Mount your propellers
The propellers of your Gravit GPS are self-tightening propellers
which can only be mounted in one direction. This is a security
feature which prevents the props from being mounted onto the
wrong motor(shaft).
To do this correctly, please have a look at the propellers.
You will see that the propellers are bearing symbols. Those
symbols show you in which direction the propeller is locked
(closed lock icon) and unlocked (open lock icon). The propel-
lers are always mounted in a way that the locking direction is
CONTRARY to the motor rotation direction (which is imprinted
on each arm of the copter near the motor).
For example: If you have a motor which is rotating clockwise
(as indicated by the arrow on this motor‘s arm), then you have
to use a propeller which locking-direction is counter-clock-
wise, and vice versa.
To mount the propeller, just set it on top of the motor-shaft and
rotate it into the appropriate direction until it is fully seated.
The propeller will tighten itself when the motors are started,
you don‘t need to tighten it up manually.
Check the screws on regular basis
During flight operation, your Gravit is in constant movement
and the screws might become lose as a result of this motion,
vibration and strain on the components. This is especially true
for the four screws that hold each of the four motors in place.
Please check the screws on a regular basis. Take special care
of the motor screws and make sure that they are always suffi-
ciently tightened. Also, make sure to tighten the motor screws
in a way that the motor will not grind against the plastic arms
surrounding it. You can check this by manually spinning the
motor with you hand.
Do NOT overt-tighten the screws by using too much force, just
make sure that they are snug.
ATTENTION! Check wireless status of your Gravit’s camera
The wireless action camera of your Gravit is also capable of
2.4 Ghz wireless operation. This functionality is used for trans-
ferring pictures and movies from the camera to your smart-
phone or for configuring the camera via smartphone app.
However, please be aware that the 2.4 GHz signal of the wifi
action cam may interfere with the 2.4GHz signal that your
transmitter is using to operate your Gravit.Therefore, we
STRONGLY ADVISE NOT TO ENABLE the wireless function
of your camera while flying your Gravit. You can enable and
disable the wifi function of your camera by holding down the
“OK” button on top of the camera for a few seconds when the
camera is switched on.
Since the “OK” button of the camera is also used for other
purposes (mainly starting and stopping a recording), please
make sure not to enable the wireless function of your camera
ACCIDENTALLY by pressing the “OK” button for too long.
For a more detailed explanation of all function of your came-
ra, please read the appropriate chapter „The camera“ in this
manual.
