GRAUPNER GR-18 - 4.2.2. Programming, transmitter without proportional controls

• Now test-y your model and ne-tune the values one by one until your preferred stabilising eect is achieved without
the model oscillating.
• It may be sensible or easier to activate the gyro for one axis only at rst, and then to establish the optimum setting for
that axis, rather than for several axes simultaneously.
4.2.2. Programming, transmitter without proportional controls
• Move the cursor to the appropriate line, in this case “Ail” for aileron.
• Press the SET button to activate the Channel  eld, select the appropriate
value (1 - 10 of OFF), then press the SET button to save it.
• First select a low value (see P factor section for starting points) and carry
out a test- ight. If gyro stabilisation is not su ciently pronounced,
increase the value step by step until the level of correction is as required;
if the model already oscillates, reduce the value step by step.
• Do not select a channel (Ch5 - Ch16); this function is only relevant to
transmitters with proportional controls.
• Move on to elevator or rudder and select the desired value (or OFF).
• Leave the settings for “Factor” and “Factor D” at OFF.
• It may be sensible or easier to activate the gyro for one axis only at  rst, and then to establish the optimum setting for
that axis, rather than for several axes simultaneously.
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 three-position switch to “Factor” and “Factor D”, and then use it to
switch the values between 0% (OFF), 100% and 200%.
Flight phase specic settings
It is possible to use a channel to control the factor value by setting up  ight phase speci c transmitter control settings,
but only if the transmitter is an MX20 / MC20 or MC32; please see the instructions supplied with your transmitter and refer
to the “Transmitter control settings” and “Flight phase settings” menu points for more information.
