Fixed-wing models
Fixed-wing models
This program provides straightforward, carefully tailo-
red support for conventional models with up to two ai-
leron servos and four fl ap servos, V-tail models, fl ying
wings and deltas with two elevon (aileron / eleva-
tor) servos and up to four fl ap servos. However, the
vast majority of power model and gliders belong to
the “normal” tail type with one servo each for eleva-
tor, rudder, ailerons and throttle (or electronic speed
controller, or airbrakes on a glider). There is also the
special model type “2 EL Sv 3+8” which automatically
provides a means of connecting two elevator servos
to channels 3 and 8.
If the model has a V-tail instead of a standard tail con-
fi guration, you should select the “V-tail” type in the
»
Model type « menu, as this mixes together the ele-
vator and rudder functions in the required way, i. e.
each tail control surface is actuated by a separate
servo, and both assume superimposed elevator and
rudder functions.
If your model features two separate aileron servos,
the aileron travels can be set up with differential mo-
vement, i. e. the down-travel can be set independent-
ly of the up-travel. Finally the program caters for cam-
ber-changing fl aps which can be operated, for ex-
ample, by the transmitter control assigned to input “6”
in the »
Transmitter control adjust « menu.
The “fl ap differential” function can be used to provide
differential travel when the fl aps are programmed to
follow the aileron function.
For deltas and fl ying wings it is easy to set up mixed
elevons, i. e. the aileron and elevator functions can be
carried out by common control surfaces at the trailing
edge of the right and left wing. The program contains
the appropriate mixer functions for the two servos as
standard.
Up to eight fl ight phases can be programmed in each
of the forty model memories provided by the
mx
-
24s (see the » Phase settings « and » Phase assign-
ment « menus). A copy facility is provided, making the
setting of individual fl ight phases much easier (see
the »
Copy / Erase « menu).
Four timers are available at all times when fl ying. Ad-
ditional timers and a lap counter with stopwatch func-
tion can also be displayed on-screen, separately for
each fl ight phase (»
Timers (general) « and » Flight
phase timers « menus). The screen also displays the
transmitter operating time and the time which has
elapsed for each model memory.
Phase-specifi c trims can be stored for fl aps, ailerons
and elevator (see the »
Phase trim F3B « menu).
The digital trim positions can be stored either globally
or separately for each fl ight phase – with the excepti-
on of the C1 trim. The digital motor-cut trim provides
a simple means of re-locating the correct idle thrott-
le setting.
“Dual Rate” and “Exponential” can be programmed for
aileron, rudder and elevator, giving two modes of con-
trol in each fl ight phase.
As an option, a transmitter control (C1 stick, side-
mounted proportional control, INC / DEC buttons or
switch) can be assigned to inputs 5 … 8, separately
for each fl ight phase (see »
Control adjust « menu).
In addition to eight freely assignable linear mixers, the
program offers four curve mixers (see »
Free mixers «
menu), four dual mixers (see » Dual mixers « menu)
and fl ight phase specifi c eight-point curves (see
»
Channel 1 curve «) for channel 1 (throttle / brake).
The » Wing mixers « menu presents you with a list of
pre-defi ned mixers and coupling functions from which
you can choose; the list varies according to the num-
ber of wing-mounted servos you have entered.
1. Multi-fl ap menu: control of camber-changing fl aps
as ailerons. Infl uence of aileron trim on fl aps when
operated as ailerons, fl ap differential, travel of the
fl ap function of all pairs of ailerons and fl aps, aile-
rons operating as camber-changing fl aps. Elevator

2. Airbrake settings: Butterfl y (Crow), differential re-
duction, elevator curve
