Model Deltas And Fl Ying Wings - GRAUPNER mx-16 ifs Programming Manual

Programming example: Delta / fl ying wing
On page 94, where the section on fi xed-wing model
programming starts, you will fi nd general notes regard-
ing installing and setting up 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 ning
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 38):

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:

Depending on the receiver servo sequence you select,
you should fi rst move to the ...
»base sett.«
... menu and select the following options in each line:
„motor on C1": • "no":
The brake system is "retracted" at
the "forward" position of the throttle
/ brake stick, and the "Brake
N.N.*" mixers in the »wing mixer«
menu are activated.
The warning message "Throttle too
high" (see page 18) is disabled.
* N.N. = Nomen Nominandum (name to be stated)
"tail type":
"aile/fl ap":
(pages 46 ... 49)
The primary function of these settings is to defi ne the
range of wing mixers which the software will make
available. If you select the "delt/FlW" (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 »D/R expo« menu (see page 66).
If you select "delt/FlW", all settings of the "N.N.*
elev" wing mixers in the ...
• "no/inv":
The brake system is "retracted" at
the "back" position of the throttle
/ brake stick, and the "Brake
N.N.*" mixers in the »wing mixer«
menu are activated.
The warning message "Throttle too
high" (see page 18) is disabled.
• "idle fr(ont)" or "idle re(ar)":
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 "Brake N.N.*" mixers in the
»wing mixer« menu are disabled.
"delt/FlW" or "normal" type
Two ailerons "2 aile" and – if
present – two fl aps "2ail 2fl ".
