Adjusting The Rotor Blades; Ground Effect - Carson mini tyrann Betriebsanleitung

f. Adjusting the Rotor Blades
Checking the rotor blades
The rotor blades must be able to align themselves 180° to each other
purely by centrifugal force. Before flying the helicopter, you should
therefore check the blade retaining screws. When the screws are
tightened, the rotor blades should still be able to fold downwards
when you tip the helicopter on its side. If the rotor blades are too tight
or too loose, this could result in unstable flight behaviour.
g. Ground Effect
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.
Warning!
The trim levers on the transmitter may get misaligned during
transport. Please adjust the trim of the transmitter to the model
properly before every flight.
