Operation Manual

Example
model:
'FgB"
The
picture
shows a typical
F3B class
competition
mod-
el.
The control system
is
quite
complex.
Each aileron
and
each
flap is operated by
its own servo.
This makes
"Quadro"
and
"aileron
brake"
(crow)
control systems
possible.
In
normal tlight the ailerons
support the
cam-
ber-changing
flaps, and
vice versa; for
landing the
flaps are def
lected f ully down
and the ailerons
Jully up
Memory
No.: I
("aileron
brake"
function).
Elevator compensation
is
mixed in with the
camber-changing
flap
movement and
the aileron
brake system
to compensate
for
pitch
trim
changes.
Flap
movement can be
mixed in to support
eF
evator
movement.
A radio-controlled
towhook
(towhook
and
aero{ow
release treated as
the same
for control
purposes)
is
an
optional addition.

Note:
when adjusting the
mixing inputs
it can be
very
useful
to switch off any
inputs
which are
not needed

Possible
modifications:
Control
of the FLAP
input via stick
instead of slider
Flap control with one
servo only;
in this case they cannot support
the aileron
function.
