If you push the left-hand control stick on the transmitter unit to the right (fig. 2, pos. 10), the side rudder flap (1) must extend some 2.5 cm to the right.
Figure 10d
The rudder extension can be accurately adjusted depending on which drill-hole on the rudder clamp the clevis is inserted into. If the clevis is attached closer to
the fulcrum of the rudder, the rudder extension will be increased. If the clevis is attached further out, the extension of the rudder will be reduced.
g) Checking and Setting the Side Rudder Servo
If your model exhibits uneven rudder extensions between left and right,
then the servo lever is not at an exact 90° angle to the steering linkages.
To check the correct positioning of the servo lever and to adjust it if
required, carefully remove the cockpit hood.
As the plastic hood is only attached with double-sided adhesive tape, it
should be relatively easy to remove. If you then remove the rear cockpit
floor, which is also only lightly fastened, you have free access to the side
rudder servo (1) and the elevator servo (2).
As with the aileron servo, both of these servo levers (3) can be easily
lifted out after the screw holding them is removed, adjusted lobe by lobe
and replaced and reattached with the screw. However, ensure that you
only carry out these settings when the rechargeable flight battery is
disconnected.
