Caution, important!
Since electrical drives can be very dangerous, we recommend disconnecting the motor from the controller for any
subsequent maintenance and setting work. This reliably prevents inadvertent start-up of the mechanics.
Inspection of the rotor-head linkage:
Call a helicopter programme with a 3-point 120° swash-plate control (HR-3) on your remote control transmitter and set the
servo paths in the swash plate mixer programme to 50%.
1. Move the pitch control lever from bottom upwards and ensure that the swash plate also moves horizontally from
bottom up. In the centre position of the control lever, the levers of the three swash plate servos must be horizontally
aligned. If required, change the motion direction of individual servos.
2. Move the control lever to the right and then to the left for the roll function. The swash plate then also has to tilt to the
right and then to the left. If the swash plate motions are opposite to the control directions, change the running direction
for the roll function at the transmitter (reverse setting).
3. Move the control lever for the nod function to the front and then back. The swash plate then also has to tilt to the front
and then to the back. If the swash plate motions are opposite to the control directions, change the running direction for
the nod function at the transmitter (reverse setting).
Important!
The swash plate motions for the roll and nod functions should equally strong in all directions.
4. Check the centre position of the servo. If the control lever for the pitch function is in the centre position, the servo
levers must be aligned perfectly horizontally. Strong malpositions of the servo levers can be removed by repositioning
the servo lever. The fine settings are made with the sub-trimming function at the transmitter.
5. Check the angle of attack of the rotor blades with a rotor blade setting gauge. If the control lever for the pitch function
is in the centre position, the angle of attack of the rotor blades should be 0°. If required, re-adjust the angle with the
linkage rods (see page 10).
6. At correct settings, the servo levers, swash plate and swash plate tappet levers must be aligned horizontally when the
control lever is in its centre position.
7. Push the control lever for the pitch function to the top position. The angle of attack of the rotor blades now has to be
between 11° and 13°. The pitch curve at the transmitter should be set linearly. If the control lever for the pitch function
is moved to the bottom-most position, the rotor blades must reach an angle of attack of -11° to -13°. If required, set
the pitch function with the swash plate mixer or the servo path setting at the transmitter. These settings are required
for the flight mode "freestyle".
8. For the flight mode "normal", light the pitch curve in the bottom-most setting to 40 to 45%. Lift the pitch curve to 55
to 60% in the middle range. The rotor-blade angle of attack should then be -2° to -3° in the bottom-most position of
the pitch control lever. In the centre position, the angle should be approx. 3°.

Inspecting the tail rotor linkage:
When the control lever for the tail function is moved to the right, the slider sleeve of the tail rotor linkage must move towards
the tail rotor casing. If the slider sleeve moves towards the rotor, change the running direction of the tail servo at the
transmitter.
Also check the effective direction of the 3-axis gyro in this context. If the fuselage tip of the helicopter is turned to counter-
clockwise to the left when viewed from above, the sliding sleeve must also be moved towards the gear casing by the gyro.
If this is not the case, change the running direction of the tail servo at the gyro. Then adjust the maximum deflection of the
tail servo at the gyro.
Important!
The slider sleeve must not stop mechanically in the two maximum deflections. Keep a distance of approx. 0.5 mm
to the tail rotor head or the tail rotor casing.
