Axis Assignment - GRAUPNER GR-18 Manual

Tail limit A/B
Default setting: 50
Limits the tail servo travel. It must be set so that it never reaches its mechanical limits but so that the full travel can be
used. Values that are suitable in terms of aerodynamics should be selected here. If the travel is too large, this may cause
the servo to stall.
Expo
"Expo" is set to "Yes" by default; this means that within the controller an exponential value of approx. 25% is used on the
Swp and approx. 30% on the tail. The setting can also be made on the transmitter (dual rate/expo). To do this, set the
value to "No"; however, you must set similar values on the transmitter for the first flight.
Logging
Logs the respective servo function on the SD card to carry out an evaluation and error analysis later on.
0 = no logging
1 = roll and nick logging
2 = roll logging
3 = nick logging
4 = tail logging
We recommend always logging at least one function.
Expertmode
"Expertmode" is set to "No" by default. Even experts should stick with this setting when carrying out the first
steps with the new system (there are much fewer options in the Swp and tail menu) and they should only switch
to Expertmode and its additional options if they need to and when they have got used to the system.
You have completed the basic model settings and can now move on to the following settings:

Setup
Setup: Yes/No
Assignment of the gyros and their operating direction.
If you have not already done so, you must now set the K1-4 servo directions so that everything works correctly.
In the receiver's "Axis assign" menu, go to the "Setup" option and set it to "Setup: Yes". Now assign the axes as follows:
• On the transmitter, briefly set the roll command fully to the right; the roll axis is highlighted. You will then have both
hands free again to operate the helicopter.
• Roll the helicopter more than 45 degrees to the right → the identified axis with the required prefix is displayed, the
field is no longer highlighted and identification of this axis is complete
• Now do the same for nick: on the transmitter, briefly set the nick command so that it is fully forward
• Roll the helicopter more than 45 degrees forwards; the axis is displayed, the field is no longer highlighted and
identification of this axis is complete
• Finally complete the procedure for the tail: on the transmitter, briefly set the tail command fully to the right
• Turn the helicopter so that the nose turns more than 45 degrees to the right; the axis is displayed, the field is no
longer highlighted and identification of this axis is complete
The gyros and operating directions have now been assigned. Now check to make sure that the operating directions are
correct.
