Programming example: deltas and ﬂ ying wing model aircraft

On page 120, where the section on ﬁ xed-wing mo-

del programming starts, you will ﬁ nd general notes re-

garding the installation and set-up of the RC system

in a model, and – of course – this also applies to del-

tas and ﬂ ying wings. The information on test-ﬂ ying

and reﬁ ning the settings is also relevant, including the

section on programming ﬂ ight phases.

Even at ﬁ rst sight, deltas and ﬂ ying wings differ very

obviously from “normal” models in their characteris-

tic shape and geometry, but the differences in the ser-

vo arrangements required are rather more subtle. The

“classic” 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 di-

rection), in a similar way to the superimposed rudder /

elevator functions of a V-tail.

Modern designs tend to be more complex than this:

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 cam-

ber-changing ﬂ ap functions and / or even a butterﬂ y

(crow) system.

However, most of these models still rank as “clas-

sic” deltas and ﬂ ying wings, and for them the servos

should be connected to the receiver as follows (see

also page 35):

In accordance with this servo sequence we move to

the menu …

and select the “Delta / ﬂ ying wing” type in the “tail”

line; at this point the “Ailerons / ﬂ aps” line below it au-

tomatically displays “2 AIL”.

These settings primarily affect the list of available mi-

xers, because elevator and ailerons are automatical-

ly mixed together by the software when the “Delta /

ﬂ ying wing” tail type is selected. At the transmitter

you can adjust the control travel of the elevator and

aileron stick in the »Dual Rate / Exponential« menu

(see page 64).

Note:

If your model features more than just these two con-

trol surfaces, then you should skip this section and

continue reading in the right-hand column, under del-

ta / ﬂ ying wing designs of “modern” layout.

Certain settings in the »Wing mixers« menu (see

page 84) may be useful with the “Aileron 2  4 rud-

der” mixer, and you may even wish to experiment with

Settings beyond those described can result in unwan-

ted moments which it may be impossible to correct,

due to the speciﬁ c characteristics of this type of mo-

del.

In contrast, delta and ﬂ ying wing designs featuring

more than two wing ﬂ aps can sometimes cope with

these moments. For example, the “ballooning” mo-

ment (= up-elevator effect), caused by deﬂ ecting both

ailerons up, can be corrected by lowering the ﬂ aps (=

down-elevator effect) to the requisite degree.

If your delta or ﬂ ying wing is of this more “modern”

conﬁ guration, the “normal” servo sequence has pro-

ved to be useful:
