Trimming the quadcopter
Already shortly before the quadcopter takes off, you can recognize
whether it wants to turn or glide in a particular direction. Correct
the deviations from the vertical ascent with the trim knob of the
turn function.
Tip of the fuselage turns to the right:
• Reduce speed and push the trim slider of the turn function on
the left remote control lever stepwise to the left.
• Push the pitch-lever forward again and check whether the
correction was sufficient, if necessary shift the trim further to
the left.
• Repeat the process until the quadcopter no longer shows a
tendency to turn to the right.
Tip of the fuselage turns to the left:
• Proceed as described above, but push the trim slider of the turn
function stepwise to the right.

Batteries are empty
Charge the batteries or exchange them
The model moves forward/ backward and
sidewise, but does not hover
Check whether the Helicopter is exposed to
a draught, e.g. by an opened window or an
air conditioner. Hover flight is not possible
when there is a draught
Close the window/door, switch off the air
conditioner or select a more suitable room
The model vibrates severely
Check whether the rotors run true
Possibly change the rotor blades
Transmitter and Helicopter can not be
binded
Throttle control not set to minimum
