158 Programming example: delta and fl ying wing
On page 144, where the section on fi xed-wing model
programming starts, you will fi nd general notes regard-
ing the installation and set-up of the RC system in a
model, and - of course - this applies equally to deltas
and fl ying wings. The information on test-fl ying and refi n-
ing the settings is also relevant, including the section on
programming fl ight phases.

In their characteristic shape and geometry, deltas and
fl ying wings differ very signifi cantly from “normal” models
even at fi rst sight, but the differences in the requisite
servo arrangement are rather more subtle. The “clas-
sic” model delta or fl ying wing generally has only two
control surfaces, which act both as ailerons (in opposite
directions) and as elevators (in the same direction), in a
similar way to the superimposed rudder / elevator func-
tions of a V-tail. More modern designs tend to be more
complex; one (or two) inboard control surfaces may be
used purely as elevators, while the outboard ailerons
also act as elevators, but to a reduced extent. If a fl ying
wing has four or even six wing control surfaces, it is
certainly feasible nowadays to set them up with camber-
changing fl ap functions and / or even a butterfl y (crow)
system.
However, most of these models still rank as “classic” del-
tas and fl ying wings, and for them the servos should be
connected to the receiver as follows (see also page 44):
Airbrakes or throttle or speed
controller (electric motor)
Right flap
Left flap
Rudder (if present)
Left elevon (ail. / elev.) servo
Right elevon (ail. / elev.) servo

If your delta or fl ying wing is of more “modern” confi gura-
tion, the “normal” servo sequence has proved useful;
this arrangement can also be used for canards:
Airbrakes or throttle or speed
controller (electric motor)
Right flap (/ elevator)
Left flap (/ elevator)
Rudder (if present)
Left elevon (aileron / elevator)
Elevator (if present)
Right elevon (aileron / elevator)

Depending on the receiver servo sequence you select,
you should fi rst move to the …
“Basic settings” menu (pages 56 … 62)
… and select the following options in each line:
“ motor at C1 ”:
•
“none”:
The brake system is “retracted” at
the “ forward ” position of the throttle

tion and the “Brake

The warning message “Throttle too

“Idle forward” or “Idle rear”
The Ch 1 trim operates either
forward or back. If you switch the
transmitter on with the throttle stick
too far in the direction of full-throttle,
you will see the warning message
“Throttle too high” on the screen.
The “Motor stop” option is activated ,
and the “Brake

in the “ Wing mixers ” menu are
disabled .
“tail type”: “Delta / fl ying wing” or “Normal”
“aile/fl ap”: Two ailerons “2ail” and - if present -
two fl aps “2fl ”.
The primary function of these settings is to defi ne the
range of wing mixers which the software makes avail-
able. If you select the “
Delta / fl ying wing ” tail type, the
software automatically superimposes the elevator and
aileron functions. In this case the mixer ratios can be
adjusted by varying the Dual Rate settings in the “
