Programming examples – Fixed-wing models

Controlling timed sequences

using time delay and curve mixers

An interesting but little know possibility with the soft-

ware of the mc-22(s) is the facility to apply a delay of

up to 9.9 seconds to virtually any servo movement,

controlled by a switch.

The following section includes a number of examples

which illustrate how such systems can be program-

med. Once you have become familiar with these facili-

ties you will undoubtedly think of other applications.

The ﬁ rst step in the programming is to move to the

menu …

»Control adjust« (page 58)

… where you assign one of the standard sliders to

the control channel you wish to use; the slider is then

used as a tool to move to any point on the control cur-

ve during the programming procedure. In our example

this is transmitter control 7 assigned to channel 9. Ini-

tially you should not enter a time delay in the “-Time+”

column.

Next we move to the menu …

…where the selected control channel – in our examp-

le “9” – is set to “MIX only”.

Setting the control channel to “MIX only” is absolutely

essential, because the control curves of the curve mi-

xers which are described in the following example can

only inﬂ uence the output of the same channel in the

way we want if there exists no direct connection bet-

ween the transmitter control and the output. Once this

requirement is met, we can manipulate the transmit-

ter control signal in almost any way on its detour via

a curve mixer, before it is passed on to the appropria-

te output.

For this reason the next step is to move to the menu

…

… where a same-channel curve mixer is program-

med, e.g. from “9” to “9”. On the second page of the

menu we deﬁ ne the desired shape of the control cur-

ve; please note that the examples shown here are

only intended stimulate your own ideas for designing

control curves to suit your particular application.

For example, the control curve for …

… delayed switching of a searchlight after the

start of the undercarriage extension process

might look like this:

C u r v e M I X 5 9 9

I n p u t - 1 0 3 %

C u r v e O u t p u t - 1 0 0 %

o f f P o i n t L - 1 0 0

O U T P U T

1 0 0

… while the actuation of a wheel door, which clo-

ses again after the undercarriage has extended,

might look like this:

C u r v e M I X 5 9 9

I n p u t - 1 0 4 %

C u r v e O u t p u t - 1 2 1 %

o f f P o i n t L - 1 0 0

O U T P U T

… and an exponential motor start-up, or the ex-

tension of a folding power system …

C u r v e M I X 5 9 9

I n p u t - 1 0 3 %

C u r v e O u t p u t - 1 0 7 %

o n P o in t L - 1 0 0

O U T P U T

… with the drive motor (connected to output 10)

starting under the control of the same switch, but

with a time delay:

C u r v e M I X 5 9 1 0

I n p u t - 1 0 4 %

C u r v e O u t p u t - 1 0 0 %

o n P o in t L - 1 0 0

O U T P U T

1 0 0

Once you have completed the programming of the

function to meet your requirements, and have ensu-

red that it works correctly – you can check this at any

time by switching to the »Servo display« menu –

then move to the menu …
