Base setup model « menu,
enter the model name and select your preferred stick
mode and the type of receiver installed in the model.

… leave “Motor on C1” to “none” and the tail type at
“normal”. However, you must set “2 AIL 2 FL” in the
“Ailerons / camber fl aps” line for this model confi gura-
tion. In the “Brake” line set or leave “Input 1”, because
the associated C1 stick is to be used as the transmit-
ter control for operating the two airbrake servos con-
nected to receiver sockets 1 + 8.
The Offset value defi nes the neutral position of all the
mixers in the “Brake settings” sub-menu of the »
Wing
mixers « menu. Place this neutral point at about
+90%; this assumes that the airbrakes are to be re-
tracted at the forward position of the C1 stick. The re-
minder of the travel between 90% and the full travel of
the stick (100%) is then an intentional dead zone with
these two mixers; this ensures that the control sur-
faces affected by the mixers set up in the “Brake set-
tings” menu remain in their “normal” position even if
the C1 stick is moved slightly away from its end-point.
At the same time the effective travel of the transmitter
control is automatically expanded back to 100%.
In the menu …
»Control adjust« (page 78)
… assign a switch to the fl ight phase independent in-
put 9 for operating the aero-tow release. The travel of
the control for triggering the switch can be adjusted
using the “-” column.

Pressing the HELP button with the rotary control

Since the C1 control is required to operate servo 8
as well as servo 1, this link must be created using the

nus.

for servo 10 is present at (receiver) output 8, and that
for servo 8 at output 10. For more details on this pro-
cedure please turn to the section entitled “Servos run-
ning in parallel” on page 172.
The travels, and – if necessary – the direction of ro-
tation of the airbrake servo 1 and the second airbra-
ke servo, which still constitutes servo 10 as far as the
transmitter’s internal processing is concerned, can be
