Back & Forwards, Up & Down:
This helicopter features
counter-rotating coaxial rotors (a fancy way of saying two
rotors which spin in opposite directions) and a horizontal
tail rotor. If you’re any kind of expert on helicopters, you’ll
know that this is not the same way that full-scale helicopters
are usually made – they’ve got a single, uni-directional main
rotor with a vertical tail rotor. We think that this coaxial
design works best for these scale models because:
•
It’s more stable than a single rotor. Because the rotors move in opposite directions, the helicopter
has less of a tendency to spin the other way.
•
It is way easier to set up. There’s only one trim setting to get right, as opposed to the three trim
settings that are required for the more conventional helicopter design.
•
More rotors mean more lift, which means an easier to fly and more manoeuvrable helicopter.
However, because the tail rotor is horizontal rather than vertical, the helicopter has a tendency to
ascend whilst moving forwards, and descend whilst reversing. This isn’t really a problem if you ease off
on the throttle whilst moving forward and increase the throttle whilst moving backwards. You’ll get a
feel for it pretty quick.
To alter how fast the helicopter moves backwards and forwards, use the Tail Rotor
Speed Select Button
on the controller. When the button is pushed in, the helicopter is in SLOW mode. When the button is
up, it is in FAST mode.
Firing Missiles
To load missiles into the helicopter, align the missile with the firing tube on the side of the helicopter,
and push in gently. Don’t be rough - if it feels like you have to force the missile inside then there’s
something wrong - you’ll probably have to rotate the missile so the grooves line up.
To fire the missiles, use the trigger buttons on the controller. The right trigger will fire the right missile,
and vice-versa.
Be extremely careful where the helicopter is pointed whenever missiles are loaded into the helicopter.
The triggers can easily be bumped inadvertently, and the projectiles have a surprising kick, particularly
at short range.
Don’t use the missile functions around other devices which use infrared controllers (such as a remote
controls or computer devices that use IR communications) as there is a chance that another IR device
might cause a spurious control signal, and cause the helicopter to behave erratically or fire the missiles
without warning.
