9. Operating the Model

a) Inserting and Connecting the Flight Battery
The flight battery is inserted into the fuselage in the area before the wing plug after the canopy is removed and attached with hook-and-loop tapes. The precise
position of the rechargeable battery is determined by the centre of gravity.
Ensure that the battery is sufficiently attached so that it will not come loose during aerobatics or 3D-flight and cause damage and/or to prevent the
model from becoming uncontrollable and crashing because the centre of gravity shifts considerably.

b) Setting the Centre of Gravity

The flight battery must be installed in the battery chute with hoop-and-
loop tape so that the centre of gravity is approx. 30 to 33% behind the
leading edge of the wing.
To do so, mark the corresponding centre of gravity position on the ribs
of the wing.
From the bottom, hold the assembled and ready-to-fly model at the
measured positions with your index fingers (or a corresponding device).
If the centre of gravity is set correctly, the model should be leaning
slightly forward.
Important!
Always measure the centre of gravity with the canopy in
place.
For the first flights, set the centre of gravity at approx.
30% wing depth.
The best centre of gravity then can be perfectly set slowly.
Practical advice:
When you have determined the centre of gravity, mark the flight battery
and the fuselage, e.g. with a non-water-soluble felt pen). Thus, when
you change the flight battery, you do not have to determine the centre
of gravity again.

c) Setting the Rudder Deflections

When the construction is performed correctly and the transmitter set, the rudders should have the following deflection values. The values in brackets are
recommended for 3D-flight.
Aileron 20° (40°) upwards
Elevator 15° (40°) upwards
Side rudder 25° (45°) left
Attention!
The indicated values show the lower and the upper thresholds of the rudder deflections. Adjust the deflections individually to suit your personal
preferences.
Use a computer remote control for your model to comfortably set the values from the transmitter.
If you are using a normal remote control, the values are set by repositioning the push rods on the servo arms or the flaps.
20° (40°) downwards
15° (40°) downwards
25° (45°) right
