Once the model is properly trimmed, you can practise hov-
ering, and carry out manoeuvres such as circles, squares,
rectangles and figures-of-eight.
dell
To avoid giving incorrect control commands, always stand
about two metres away from the model, behind it and to
one side.
You can fly a square pattern by alternating the direction
of flight: away from the pilot, to the pilot's right, and then
towards the pilot.
Tip: when the helicopter is flying with the nose point-
ing towards you, the functions are reversed (apart
from the throttle control).
Important Notes
Take-off:
Raise the rotor speed slowly and steadily until the mod-
el is hovering approximately at eye-level. Adjust the trims until the
helicopter is hovering stably over one point.
At low height (approx. 10 - 15 cm above the ground) the model
cannot be trimmed accurately due to the turbulence generated
by the rotor.
Landing
: Slowly and steadily reduce the throttle setting until the
model descends and touches down. Never reduce the throttle
setting abruptly.
After the landing disconnect the flight battery from the receiver,
and only then switch the transmitter off.
Caution:
Blocking (obstructing) the rotor blades when they are
turning can cause serious damage to the mechanical system,
and may even result in a fire. If the rotor is forcibly stopped, im-
mediately move the throttle stick back to Idle!
Note regarding the flight battery:
As soon as you notice a re-
duction in motor power, land immediately and disconnect the bat-
tery. Never continue flying until the battery is flat, as this causes
a deep-discharge condition which results in permanent damage.
Allow the battery to cool down before recharging it.
Replacing the rotor blades:
If a rotor blade is damaged, replace
it immediately. When fitting the new rotor blade, tighten the retain-
ing screw just to the point where the blade still swivels smoothly.
