- DOORS. 1 to 5:

If you select one of these functions, the appropriate output is linked to the door se-

quencer. Which wheel door or valve is controlled by which door sequencer output is

left entirely up to you, but we recommend using the Door Sequencer Assistant for the

set-up process, as this will assign the outputs correctly.

HD/FS:

- FS (Failsafe):

If a complete loss of signal occurs, affecting all receivers connected to the system,

this output moves to a previously determined position. If you wish one or more out-

puts to take up a pre-determined position if the radio link fails, select the FS option

for that output.

At this point you should leave the OUTPUT MAPPING menu and select the GENERAL

SETTINGS menu, where you will nd the TEACH FAILSAFE POSITIONS menu point.

Now use the transmitter controls to move all the control surfaces, the undercarriage

and the throttle to the positions you want them to assume if a failsafe event is trig-

gered, then press the SET button; this action stores the positions. You can test this

setting simply by switching the transmitter off: the servos will immediately move to

the positions you have just established.

- HD (Hold):

If a complete loss of signal occurs, affecting all receivers connected to the system,

this output remains in the last “good” (known) position.

7. SERVOMATCHING

The Servo-Match function provides the facility for adjusting the centreposition and

end-points of the servos connected to the backer. If you have a model aircraft with

more than one servo per control surface, this makes it possible to set up multiple

servos to move to identical positions at identical times. Since this ensures that the

servos do not work against each other, their effective life is increased, and more power

is available to move the control surfaces; matched servos also draw lower current. It

is also possible to reverse the direction of rotation of individual servos. This function is

useful if you wish to employ fewer channels at the transmitter. For example, the right

and left elevators, or the right and left landing aps, can be controlled using only one

radio channel. In models such as jets and warbirds, which by their nature have a large

number of working systems, this feature can be very important, but it can also make

transmitter programming much easier with other types of model.
