Recommended Radio Equipment
• lightweight receiver: Graupner GR-12S, Spektrum AR6310,
FrSky VD5M, TFR4 (Fasst) etc.
• 3x micro servo 2,5 – 3,5 g: Graupner DS 101, Dymond D2.7,
PZ-15318 etc.
• one cell LiPo ca. 150 mAh
Balsa tail surfaces are protected against humidity with clearcoat.
The wing may be removable or xed. If you do not require removable
wing, exclude steps marked with a yellow point and glue the wing
to the fuselage with epoxy. Before glue hardens, carefully check the
perpendicularity to the fuselage.
Grind all gluing spots thoroughly, before you apply the glue!
Mark, drill and countersunk
Ø 2 mm holes for the wing
screws.
Cut slots for the aileron arms and
glue arms with foam friendly CA
or epoxy.
Complete wing-mount. Then insert it into the fuselage and screw the
wing. Check if the wing is perpendicular to the fuselage and carefully
glue wing-mount with thin CA.

Trim elevator pylon height and glue elevator to pylon with thin CA.
Then check elevator alignment to the wing and glue pylon to the
fuselage with thin CA.
Put rudder to the fuselage, check if the perpendicular to the elevator
and in the axis of the fuselage and glue it with medium CA.

Before you glue the servo board into fuselage, carefully check the
function of the RC system and set up neutrals of all servos. Then glue
it with thick CA.
Complete aileron pushrods, connect wires to the servo arms
with Z-bends and to ailerons horns with simply bends, check free
movements and neutrals of ailerons and glue pushrods to the
fuselage using medium CA.
Connect the elevator horn to servo arm with attached wire leader.
Install receiver and battery in the fuselage and check the center of
gravity. Program the transmitter and fly!
Recommend initial settings
Centre of gravity ....................................................42 mm from leading edge
Ailerons deflection............................................................ up and down 5 mm
Elevator deflection............................................... 3 mm up and 5 mm down
Brake ............................... ailerons 15 mm down and elevator 2 mm down
