8-Fl Ap Wings - GRAUPNER MC-20 HoTT Programming Manual

Eight-fl ap wing
mc-20
The standard features of the
convenient control of up to 8 servos for aileron/
camber fl ap functions.
In the following we will consider a model without
motor drive and without spoilers in the wings. The
example is also based on the assumption that the
model is already mechanically pre-adjusted, that
the defl ection of all rudders to the correct side has
been verifi ed, that these items will be checked again
in the context of programming and that adaptations
will be made as necessary via servo swapping at the
receiver and/or in the Servo adjustment menu.
The servos should be connected to a suitable
receiver as follows:
2 11 6 9 10

For the control of all fl aps, up to two additional
proportional controls are required in addition to
the two joysticks or, alternatively up to two 2-way
switches.

• The servos 6 + 7, 9 + 10 and 11 + 12 now move
for the aileron control just like servos 2 + 5. Aileron
trimming also affects all of these servos.
• The C1 joystick only actuates the servo connected
to receiver output 1.

In doing so, the basic programming of the eight-fl ap
wing is completed.
Camber fl ap positioning and fl ight phases
First program two or more fl ight phases in the
»Phase settings« and »Phase assignment« menus.
Also take this opportunity to change the standard
default "global" for trim in the »Stick mode« menu,
page 104 to "phase", thus allowing modifi cations to
meet individual preferences.
An example of fl ight phase programming can be
found on page 288.
