C) Adjustment Of The Neutral Position - Reely 450 ARF QC09 Bedienungsanleitung

c) Adjustment of the Neutral Position

For the stabilisation of the QuadroCopter to work correctly, the neutral position must be set. This is the position that the
QuadroCopter tries to stabilise as long as no other flying manoeuvre is desired.
Proceed in the following sequence:
1) Switch on the transmitter.
2) Set THROTTLE to zero and all other levers and trims to the neutral position.
3) Place the QuadroCopter on a level, even surface.
4) Connect the rechargeable battery to the QuadroCopter.
5) The QuadroCopter's red LED must be off and the green LED must be lit.
6) Move THROTTLE to full deflection and YAW
to full deflection on the right (figure 18).
7) The QuadroCopter's green LED flashes as confirmation and the neutral position is memorised.
8) Move the THROTTLE back to 0, move YAW, PITCH, and ROLL into the neutral position.
9) The red LED is off and the green LED must be lit. Now your QuadroCopter is ready to start.
If you do not set the neutral position, the QuadroCopter will use either the factory settings or the last saved value!
It is very important that you set the neutral position of the QuadroCopter as precisely as possible. For this,
it is necessary to set the neutral position on a completely horizontal base. Ideally, this should be measured
with a spirit level.
It is therefore urgently recommended that you set the neutral position before first flight. Due to different environmental
conditions than in the factory and/or at the actual place of flight operation, the factory setting may not be ideal!
If the QuadroCopter still swerves in one direction despite the relevant trims to the transmitter, the neutral position must
be stored again by slightly lifting up the QuadroCopter on the side to which it swerves. This way, the (changed) position
is saved as the new centre position.
