| There are two versions of Alien
Command, the Standard and Advanced. This is necessary due to the
different types of swash plates and mixing systems used by
different helicopters.
Basically, the cheaper
standard Alien Command works great with the standard 90
degree swash plates used by almost all helicopters that are
designed with mechanical mixing systems.
The Alien Command
Advanced system has been introduced to handle the more
common 120 degree swash plate designs used with
electronic mixing systems (CCPM), as these are a little more
complex to control for any auto pilot system.
The
typical store cost of the Alien Command systems alone are : Standard
- £60.00, Advanced - £123.50
My
prices offer attractive savings on the prices above.
I strongly recommend
that all new pilots should have Alien Command fitted to
their helicopters when they first start to learn to fly
them. It provides you with peace of mind and security,
and will certainly save you money in the longer term due to
less crashes and the consequent repair bills.
RETRO FITTING
Alien Command to your helicopter
I am happy to offer a
very low cost service to retro fit Alien Command to your
helicopter. I will supply the relevant system to match
your particular helicopter's configuration, and then set it
all up for you. If you wish, I will also perform a full
mechanical setup on your helicopter before fitting the Alien
Command.
MY charge for supplying
and fitting the Alien Command Standard version is only
£57 + £35 = £92,
and for the Alien Command Advanced it is £117.50 + £55 =
£172.50. These costs include resetting your radio up
correctly to work with AC.
If you would like me to do
a full check plus mechanical setup of your
helicopter as well, just add a further £15.00
In all cases, the
Alien Command system will be fully configured for your
helicopter, and it will then be test flown by myself to
ensure that the helicopter flies correctly with and without
the Alien Command system in operation.
NB - Both versions of Alien Command
can be used with digital or analog servos, despite other
publications stating that they cannot handle digital servos
For more information,
or to book your heli in with me to have your helicopter
equipped with Alien Command and properly setup, please email me or you can call me on my

THE COMPETITION
Naturally, there are
other makes of auto pilots available, the best known of
which is probably HeliCommand, which is an equally great
system, but quite a bit more expensive, and less easy to fit
to a Pod and Boom style Helicopter due to the size and shape
of the sensor.
However, HeliCommand
does add a new function to the auto pilot mix, that of also
maintaining position if possible. It does this by sensing
the ground below, and tries it best to maintain station over
that same point if you let the cyclic stick go.
The other clever trick
the top of the range Helicommand RIGID offer is what is
called blade phasing, which means it electronically varies
the point where multi blade heads (more than 2 rotor blades)
start to change pitch to handle roll and pitch. This is only
required if using flybarless and multi blade heads,
typically on scale machines. |
