Carson Electric dual-rotor helicopter RtF (500507041) 500507041 数据表

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.

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.

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.

•   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.

•   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.
