X-3D-BL User’s Manual
4 Operation of the X-3D-BL
4.1 Important things to keep in
mind
•
Directly after turning the X-3D-BL on the
motors produce a short beep. It is perfectly
normal that the propellers move slightly during
that tone.
X-3D specific hints:
•
Keep the X-3D-BL totally still after turning it
on until the X-3D shows the green (no
reception) or green (ready to fly) light pattern.
Otherwise the sensors can not be calibrated
correctly and the vehicle might go crazy after
turning on the motors. If you accidentally moved
the system during startup simply turn it off and
on again.
•
If only the green LED at the X-3D board is on
the vehicle is ready to fly. A green light
pattern means ”no reception”, which is also
signalized by a periodic beep of all motors. In
this case please check that your remote control is
turned on and fully functional, that the receiver
crystal is installed in the receiver and that the
receiver is connected correctly.
X-3D-FunPilot specific hints:
•
Keep the X-3D-BL totally still after tur-
ning it on until the X-3D shows the yel-
low(blgreen+red
(no
reception)
or
yellow(blgreen (ready to fly) light pat-
tern. Otherwise the sensors can not be calibrated
correctly and the vehicle might go crazy after
turning on the motors. If you accidentally moved
the system during startup simply turn it off and
on again.
•
The red LED after the initialisation phase means
”no reception”. Check your RC transmitter, the
crystals and the receiver.
Hints for X-3D und X-3D-Funpilot:
General hints:
•
After the startup phase the motors are still turned
off and secured. To turn them on you have to
move the yaw stick to the very left or to the
very right while your throttle stick is in zero
position. The motors will then start and keep
running at their minimum speed. Now you can
fly as usually. To turn the motors off you have
to do the same procedure again: Move the yaw
stick to the very left or to the very right while
your throttle stick is in zero position. There is no
flight maneuver where one would use this con-
trol input and thus you will not accidentally turn
off your motors during flight. For safety reasons
you should turn off the motors immediately if
one of the propellers touches the ground or any
other obstacle and hence the X-3D-BL is not
able to take off.
•
There is a battery warning implemented in your
X-3D-BL. A low battery is signalized by a pe-
riodic, simultaneous tremor of all motors. This
is hard to see but it can be heard. Depending on
the battery you use there is about a minute of
flight time left after the low-battery warning is
activated. Lithium Polymer (LiPo) batteries are
very vulnerable to deep discharge. That is why
the X-3D-BL turns off completely if the volta-
ge drops under a programmable threshold. You
can adjust the thresholds for the low-battery war-
