6.3 Hovering and Cyclic Trim
Because your helicopter’s rotors create a ‘downdraft’ any
attempt to hover at too low an altitude (height) is more
difficult than hovering a little higher. This difficulty is
because the downdraft from your rotors is bounced back off
the ground, resulting in turbulent air around the
helicopter-this is referred to as ‘Ground Effect’. For this
reason, we recommend that you begin your hovering
practices at about 1 meter off the ground.
1. Keeping a safe 1 to 2 meters from your model, S-M-O-O-T-H-L-Y advance the
collective Throttle joystick until your helicopter reaches approximately waist height.

2.If the helicopter has a tendency to rapidly move in any direction, either:
a.LAND IMMEDIATELY, by S-M-O-O-T-H-L-Y reducing the throttle power. Then
adjust the trim sliders to compensate. Repeat the sequence from Step1, above.
b.GENTLY apply cyclic joystick correction in the opposite direction to the
helicopter’s aberrant movement. Once you’ve established the amount of required
control correction, land your helicopter. Adjust the trim sliders equivalent to the
amount of the applied joystick compensation. Repeat this sequence, beginning at
Step1, above.
3.GENTLY and S-L-O-W-L-Y push forward/pull back on the collective Throttle to
maintain an even height without ‘bouncing’ the helicopter up and down.
Tip: for more sensitive control-and improved ability to mix Throttle and Rudder
inputs-try placing your left thumb on the tip of the collective joystick.
4.S-L-O-W-L-Y reduce the Throttle power and GENTLY land your helicopter.
5.Repeat the exercise, from Step 1 until you can confidently lift, hover and land your
helicopter under full control.
