RACE-QUADROCOPTER
Here is an example:
Let‘s say that you are piloting your Gravit straight forwards by pushing the right con-
trol stick upwards. The Gravit will tilt forwards and fly into the appropriate direction.
However, if you now let go off the right control stick, the Gravit will NOT neutralize its
angle of attack and return to horizontal level, it will CONTINUE TO FLY AT THE SAME
ANGLE OF ATTACK. If you want to stop the Gravit from moving (= if you want the
Gravit to regain a horizontally level orientation again), you have to COUNTER the actual
angle of attack by moving the right control stick to the opposite way of the Gravit‘s
current angle of attack. In our example, this means you have to move the right control
stick DOWNWARDS (below the neutral position) to have the Gravit reduce her angle of
attack and to finally regain a horizontal orientation again. BUT BEWARE: If you push the
right control stick DOWNWARDS for too long and/or too far, the Gravit will tilt towards
a backwards direction and the game begins again. Flying the Gravit in ACRO-MODE will
require constant stick input to get the copter where you want it and SHOULD BE USED
BY EXPERT PILOTS ONLY!
2) NO MAXIMUM ANGLE OF ATTACK:
This means that the flight controller is NOT limiting the maximum angle of attack that
the Gravit may obtain when the right control stick is FULLY deflected into any direction.
In the other flight modes, it is NOT possible to fly a real looping, for example. The rea-
son for this is that if you want to fly a looping, you need the Gravit to be able to fly and
rotate without any limits, even upside down for a short moment.
In normal mode, this is not possible. The flight controller limits the maximum angle of
attack, thus your Gravit will not be able to fly a looping (only flips are possible in the
flipping mode). It will fly upwards at a certain maximum angle, but it will not constantly
increase the level until it flies a looping. Whether you are flying a „real“ looping or just
doing „flips“ like in the flipping mode depends on the combination of throttle and angle
of attack that you are applying to the Gravit. For example:
- Moderate throttle and moderate deflection of the right control stick will result in a
looping with larger diameter
- Full throttle and maximum deflection of the right control stick will result in a quick
series of flips (with very small radius) into the appropriate direction.
-> This means that the diameter and speed of the flips/loops results from the combina-
tion of the amount of thrust and the level of deflection applied by the right control stick.
ACRO-MODE lets you do the funniest, coolest and most difficult of flight maneuvers,
but WE STRONGLY RECOMMEND TO ONLY USE IT WHEN YOU ARE AN EXPERIEN-
CED PILOT.
IMPORTANT: In case you should loose control over your Gravit while flying it in
ACRO-MODE, please quickly switch UP the S3 switch again. You will be in one of the
stabilized flight modes AT ONCE. Let go off the right control sticks until the Gravit has
stabilized and is horizontally orientated again.
Even though the Gravit is able to recover very quickly when switched back from
ACRO-MODE, you should still make sure that risky flight maneuvers should be only
flown at a height of over 30 meters. By doing so, you give your Gravit enough time to
recover from a piloting error and to stabilize to a horizontal position again. Please also
be aware of the fact, that a crash is much more likely to happen in ACRO-MODE and
that you could damage your Gravit.
The 5.8 GHz-FPV-system of your Gravit Xtreme (5.8 Ghz-camera and LCD-receiver)
Your Gravit Xtreme is ex works equipped with a HD-5.8Ghz-FPV-system. This system
does not only allow you to fly your Gravit FPV (=First Person View) via the LCD-receiver,
but you can also record videos using the camera‘s integrated Micro-SD card slot.
The range of the FPV-system is around 100 meters. However, due to environmental in-
fluences and interferences (like power poles, other radio signal or obstacles like trees,
etc) the range can be reduced drastically. So please carefully check the range in your
flying area.
This chapter will cover all the functions and features of your FPV-system in detail.
1) The 5.8GHz camera
The camera comes already pre-installed and wired. In case you don‘t want to use the
camera, it can be unplugged and detached from the chassis of your Xtreme 80 easily.
One reason to detach the camera for example might be that you want to extend your
performance and flight time to the maximum and do not really need a camera. In this
case, detaching the camera can help you. Without the camera, the Gravit is lighter and
the lipo will last longer because it does not have to provide power to the camera. Both of
these facts will lead to higher speed, better overall performance and longer flight time.
If you re-attach it, just make sure to fit the camera correctly and firmly back into place and
also make sure that you connect the camera correctly to your chassis (see picture). Also
make sure, that the antenna coming out of the rear of your camera‘s chassis can swing
freely and is not jammed or obstructed.
Please note:
Connecting the camera plug reverse-polarity may result in the damage or
destruction of your camera and the electronic board of your Xtreme, so always make
sure to connect the camera correctly!
Before using the camera, plea-
se insert the Micro-SD card
which has been provided with
your Xtreme like shown on the
picture. You may also use a
3rd party Micro-SD card, but
LRP does NOT give any com-
patibility guarantee, so please
feel free to experiment here on
your own risk.
In order to use the FPV-system,
make your Xtreme ready to fly,
then turn on the attached LCD-
receiver. In case you have not
yet installed the LCD-receiver
to its mount on the TX, please
do so now. Also make sure you
have unfolded the integrated
sun-shield of your LCD-mo-
nitor, so that you can see the
screen freely. Within a few se-
conds, your Xtreme will be ready to fly and the LCD-monitor will show a live video image
of your camera. Move around the Xtreme to check the correct video transmission.
The LCD will show a red dot followed by a time code in the lower right corner of the
screen. The time code shows the hours, minutes and seconds that are still left on your
Micro-SD-Card.
The number given here may vary, depending on the capacity of the card you are using
and on how much of the capacity is still available for recording. The provided 4 GB Micro-
SD-card should provide a recording time of ROUGHLY 1 hour and 10 minutes if the card
is empty.
In case you receive a red message in the middle of the screen saying „MEMORY FULL“,
this can either mean that your inserted Micro-SD card has not free available space any-
more OR you have not inserted the a memory card at all.
If a memory card with free space IS inserted and the warning is showing up nevertheless,
this means that your memory card is either not compatible with your camera or has not
been formatted properly. In this case, either change or reformat the card, using the FAT32
file system.
Starting and stopping a recording
To start or stop a recording, simply press the RED BUTTON on the upper left corner of
your TX (RIGHT to the S2 switch). The red dot in the right lower corner of the LCD will
start to flash and the color of the time code will change from white to red and count the
number of time the recording is already running. Press the red button again to stop the
recording. The red dot will stop to blink, the time code will turn white again and the time
shown on the display is now the updated time which is still left for recording.
Using a recording on a PC or Laptop
The recordings are saved as „AVI“ files on the SD-card. To watch and edit those movie
files, simply insert the Micro-SD card in the provided card-reader and insert the reader
into a free USB-Port of your PC or laptop. The Micro-SD card will show up as an exchan-
geable data device (just like an external hard drive or a USB-memory-stick) and you can
browse it by using the file browser of your operating system (which can be Windows XP
or higher, as well as MacOS or Linux). On the Micro-SD card, you will find a folder called
„DCIM“. Inside this folder is another folder called „100DSCIM“ and inside that folder are
your video files, named „PICT000X.AVI“, where „X“ is the number of the movie. You can
now copy, edit, delete or watch the movie as you like.
2) The LCD-Monitor
The LCD monitor is pretty much plug and play, you don‘t have to make any adjustments
or settings, UNLESS you want to fly with other pilot using the same equipment. In this
