The control direction of the tail rotor can now be checked. If this is
wrong, you have to change the direction of channel 4 in the "servo
setting" menu of the transmitter.
Adjustment range of the neutral impulse: 1,5 m s, 760 μ s or 960 µ s.
Tail frequency
The tail frequency can be set in a range between 50 and 333 Hz.
Adjustment range: 50, 52, 55, 58, 62, 66, 71, 76, 83, 90, 100, 111,
125, 142, 166, 200, 250 and 333 H z.
Attention
• Analog servos may only be operated at 50 Hz, otherwise the ser-
vos will be destroyed. Digital servos can be operated at a higher
frequency. This allows the model to be controlled more quickly.
• The operation of higher frequency servos is at your own risk.
• For Graupner servos of type "HBS" we recommend a setting of
333 Hz.
Tail mid
As soon as the value field "Value tail mid" is activated (field inverted),
the tail servo moves to the neutral position. The tail servo arm should
be at a 90-degree angle to the tail linkage pushrod.
The fine trim is then adjusted based on the "Tail mid" option. When
the servo is set to neutral, the tail rotor should have a pitch angle of
approx. 2 ... 3° against the torque. Check whether the control direc-
tion is correct. If this is wrong, you have to change the direction of
channel 4 in the "servo setting" menu of the transmitter.
Adjustment range: -100 ... +100
Tail limit A/B
The display "A" or "B" and its corresponding value changes automat-
ically according to the transmitter-side position of the tail rotor con-
trol stick. The two endpoints are set separately.
Select the direction with the tail rotor control stick and bring it to the
stop. The display shows the respective value for A or B.
Aerodynamically meaningful values should be set, because if the
rashes are too great, stalling of the tail rotor blades can occur. It is
also important to ensure that the servo and / or the tail rotor mech-
anism does not overrun mechanically, but the possible travel can be
fully utilized.
Adjustment range: +50 ... +200
