15. Assignments/functions of the receiver
The receiver is already installed in the helicopter. It is equipped with a built-in gyro for tail rotor balance.
Pin assignment:
1. Nick servo
2. Left roll servo
3. Right roll servo
4. Not assigned (intended for a tail servo);
this helicopter, however, is controlled
by an electric motor
5. Not assigned (intended for an additio-
nal speed controller)
6. Not assigned
7. Control of the motor for the main rotor
8. Control of the motor for the tail rotor
9. Speed control of the tail rotor and
consequently tail stabilisation
10. Control of total swashplate servo throws
11. Power LED
If the helicopter responds too reluctantly during the first hovering flights, turn the "EXTENT" control (ill. 16, pos. 10)
slightly clockwise. This increases the total throws of the swashplate. Turning the control anti-clockwise decreases the
throws.
If the helicopter still shows a tendency to move in one direction with the fuselage tip although you have adjusted the
trim slider for the tail function (ill. 1a, pos. 11), the speed of the tail rotor must be increased or decreased.
Use the "MIX" control to make the adjustment (ill. 16, pos. 9). Turning it clockwise increases the speed of the tail rotor
and the anti-torque with it, turning it anti-clockwise decreases the speed of the tail rotor and the anti-torque with it.
