Ground Effect; Free Flying Training - Carson Airbeast II Pro Instruction Manual

i. Ground Effect
GB
ATTENTION!
Up to a height of about 30 cm, the
model is in the area of influence of
the air turbulence caused by its own
rotors.
On one hand, this "ground effect" facilitates the lift off
of the helicopter since the air pressed downwards by
the rotors of the helicopter helps lift the aircraft from
the ground.
But in the immediate area this effect is reversed, since
the air flowing away laterally from the helicopter
creates an underpressure and the model is actually
sucked back down towards the ground. This can lead to an
ungentle landing.
For this reason the flight behaviour of the model at low heights is
rather unstable. If the restless flight behaviour causes
difficulties for you, increase the flying height by degrees.
j. Free Flying Training
The helicopter is no longer in the area of influence of the air
turbulence from its own rotors as of a flying height of about 2 m and
the flight situation is more stable.
If you have mastered hover flight, begin with
simple flying formations:

Free flying training

• When you feel secure, stand laterally to the model and practice
control from this angle of view or
• Allow the model to fly toward you and control it in the opposite
direction.
• Avoid jerky load variation, since otherwise the upper and lower
rotor could touch and cause the model to crash.

Train your command of the model, allow it to ascend and descend,
hover and move forwards and backward in the air as well as execute
turns.
• Always fly the model in front of you or allow it to circle above you.
If you allow the model to fly behind your back, you could lose your
orientation and thereby the control over the helicopter.
Never attempt to catch the model in mid flight!
