If the model-specific settings were made thus
far, the initial start can be considered. If
course, at first you should perform a "dry run",
meaning you should carefully check all the settings
once again on the ground. Incorrect programming
can damage more than just the model! In case of
doubt, ask the advice of an experienced model pilot.
If you should find during the testing that one or multiple
settings must be made for the adjustment of the rudder
effects to your control habits, the control throws are
too long or short on the whole, you should adjust this

... to your own requirements and habits.
"Dual Rate" establishes a relationship between stick
travel and control travel, see page 126:
Ail ––– 100%
Ele ––– 100%
Rud ––– 100%

On the other hand, if the maximum throws are OK and
only the reactions around the centre position are to
strong for more sensitive controls, then the "exponen-
tial" functions comes (additionally) into play:
Ail –––
Ele –––
Rud –––

If a switch is also assigned, switching can even take
place between two dual-rate/expo settings during the
flight.
This is similar for the option ...

With this option, one or multiple points of the control
curve of the throttle/brake stick can be influenced in
such a way that a pleasant or even purposeful behavior
is guaranteed.
An example of this would be the "dead" travel
of spoilers. The flaps first pass through this
after a certain "idle travel" of the brake stick
from the wing. With a corresponding "bending" of the
curve, the "dead' travel is covered more quickly. The
spoilers come out from the wing earlier and then the
remaining travel can be controlled with greater
sensitivity. (This also applies for the control of a
motor in the same manner, which can be controlled
through C1 as an alternative.)

... because "doing nothing" is the worst thing which
can be done for a winged model.
In the transmitter's home position, "Hold" is speci-
fied and "Hold" means that the receiver continuously
sends the last correctly recognized control impulse to
the servos in the model. In the best case scenario the
model flies straight ahead for an indefinite amount of
time and then hopefully "lands" somewhere without
causing significant damage! However, if something like
this happens in the wrong place at the wrong time, the
model may become uncontrollable and "tear" across
the flight field completely out of control, putting the pilot
and/or spectators at risk. Therefore, it would obviously
be beneficial to program the function "Motor off" at the
very least, in order to prevent such risks.
