The control direcon of the tail rotor can now be checked. If this is
wrong, you have to change the direcon of channel 4 in the "servo
seng" menu of the transmier.
Adjustment range of the neutral impulse: 1,5 ms, 760 μs or 960 µs.
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 Hz.
Aenon
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 operaon of higher frequency servos is at your own risk.
For Graupner servos of type "HBS" we recommend a seng of
333 Hz.
Tail mid
As soon as the value field "Value tail mid" is acvated (field inverted),
the tail servo moves to the neutral posion. 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" opon. 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-
on is correct. If this is wron
g, you have to change the direcon of
channel 4 in the "servo seng" menu of the transmier.
Adjustment range: -100 … +100
Tail limit A/B
The display "A" or "B" and its corresponding value changes automat-
ically according to the transmier-side posion of the tail rotor con-
trol sck. The two endpoints are set separately.
Select the direcon with the tail rotor control sck and bring it to the
stop. The display shows the respecve 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 ulized.
Adjustment range: +50 … +200
