the movement will be.
Of course, all of those maneuvers can be combined together
to more complex flight maneuvers, like for example flying a
circle, or flying up and forward at the same time.
IMPORTANT:
As soon as the battery of your Gravit is depleted
beyond a certain voltage, the status LED of your Gravit will
start to blink red very quickly. It is now time to bring your
Gravit back home.
Keep an eye on your status-LED
While flying, always keep a close eye on the status-LED of
your Gravit.
The status-LED will tell you anytime if everything is ok and
which flight mode you are currently using. For a detailed listing
of all the status codes, please see chapter “The Gravit GPS,
The Status-LED”.
There are 3 status codes, which should specifically catch your
attention and which require appropriate actions to be taken:
1)
Low-voltage-warning
If the status LED is starting to emit a series of fast, red
blinks, then your LiPo is beginning to become depleted. You
should slowly start to land your Gravit without any further
delay (see chapter „Landing your Gravit“).
PLEASE NOTE:
It may happen that the low-voltage-
warning is kicking in to early if you fly maneuvers that put
a lot of strain on the Gravit’s propulsion. For example, if
you hover in the air and the suddenly apply full throttle, the
low-voltage-warning may kick in shortly, although you are
still good to go for a while. In this case, you may continue
to fly. But watch out for the low-voltage-warning at any
time and if it is constantly showing up, it is about time to
bring your Gravit back home.
PLEASE NOTE:
Depending on the flight mode you are
using at the moment the low-voltage-warning is triggered,
the Gravit behaves differently: For BALANCE and ALTITUDE
mode, the Gravit will CONTINUE to fly until the second low
voltage warning kicks in. When flying in GPS-mode, the
Gravit will instead initiate a “Return-to-home” and fly back
to its take-off position. When the second warning kicks in
for BALANCE and ALTITUDE mode, the Gravit will either
return to home OR auto-land, depending on your software
settings (see chapter “Software”).
2)
Compass error
Whenever your compass is not working correctly, the
status-LED will give out long yellow blinks.
When you receive this warning code, do not panic. During
flight, especially when flying very tight and fast maneu-
vers at high speed, it might happen that the compass is
SHORTLY “out of bounds” and the status-LED comes up
with a yellow warning signal. In this case, stop your Gravit
in the air and watch the status-LED. Most likely, it will stop
to give out the yellow error code within a second or two
and you can continue to fly.
Only in case the yellow warning code is continuously (or
repeatedly) showing up, you should ground your Gravit and
check your compass (see chapter “Compass calibration”).
3)
GPS-error
As soon as you notice two short, intermittent RED blinks
on the status-LED of your Gravit, beware. This means that
your Gravit has lost full satellite lock and you cannot use
any flight modes that rely on GPS-assistance (like return-
to-home, GPS-mode, and others).
IN CASE you are NOT planning to use any GPS-assisted
flight functions, you may continue to fly without any wor-
ries. However, we do NOT suggest doing so, as the return-
to-home and fails safe feature of the Gravit are also NOT
working in this condition. So keep in mind that you are
flying at your own risk while not having full satellite lock.
