• The current calibration becomes more accurate when the nose
of the copter points either the west or east direction, because
then slight deviations can better detected.
• Furthermore, the suspension position must first be determined
and remembered before, if necessary, the propellers are
reversed and mounted vice versa, so that the copter is pressed
to the ground instead of lifting.
• During the current calibration, the copter must not move and no
other control sticks may be moved during the calibration except
for the throttle stick.
Current calibration step by step
1. Move the throttle / pitch control stick to the idle position and the
motor ON / OFF switch S1 to the motor OFF position.
2. Bring the angle " " on the left edge of the display to the "CUR-
RENT CALIBR." line.
3. Push the ENT key to activate the value field.
The value field is displayed inverted:
4. Change the value field to "Yes".
5. Push again the ENT key.
The value field is again displayed as "normal".
6. If "CURRENT CALIBR." is displayed in the value field of the "CUR-
RENT CALIBR." line, the switch S1 must be brought to the motor
OFF position if necessary.
7. If "Min" is displayed in the value field of the line CURRENT CALIBR,
switch S1 must be switched to the motor ON position.
8. If in the value field of the line "CURRENT CALIBR." "hover" is dis-
played, the throttle / pitch control stick must be brought into the
hover position.
Note
If the copter has rotated by mistake or by a command during the
current calibration, the calibration must be repeated.

With this option, if necessary, the basic calibration of the accelera-
tion sensors can be readjusted, so that the copter hovers with the
control stick and trim to neutral, in attitude mode, precisely horizon-
tally.
To recalibrate, place the copter on an absolutely horizontal surface
and then set the value field to "YES".
As soon as the calibration is completed, the display changes back to
"NO". To accept the calibration that has just been carried out in the
non-volatile memory of the receiver, it is essential to push or tap on
the ENT key.
