ROBBE FC-28 V 3.2 Bedienungsanleitung Seite 7

In the MxTY[13] menu you can now change the pre-
viously fixed flight mode names "NORMAL", "FLIGHT1",
"FLIGHT2" etc. to new, more informative ones: move the
cursor to the pre-set flight mode names and select the
appropriate symbols using the soft-keys >+< or >-<.
Glider pilots will appreciate this function, as it is now pos-
sible to change the flight mode priorities simply by swap-
ping over the mode names.
Caution: if you change the mixer type (STND, GLID etc.)
after entering a name for a flight mode, the name you
have entered will be erased.
3. FUNC[21] Mixer switches (external switches) can be
programmed as channel switches
Until now channels 1 to 8 could only be influenced by
those functions classed as transmitter controls (sticks,
sliders and special switches), although they could also
be influenced indirectly by mixers. In the FUNC[21]
menu you can now also program the external switches
1-8 and A-D to provide direct control of these channels.
A typical application would be to use a mixer switch to
retract and extend a retractable undercarriage. You can
reverse the direction of effect of the switch by changing
the prefix (+/- button).
4. PMIX1[40] to PMIX6[45] MIX-UNMIX function for
mixers PMIX1-6
The MIX-UNMIX function, which is integrated into the
mixers PMIX1 to PMIX6, determines whether changes
to the characteristics of the master control (by means of
AFR[15] or D/R[16]) are included or ignored when the
value of the slave signal is calculated. The MODE3DUN-
MIX option corresponds to the earlier method of working;
in this mode the settings in the AFR[15] and D/R[16]
menus are ignored. MODE3DMIX includes the settings
in these menus when the slave signal is calculated.
An example will make this easier to understand: using
V3.0 or V3.1 we will assume that a function named "A"
was mixed with a function "B", with the result that a com-
mand using function "A" (3D master) caused a move-
ment in the "B" servo (3D slave) according to the mixer
ratio which you had set. If the travel of channel "A" was
subsequently reduced using AFR or Dual Rates, this had
no effect on the resultant servo travel of channel "B", as
such settings were ignored.
If you wanted to restore the programmed ratio between
the control surface travels, you had to re-adjust the
mixer ratio. This method of working is still available, and
if you prefer it you should use the UNMIX option under
V3.2. However, by selecting the MIX option you can
save yourself the extra effort, as the travel of channel "B"
varies according to any manipulations you make to the
transmitter control for function "A".

5. PMIX1[40] Freely programmable 9-point curve mixer
You can now convert the freely programmable mixer
PMIX1 from the standard linear method of working into a
9-point curve mixer just by pressing a button.
To do this move the cursor to the MIX> field and press
the soft-key >CURV<. The method of programming the
mixer curve is as already described for the existing curve
mixers PCrv[57] and TCrv[54].
This function is ideal for controlling the mixture setting of
a carburettor, i.e. for altering the mixture according to the
position of the throttle barrel.
6. GYRO[72] Gyro suppression mixer with graphic dis-
play
A graphic display has now been integrated into the trans-
mitter-based gyro suppression mixer for the tail rotor
control system, with the aim of making the relationship
more easily comprehensible than by pure percentage
values. Nothing else has changed in the way the menu
works.
7. F/S[22] Fail-safe test function
If you are using a PCM receiver you can check the fail-
safe function using the soft-key >CHCK<, which is now
an integral part of the F/S[22] menu.
Hold this button pressed in, and the servos take up any
fail-safe positions you have programmed.
8. CHSw[35] Alternative switched functions in CHSw
menu (transmitter controls as mixer switches)
Complex switching tasks operated by the main transmit-
ter sticks can present problems, and to provide a soluti-
on the CHSw menu has now been supplemented with an
alternative method of tripping extra functions.
In the normal mode using the previous software, the
