Turning away with the ailerons/landing aps
extended
If you move the ailerons upward for the landing, the
result is often a turning away over the longitudinal axis
due to various servo paths of the aileron servos or due
to design precision. Therefore, the model begins to au-
tomatically hang the left or right wing. This is also easy
to compensate for with a mixer “C1 AI” depending
on the position of the ailerons/landing flaps.
The mixer must be switched on and off with the same
switch with which you can switch the aileron/landing
flap function on and off (see previous page). Therefore,
it only works with the aileron/landing flap function acti-
vated. The appropriate value must be tested in flight.
One additional comment regarding …
“FAIL-SAFE setting”
You utilize the safety potential of this option by
programming at least the motor throttle posi-
tion for combustion models to idle and the
motor function for electrically powered models to stop
for a Fail-Safe case. If interference should occur, the
model is then less likely to fly off on its own and cause
damage to property or even personal injury. If you
additionally program the fail-safe positions of the rud-
ders to that the model flies in gently sinking circles in
the event of a failure, there is a good chance that the
model even lands relatively gently on its own in the
event of a continuing connection failure. You also have
sufficient time to re-establish the connection if the
entire 2.4 GHz frequency band is temporarily disrupted.
In the receiver’s condition as supplied, however, the
servos maintain their last validly recognized position
(“hold”) in the event of a fail-safe situation. As de-
scribed on page 216, you can define a “Fail-safe posi-
tion” for each receiver servo output (Fail-safe mode).
Summary
The settings described on this page are especially use-
ful for the “expert” who would like to have an entirely
neutral, precisely flying F3A model acrobatic model at
his or her disposal.
It should be mentioned this takes a lot of time, effort,
instinct and know-how. Experts even program during
the flight. To do this, however, is not suggested for an
advanced beginner who ventures into an F3A acrobatic
model. It would be best to turn to an experienced pilot
and carry out the settings step by step until the model
has the desired neutrality in its flight behavior. Then the
pilot can begin to learn the not always easy to perform
acrobatic figures with a model which flies faultlessly.
