Delta And Fl Ying Wing Models - GRAUPNER mx-20 Hott Programming Manual

Delta and fl ying wing models
Of course, the general comments regarding the
installation and the adjustment of the RC system to a
model at the beginning of the wing model programming
on page 236 also applies for delta and fl ying wing
models! Similarly, the comments for test fl ying and fi ne-
tuning the settings to the programming of fl ight phases
also apply.

Delta and fl ying wing models differ signifi cantly from a
"normal" fl ight model due to their unique characteristic
shape and geometry. The differences in the servo
arrangement, on the other hand, are more subtle. For
example, with "classic" delta/fl ying wing models, only
two rudders are normally provided. They are responsible
for both "transverse" and "height/depth", like the side
rudder/elevator function on a V-tail unit.
With more elaborate designs, on the other hand, it
may be the case that one (or two) interior rudders
have only an elevator function and the exterior ailerons
only support the height/depth function, under certain
circumstances. Even with a four or six-fl ap wing the
use of camber changing fl ap functions and/or even a
crow system is now entirely possible. In all these cases,
however, the following assignment of the receiver
outputs should be used, see also page 57. Unneeded

... the necessary settings are made:
"Motor at C1" "none" or "Throttle min front/rear"
"Tail type" "Delta/fl "
"Aile/FL" "2AIL" (appears automatically).
Insofar as necessary, expand the
default "2AIL" with 1, 2 or 4 camber
changing fl aps ("1FL", "2FL" or "4FL").
"Brake" remains or is only of interest with a
delta or fl ying wing aircraft of the type
"2 AIL 1/2/4 FL". In this case, see
under "Brake offset" on page 83.
These settings specifying the model type affect the
available "Wing mixers" fi rst and foremost. Therefore,
the options are discussed separately for two-fl ap and
multi-fl ap models in the following:
Delta/fl ying wing of the type: "2AIL"

Motor at C1
Tail type
Aile/flaps
Brake Off
In keeping the standard default "2AIL" in the "Aile./
FL" line, the elevator and aileron control, including the
trimming function, are only mixed automatically on the
(page 82)
software side. On the transmitter side, however, you can
infl uence the effect of the elevator and aileron joystick in
the "Dual Rate / Expo" menu, page 108.

Due to the specifi c idiosyncrasies of this model type,
additional settings lead to incompensable moments.
