5 - mode switches
Put switches SWB/SWA to 0-0. I think 1-0 is manual mode too. In this
mode you can unlock the motors. Flying is fully under your own
control: no GPS assistance whatsoever. The quadcopter will drift. The
throttle acts in a simple (absolute) way: down will shut stop the
motors, up will max out the motors.
Put switches SWB/SWA to 0-1. First SWA to 1, then SWB to 0. This is
the 'stable' mode. You need to unlock the motors first in manual mode,
but you can lift off in this mode. you also need to have GPS lock
(green light on) for this mode, so wait for the green light to stay
on. If you go to this mode while flying, first put SWA to 1, then SWB
to 0. The throttle now acts in a 'smart' way: the middle position
means 'keep the current height'. The remote will beep as a feedback
for this middle position. To raise, have the throttle above 50%, to
lower, the throttle must be below 50%. The quadcopter will lift up
only when the throttle is over 50%.
One-key return mode
Put switches SWB/SWA to 0-2. First SWB to 0, then SWA to 2. Preferably
switch to Positioning/Stable mode first, and check stable flight. For
this mode, you need GPS lock (green light on). It is also neccesary
that you had GPS lock while unlocking motors! Now the quadcopter will
first raise to 15 meters (if it is lower). Then it will cruise back to
the starting point in a straight line and at it's current heigth. Make
sure the throttle is down, or it will not land. After landing, the
motors will stop and be locked. For unlocking, go back to Manual mode
Put switches SWB/SWA to 1-1. First SWA to 1, then SWB to 1. Now, the
front of the quadcopter is assumed to be pointing the way it was when
unlocking, and the steering will act accordingly. This mode is not
adviced for non-experienced pilots.
Put switches SWB/SWA to 1-2. Take off in SWB/SWA 1-0 mode, then switch
SWB to 2. You can still change height with the throttle, but if you
set it to 50% (with the transmitter beeping), it will stay there. I
think this is Positioning mode for heigth only, Manual mode for the
This mode will be entered automatically when the quadcopter loses the
control signal of the remote. E.g. when flying out of reach. Obviously
this can be forced by switching off the remote. The quadcopter will
return to starting (unlocking) position, as in One-key return mode.
#### What would happen if, while activating this mode, or while
unlocking, there was no GPS lock? ####
Return from Safe-fail return mode
When the quadcopter is cruising back, and the control signal is
restored, you can exit in one of two ways:
If the Safe-fail return is started while SWA is 0 (Manual mode):
Put the throttle in the middle; put SWA to 1; then put SWA to 0; now
you have control again.
If the Safe-fail return is started while SWA is 1 or 2 (Positioning,
Non-Nose, Height-setting modes):
Put the throttle in the middle; put SWA to 0; then put SWA to 1; then
put SWA to 0; now you have control again.
