102 Programming example: fi xed-wing model
Controlling the electric motor and butterfl y (crow) system using the Ch 1 stick
(Butterfl y / crow system as landing aid: ailerons up, fl aps down)
Example 4
Before we start the programming of this fourth example,
and turn our attention to expanding the basic program-
ming we have already discussed, we need to consider
briefl y the position of the throttle / brake stick at “motor
OFF” or “brake OFF”. Usually the Ch 1 stick is moved
forward to open the throttle, and back to extend the
brakes. However, if you adopt this “classic” confi gura-
tion, and switch, say, from “motor OFF” (stick “back”)
to the braking system, “full brake” would immediately
be applied, and vice versa: if you switch from “brakes
retracted” to power, this would instantly switch to “full
power”.
It is certainly possible to make a “virtue” out of this
“vice”: a “glider pilot” – usually fl ying with “brakes re-
tracted = forward” will only switch to motor “ON” when
necessary, and then reduce power to suit the situation
(and – we hope – does not forget to move the Ch 1 stick
back to the “forward” position when switching back). In
contrast, a typical “power pilot” would probably operate
with the opposite priority, i. e. he would only switch to
“brake” when necessary, etc.. In any case, it is possible
to avoid these inter-connected effects by positioning the
“zero point” of both systems so that they coincide. The
above considerations mean that a “glider pilot” will prob-
ably prefer the “zero point forward” arrangement, while a
“power pilot” might well decide on “zero point back”.
The
mx
-16iFS transmitter can cope with whichever
arrangement you prefer. However, the following section
assumes that both “OFF” positions will be set to “for-
ward”. If you prefer the alternative arrangement, there
is no problem: the only difference compared with the
version described here is that you would select “no/inv”
in the “motor on C1” line of the »
base sett. « menu. All
the other settings can be adopted as described.

Important note:
As it is essential to set the motor to “no”, this also
automatically disables the “Throttle too high” power-
on warning! For this reason please take great care
to set the Ch 1 stick to the correct position before
you switch the receiving system on.
The next step is to ensure that the speed controller con-
nected to receiver output 1 is switched off “at the right
end”. To accomplish this you may have to move to the …

For safety’s sake you should check this setting now,
before you continue with the programming procedure.
Take the transmitter and model to a location where it
is safe to run the motor. Switch the transmitter on, and
move the Ch 1 stick to the motor “OFF” position, i. e. ei-
ther fully forward or back. Hold your model fi rmly, or ask
a friend to hold it for you. Check that the propeller is free
to rotate without causing havoc, then connect the fl ight
battery and switch your model’s receiving system on.
If the motor does NOT run when the stick is the appro-
priate “forward” or “back” position, then everything is in
order. However, check the system anyway by gradually
advancing the stick until the motor begins to run. When
you are satisfi ed, stop the motor, then switch off the
receiving system in the model and fi nally switch off the
transmitter.
Note:
If the motor does not start, or spins in the wrong direc-
tion, there are other problems which you must correct
before you resume programming. For example, check
the wiring of your motor, and refer to the operating
instructions supplied with your speed controller.
Once you are confi dent that the direction of the Ch 1
stick is “correct” as far as the motor is concerned, the
next step is to ensure that you can switch its effect on
the motor on and off, so that you can also control the
braking system. This is carried out in the …
