Motor Commissioning

a) Setting the Centre of Gravity

The model must be adjusted by suitable place-
ment of the receiver and/or flight battery, (and
if required by adding lead trimming weights), so
that the centre of gravity is located approx. 110
mm behind the leading edge of the wing.
To do so, mark the corresponding centre of gra-
vity position on the ribs of the wing.
Use your index fingers (or a device intended
for this) to hold the assembled and ready-to-fly
model from below at the measured positions.
If the centre of gravity is set correctly, the model
should be leaning slightly forward.
Important!
For the first flights, set the centre of gravity at approx. 100 mm wing depth. The best centre of gravity then
can be reset slowly.

b) Setting the Rudder Deflections

When the construction is performed correctly and the transmitter set, the rudders should have the following deflection
values.
Aileron
Elevator rudder
Rudder
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.
