ADVANCED FLIGHT OPERATION
Before you start to use any of the advanced features of your Gravit,
you should make sure that you are familiar with the basic control
commands of your Gravit and you should be comfortable with flying
the Gravit.
For information on the different flight modes of your Gravit, please
read through the chapter “The flight modes”.
As mentioned in the “Basic Flight Operation” chapter, you can
combine the stick inputs of your transmitter to more complex flight
maneuvers.
When doing so, please keep in mind the following things:
Declining and climbing with your Gravit
When you choose to loose or gain height with your Gravit and lower
or raise the throttle stick, you should make sure that you are doing so
at a reasonable pace.
A quadrocopter does NOT have the ability to “glide” (like a plane), it
cannot fly “by itself”. Therefore, you should always make sure that
your throttle inputs are not too extreme. Whenever possible, increase
or decrease your thrust always smoothly and slowly, NOT abruptly.
This is ESPECIALLY true when declining. When declining, do so at a
slow speed and try to decline while moving, NOT on the spot.
Declining on the spot always bears the risk of getting caught by your
so-called “prop wash”. Think of it like that: Your quadrocopter pushes
air downwards to generate upwards thrust, which is keeping it in the
air. The air which is pushed downwards generates a downward-pull
and turbulences and if you are declining straight downwards into
the downward-pull, your quadrocopter might start to tumble or even
crash.
Taking video footage with your Gravit
When shooting video with the camera of your Gravit, you should
also keep in mind that the way you are flying is SEVERLY impacting
the quality of your video footage. No matter whether you own and
fly a Gravit version WITH gimbal (#220721) or WIHTOUT gimbal
(#220720), you should always consider the following points in order
to get the best possible image quality from your camera:
1) Whenever you move your Gravit in any direction, do so slowly
and smoothly.
2) Do not constantly change your direction of flight, as this will result
in “nervous” and unsteady video footage
3) When shooting a longer scene while flying in the same direction,
make sure you are flying with the wind in your back, not against
your Gravit.
Retain your orientation
Since your Gravit is a symmetrical object, it is more difficult to tell
its orientation in the sky compared to an airplane, for example.
Your Gravit is equipped with very bright LEDs on the bottom side
of each arm. The front LEDs have green color, the rear LEDs have
red color.
Keep this in mind in case you should loose control over the orien-
tation of your Gravit.
When you are too far away or when flying in very bright daylight
(against the sun), you will notice that the LEDs are not visible any
more.
If you happen to loose control over the orientation of your qua-
drocopter, do NOT panic. There are several things you can do to
regain your orientation again:
1) The easiest way is to flick the SWA switch of your transmitter to
the lowest Pos. 2. This will initiate a return-to-home. The Gravit
will fly towards its take-off position and then attempt to auto-land.
You can use this feature to bring the Gravit back into a clearer line
of sight and when you regained orientation you simply cancel the
return-to-home by flicking the SWA switch back to top position.
Then you can continue flying normally again (please also read
chapter “Landing your Gravit”).
2) It is also possible to regain orientation by flying a certain maneu-
ver: Fly a rather BIG circle by moving throttle upwards and either
pushing the right control stick to the left or right (depending on
which direction you want the circle to be flown). When the Gravit
is starting to fly the circle, you will come to the point when the
Gravit is flying ROUGHLY towards your direction again. At this
point, let go off the right control stick and let the Gravit fly straight
ahead. After a few seconds, repeat this maneuver. You can
attempt to fly a smaller circle now and you can also change the
rotation of the circle this time. By doing so, it should be possible
to fly the Gravit closer and closer back to you until you finally
regain your orientation again and fly the Gravit normally.
When loosing control
In case you should ever loose control over your Gravit (maybe as
a result of a failed maneuver or a gust of wind), let go off the right
control stick and apply full (or near full) throttle. The reason for doing
so is quite easy:
1) If you let go off the right control stick, the Gravit will stop any ho-
rizontal movement/acceleration and stabilize itself automatically
2) If you apply throttle, this will also help to stabilize the Gravit and
the Gravit will fly upwards
That is normally a good thing, as
there are no obstacles in the sky, but many on or near the ground.
So both actions will help your Gravit to stabilize and fly out of the
danger-zone (which is usually near the ground, NOT up in the skies).
Then you can regain control again and continue flying.
