Programming example - fi xed-wing model
The remaining options in the “Fixed-wing mixers” menu
are designed to provide further fi ne-tuning of multi-fl ap
wing systems, and are largely self-explanatory.
When you have completed the model-specifi c settings
up to this point, you are probably ready to consider the
model’s fi rst fl ight. At this juncture you should certainly
take the time to carry out a series of “dry runs”, i. e.
check all the settings thoroughly while the model is still
on the ground. Remember that a serious programming
error may damage more than just the model. If you are
not sure of any point, please ask an experienced model
pilot for advice.
If during the test phase you realise that one or other of
the settings needs to be changed in order to tailor the
model’s control response to your preferences - perhaps
the servo travels are too great or too small overall - then
we suggest that you turn to the …

… in order to adjust the overall set-up to suit your
requirements and fl ying style.
The Dual Rate function is used to adjust the relationship
between stick travel and control surface travel (see page
82). However, if it is only the model’s control response
around neutral which is too powerful for comfortable
fl ying, i. e. the maximum travels are acceptable, then
“Exponential” can be employed, either instead of Dual
Rates or in addition to them. If a physical switch is as-
signed to this function, you can switch between two Dual
Rate / Expo settings while the model is fl ying.
