Balancing the BO 209 MONSUN
The completely equipped model, with the fuel tank empty, should balance level when
supported at a point about 100 - 110 mm aft of the leading edge of the wing, ideally
in inverted flight position. If the centre of gravity is correct, the model should balance
out horizontally or with the nose pointing slightly downward. If necessary, adjust the
centre of gravity by shifting the position of the receiver batteries. Before flying the
aircraft, set the transmitter trims to centre and ensure that all the control surfaces are
also exactly centred (in neutral position).
Rudder deflection for normal flying
Ailerons
35 mm up and 15 mm down
Elevators
25 mm up and down
Rudder
75 mm left and right
Landing flaps
Take-off
15 mm down
Landing
60 mm down
We recommend that you set exponential values of 30% at the transmitter.
Important:
When assembling the rods, always take care to ensure that they move freely and can
move through their entire controllable path - including trim travel - and are not
mechanically impeded.
When the joystick moves to the right, the rudder must turn to the right (left stick/left
rudder). When the elevator stick is pulled back, toward your stomach, the elevators
must deflect upward (stick forward = elevators down). If the aileron stick is moved to
the right, the right aileron should move upward; the left aileron downward. When the
throttle stick is pushed forward, the motor must run at full power; if the throttle stick
and trim are moved back to their end-points, the engine must stop. If the trim travel is
moved all the way back, the motor must stop. The landing flaps are best activated via
a three-position switch.
All that remains is to wish you many hours of happy flying with your BO 209
MONSUN.

Safety notes and warnings
Regarding motorized aircraft models with internal combustion engines
•
Before you first attempt to fly the model, it is essential to carefully read all
the operating and assembly instructions.
•
These safety notes are part of these instructions and must be stored
carefully with the operating instructions and, if the model is passed on to
others, they must also be passed on to the next user.
