12.GYRO SETTINGS – BEFORE THE FIRST FLIGHT
It is absolutely essential to carry out Point 12 if you have installed an iGyro SAT.
You must also complete the following points before you start ne-tuning the iGyro
in ight:
+ Settings in the General Settings menu
+ Setup Assistant completed – installed orientation learned
+ Door sequencer set up if appropriate
+ All other functions assigned, including throttle, aps etc.
+ All functions set up correctly: servo centre, end-points, servo matching, Dual
+ Rates and Expo
The next step is to enter the iGyro menu with the cursor right at the bottom, so
that the menu jumps to the second page. There you will nd the Learn transmitter
stick end-points menu point. Carry out this step as described above, in order to
calibrate all the settings which have been entered in the course of the installation
procedure.
Once you have completed these steps, turn the gyro gain control (or controls, if
your model has a vector control system) to maximum, and check the direction
of effect of the gyro. The intelligent iGyro learning process effectively prevents
the need for corrections here - unless you have made an error when learning the
sticks or the installed orientation. If this should happen, simply repeat the appro-
priate point in the iGyro menu.
It is important to know that the gain control has two ranges, as explained abo-
ve: range A and range B. In range B the Assistant assigns Attitude Assist to the
aileron function. We recommend this setting on the ailerons, as it results in very
precise gyro response. During the test-ight we suggest that you turn the gain
control to the left (0% to -100%) in order to make use of this feature immediately.
Later on, you can ne-tune ranges A and B individually at any time.
Your model is now ready to y. Set the gyro gain control to 0%, and take the model
off. On this rst ight it should be trimmed out carefully without using the gyro
function.
Should you need to adjust the trims, or correct the control surface travels, during
or after that rst ight, it is essential to re-learn the stick end-points in the Gyro
menu.
