Sequence for extending the gear
Task 1 opens the wheel door at the same times that were selected for retracting
the gear. The only change that needs to be made is the direction B->A must be
selected at the Action point. The software automatically copies the values for
positions I and II as soon as you select Servo 1.
Task 2 opens the main gear door immediately when the retract switch is moved
from position B to A.
Task 3 immediately starts to open the nose wheel door when the transmitter switch
is operated, but slowly.
Task 4 operates the electronic valve again and the gear is extended.
Task 5 closes the main wheel doors slowly.
Task 6 closes the secondary main wheel door after the gear is extended with a
delay of 1.5 seconds.
This example shows how a complex function is put together. It is also possible to
insert additional movements or intermediate stops at any time when opening or
closing the doors by using tasks 7 to 12.
Servo Matching
The Cockpit unit supports servo matching (ganging) in a menu item, when using
four pairs of ports marked A through D. For example, two servos attached to a single
aileron can be connected to port A, decreasing current draw and fighting between
these two servos.
Start by initializing the match channels you
will use by setting the Initial Servo Center
Position described later in these instructions.
Set up the maximum travel and expo functions
completely before matching the servos.
To match servos using the Servo Matching
function, perform the following steps:
1. Disconnect the control surface linkages from the servos to avoid high forces
acting upon the currently unmatched servos.
