PROFI mc 4000 for helicopters
- 1 -
Dear customer,
Dear fellow modeller,
This supplement to the PROFI mc 4000 manual has
been specially prepared for model helicopter pilots.
We have sub-divided it into the following sections:
1. The MULTIPLEX Concept
This section provides basic information about
model memories, flight modes and mixers, and
about the methods we use to control the throttle
function in helicopters.
2. „Creating“ a UNIVERSAL helicopter
This section describes the complete basic pro-
gramming procedure required to operate a typical
model helicopter, in this case with 90° mechanics.
If you use one of the pre-programmed base types
everything is actually the same apart from the
servo assignment process.
3. How things work ...
This section includes detailed information on the
How’s and Why’s of the individual functions.
Sections 1 and 3 are therefore for background reading
or reference.
In Section 2 you can actually follow and emulate the
steps using your transmitter. It includes many ideas
and principles which you can adopt straightforwardly
to suit the other variants of helicopter mechanics now
in common use.
Requirements
The procedures and menus described assume that
you are using Version 2.0 of the software.
We have made every effort to describe the program-
ming steps as completely and thoroughly as possible,
but at some points there is really no option but to refer
back to the standard manual. A good place to start
here is to read the section entitled „Quick-start: your
first helicopter“.
And one request to you:
There are bound to be things in this supplement to the
manual which could be improved, such as assump-
tions which may not apply, or matters which we have
simply overlooked. You can help us to improve these
instructions further by letting us know your impres-
sions, experience and ideas for improvements, and
we would appreciate your comments.
Yours – the
MULTIPLEX
