Controlling the electric motor and butterfl y (crow) system using the Ch1 stick
(Butterfl y / crow system as landing aid: ailerons up, fl aps down)
Example 4
If you set the Expert Mode line in the » Basic set-
tings « menu to “no” (the default setting) before you
set up the appropriate model memory, please note
that the multi-function menu for this model memory
will only display a limited number of functions. In the
menu …

you can select the menu points required for this ex-
ample using the rotary control, and include them
again
in the current model memory with a brief press
on the rotary control.
Since this example really represents a procedure for
“experts”, perhaps this is the time for you to consider
setting the expert mode to “yes”, so that in future
all
the menus of the mc-22s will be available to you from
the outset when you set up further “free” memories.
However, before we start the programming of this
fourth example, and turn our attention to expanding
the basic programming we have already discussed,
we need to consider briefl y the position of the thrott-
le / brake stick at “motor OFF” or “brake OFF”. Usual-
ly the Ch1 stick is moved forward to open the throttle,
and back (towards you) to extend the brakes.
However, if you adopt this “classic” confi guration, and
switch, say, from “motor OFF” (stick “back”) to the bra-
king system, “full brake” would immediately be ap-
plied, and vice versa: if you switch from “brakes re-
tracted” to power, this would instantly switch to “full
power”.
These inter-connected effects are defi nitely not desi-
rable, and to avoid them we recommend that you po-
sition the “zero point” of both systems so that they
coincide. A “glider guider” would normally prefer the
“forward” setting, while a “power man” would probably
opt for “back”. The mc-22s allows either, so the choice
is up to you.
In the menu …

… move fi rst to the “Motor” line and set the thrott-
le minimum position to “forward” or “back”. In the fol-
lowing programming example we assume that “motor
OFF” and “brake OFF” are both set to “forward”.
Note:
If you choose “Throttle min. forward / back”, the trim
is then only active at the “idle” end of the travel, i.e. it
does not affect the whole travel of the Ch1 stick as it
would if you were to enter “none”. However, since the
Ch1 trim is generally not used for electric power sys-
tems, this is not very important. More important, ho-
wever, is the fact that …
… setting the motor to “none” automatically
disables the “Throttle too high” power-on war-
ning! For this reason please take great care to set
the Ch1 stick to the correct position before you
switch on the receiving system.
Set the “Tail” type to suit your model; in our case “nor-
mal”.
In the “Ailerons / fl aps” line enter the appropriate
number of aileron and fl ap servos.
In the last line leave the choice of “Throttle min. back”
or “none” at the default settings. However, if you op-
ted for “Throttle min. forward”, select the “Brake”
line and set the Offset point to “forward”, as de-
scribed on page 52.
The next step is to ensure that the effect of the Ch1
stick on the motor can be switched on and off.
This is carried out by moving to the menu …

… where you assign “Phase 1” with a brief press on
the rotary control, followed by selecting the name
“Normal” from the list. The asterisk (*) in the right-
hand column indicates which phase is currently acti-
ve. If you have not yet assigned a phase switch, this
will always be Phase 1. For this reason you should al-
ways assign the “Normal” name to this phase. For this
example we suggest that you assign the name “Lan-
ding” to “Phase 2”. You may also wish to enter a sui-
table phase switch transition time at this point.
The second stage is to assign a switch to these fl ight
phases, so that you can switch between the two pha-
ses in fl ight. In this case a simple switch is suffi cient,
although it should be easily accessible so that you
can switch between “Motor” and “Brake” on the lan-
ding approach without having to release a stick. A
