software switch was tripped when the signal exceeded
or fell below the programmed threshold value.
An alternative mode is now available which works as fol-
lows: when the signal first exceeds or falls below the
threshold value, the software switch is tripped and swit-
ches off. It then stays off until the signal exceeds or falls
below the threshold value a second time. In electronic
terms this method of working corresponds to the flip-flop.
The currently active mode is indicated by a single letter
following the activated transmitter control. "A" stands for
alternative mode, and "N" for normal mode. You can
switch between the two modes by pressing the soft-key
>MODE<.
9. TIMR[02] Optional automatic or manual reset for
Timers 1 and 2
All the functionality of Timers 1 and 2 available in the original
software is retained, but it is now also possible to sup-
press the forced timer reset when you switch on the
transmitter. If "CLR" appears in the "P/C" column of the
TIMR[03] menu, the timer will be reset in the usual way.
If, on the other hand, you set "INH", the transmitter
retains the times recorded up to the point where the
transmitter is switched off. A typical application for this
facility would be to record the day's total operating
hours.
10. Model memory timer, records operating time for
each model
In addition to Timers 1 and 2 and the transmitter opera-
ting hours recorder, the home display now incorporates
a model memory timer. The display in the form of
"Hours:Minutes" is shown above the transmitter opera-
ting time, and features the suffix "MDL" (for "model").
You can reset the value to zero by holding the soft-key
>MDtmr-RSET< (button 5) pressed in. The same proce-
dure is now used to reset the transmitter operating hours
timer with >TOtmr-RSET< (button 6).
11. Increased buzzer volume
The volume of the signal buzzer (piezo sounder) has
been increased; this makes it possible to hear warning
signals even when you are hovering a glow-powered
model helicopter close to you.
Operating instructions
Multisoftmodul FC-28 V 3.2
Functions already implemented in V3.1:
12. Optional global or separate effect of the following
functions:
Transmitter control stick mode - FUNC[21]
Transmitter control trim - TRIM[29]
Servo centre offset - SBTR[51]
Camber-changing flap and aileron neutral trim -
NTRM[66]
The transmitter stick mode in the FUNC menu now
works globally, i.e. the stick assignment selected in the
"Normal" flight mode is automatically copied into the
other flight modes. This change simplifies the whole pro-
gramming system by reducing the number of essential
programming steps. You can still opt to program the stick
mode separately for each flight mode in the previous
way (MODE3DSEPARATE), i.e. no facilities have been
removed.
The trim value memory in the TRIM menu can now also
be set to global effect in the Trimrate sub-program.
However, as in the previous version it is still possible to
switch to separate stored trim values for each flight
mode - this is the preferred mode for helicopter pilots in
any case.
If you set Trim memory to GLOBAL effect, you can still
set an individual flight mode dependent trim using the
Offset-Mix menu (OFST). To exploit this facility you will
then need an external mixer trimmer (see also the
description on page 56 of the main FC-28 V3.0 instruc-
tions).
The menus Subtrim (SBTr) and neutral trim (NTRM) now
also feature the options of GLOBAL and SEPARATE
effect for these settings.
13. Linked model memory change-over, can be stored
Some model pilots make use of the facility to double the
number of maximum flight modes from five to ten by lin-
king two model memories. In the previous version of the
software it was necessary to re-define the link to the
slave memory every time a new main model memory
was selected. In the V3.1 software this link is stored
permanently in the master model memory.
14. New menu position for code number input
The position for code word input has now been moved to
a position immediately before "program select". The
result is that you can switch the system on and imme-
diately use the model memory which was last in use,
including the timer functions. You do not need to enter
the code word until you wish to call up the programming
menu.
15. SWMx[69] New swashplate -> tail rotor mixer
The helicopter program has been expanded by a swas-
hplate (pitch-axis and roll-axis) to tail rotor mixer. The
purpose of this mixer function is to prevent the model
rotating around its vertical axis when a major cyclic con-
trol command is given. The mixer has been incorporated
in the Swash-Mix menu (SWMx[69]), and is termed
SWASH>SEI. It can be activated and adjusted in the
same way as the existing SWASH>MOT mixer. The
direction of mixing is set automatically by the selection of
main rotor direction in the REVO-Mix menu.
