On the second line of Expo/DR screen you can select to which stick (RUD, ELE, THR, or AIL) the
settings below apply. The graph changes as you enter values so you can see if you are adjusting the
line in the correct way and get a sense of proportion. Here rudder is selected.
For each control you can input values for both expo and D/R by highlighting the field and using the
navigation buttons to change the value. For example, to edit an expo value, press the DOWN key
until the cursor blinks on the expo value. Then use the LEFT/RIGHT keys to change the value. If the
stick is in its centre position, both expo values will blink and any entry will adjust the expo equally
both sides of centre. However, if, for example, you hold the stick left of centre, only the left value of
expo will blink, and the keys will change only the left side of the graph and left side of stick travel. In
this way you can have a different expo curve on one side compared to the other.
For each control you can set two switches. For a dual rate arrangement, simply chose the
appropriate switch (say ELE) for DrSw1 and leave DrSw2 blank. To have the switch work in the
reverse direction, choose the “not” form (!ELE).
For a triple rate arrangement you can us two switches. The main switch changes between high and
mid-rate. If the main switch is “low” (i.e., mid-rate) the second switch can then switch between mid
and low rate.
The three position switch (ID0, ID1, ID2) switch can also be used for triple rates. For DrSw1 enter “!
ID2” (remember the exclamation mark means “not”) and for the DrSw2 enter “!ID1”. The logic is that
Sw1 is not ID2 so it must be either ID0 or ID1. Likewise if Sw2 is not ID1 it must be ID2.
Mixer (page 5/13)
This is where you manage the relationship between the inputs (sticks, pots and switches) and
outputs (servos, speed control). In Ersky9x the only predetermined mixes are the basic four channel
setup that is automatically created for every new model, plus templates for some additional mixes,
notably V-tail and Elevon/Delta. All of these can be edited and beyond them you have the freedom to
define exactly what you want the servos to do.
