GRAUPNER 33575 Manual page 17

Note
If the model is too agile in mode 3, it is then recommended to
set in the transmitter DUAL RATE and/or EXPO for this mode.
Thus the model will react in a more docile way. In the Rate mode
the model tries to reach the controlled rate. Also in mode 2
EXPO can be useful.
Aileron/elevator/rudder:
Shows the programmable factors for the corresponding control
surface.
The gyro correction can also be disabled by setting the value to
OFF. Do not exceed 4 - 5 as maximum value for the normal flight
phase, 2 - 3 for speed, 3 - 6 for landing. The maximum value of
10 should be reserved for torque-rolls only.
Factor (general sensitivity)
Setting this value the 3 parameters will be influenced contem-
poraneously.
General sensitivity for all gyros, action grade settable through a
controller between 0 and 200%
Move the cursor to the Factor line. Move the cursor to reorder
the factor for aileron, elevator and rudder by using a proportional
control (adjustment range up to 200%; channel value -100%
means a factor of 0%, channel value 0% means 100%, and
+100% means 200%). This makes it a very easy matter to match
the gyro's corrective effect to the model's airspeed. In particular,
higher gyro gain can be used for the landing approach - without
the need to switch flight phases.
Once you have found the optimum settings, you can set up a
transmitter switch to control the gyro, i.e. for switching between
gain settings. For example, you could assign a 3 position switch
to "Factor", and then use it to switch the values between 0%
and 100% (OFF) so as 200%. In the transmitter the servo dis-
play for this 3 functions switch must indicate -100, 0 and +100%.
Note
The OFF value means a gyro action of 100%!
Good to know!
The standard factor should cause the gyros to correct the mod-
el's attitude quickly when it is upset by an outside influence.
Without causing oscillation, but in practice the optimum values
for a particular model can only be found by flight-testing. If the
model shows little or no automatic stabilization with the default
settings, the value should be raised; on the other hand. If the
model oscillates (wave-like movements in flight), the value should
be reduced.
