into the notch in the wing; attach the wing halves
together (outer ends supported to create the correct wing dihedral – re-
fer to the picture top left on the building plan) bevel and sand the roots
of the wing halves to match each other perfectly.
9) Once satisfied, glue the wing joiner into one of wing halves; then apply
a generous coat of glue to the other wing half and attach them together
carefully keeping the correct wing dihedral.
10) Glue together both two No.9 parts of the wing outer panels. Sand the
joint smooth and then glue the wing panels to the wing centre section
carefully keeping the correct dihedral.

870 mm
in order to enjoy flying with a small RC glider. You will need some basic
modeller's tools, glues and dopes – you will find these handy with any
of your future projects as well. Please make yourself familiar with the
building plans and this manual BEFORE you actually start the assembly.
All-up Weight
(at least 150x700 mm) , modeller's knife (Excel K1 w. No.11 blades etc.),
razor saw, builder's triangle, electric drill with 1.5, 2.5 and 5.5 mm drill
bits, sanding blocks/sponges with 180-200 and 360-400 grit sandpaper,
needle files, model hobby pins (KAV0355 Modeller's Pins), soft flat (1/4"-
3/8") brush, thin clear plastic film to protect the building plan/building
board (a large PE bag cut open will work).
11) Glue the wing trailing edge reinforcement plate No.7 in place.
12) Apply a light coat of thinned protective dope to the entire wing. When
dry, lightly sand all doped surfaces with the fine sandpaper. Repeat
twice more; sand lightly once every coat has dried. Apply the stickers.
Fuselage and Tail
1) Glue the fuselage formers No. 18-22 square to the fuselage base plate
No.10.
2) Glue the No.34 upper longerons to the formers.
3) Glue the nose plates No.11-13 one by one in place.
4) Glue the rear plates No.28-33 one by one in place.
5) Glue the No.41 lower longerons to in place.
6) Sand the both sides of the fuselage smooth.
7) Glue the No.23 fuselage side plates in place.
8) Glue the No.14 upper plate in place. CAUTION: Apply the glue ONLY in the
front on the top of the No.13 nose plate and ONLY tack glue the No.14
plate in the rear (along the No.20 former).
9) Glue the No.15-17 upper plates in place.
10) Cut and sand smooth the fuselage in order to create nice smooth curves.
11) Drill through the openings for the wing fixing dowels using 2.5 mm drill
bit. Glue the dowels in place.
12) Use a fine razor saw to cut through the No. 15 and No.14 plates in the
laser scribed line in the nose. Remove the canopy carefully and glue the
No.27 alignment pin along the front edge of the No.14 plate. The No.27
pin overlaps the front edge of the No.14 plate securing the front of the
canopy in place.
13) Bind the wing to the fuselage using supplied rubber bands. Now sand
the rear bottom part of the canopy to match the curve of the wing.
14) Glue the No. 24 inner towhook plate to the bottom of the fuselage; take
care the pre-cut hole was in the longitudinal axis of the fuselage. Drill
through the hole using 1.5 mm drill bit; glue the No. 25 lower towhook
plate concentric to the hole in place.
15) Apply a light coat of thinned protective dope to the entire fuselage.
When dry, lightly sand all doped surfaces with the fine sandpaper. Re-
peat twice more; sand lightly once every coat has dried.
16) Drill through the hole for the tubular tail boom using 5.5 mm drill bit in
the rear end of the fuselage.
