g) Control Using the Position Sensors of your Smartphone
Smartphones have position sensors, e.g. to turn the display to make the contents legible or recognisable no matter
how you hold your device. The quadrocopter can be controlled using these sensors in the control functions "nod"
(forward and backward) and "roll" (to the left and right).
In order to control your model with the position sensor, you first need to make all the starting preparations described in
chapter "Control with the Operating Elements of the App". When this has been successfully completed, push the radio
tower icon (figure 15, item 6) until it lights up. Control via position sensors is now activated.
Hold the Smartphone horizontally in both hands. Last, push the "Auto-Start" symbol again (figure 15, item 14). The
quadrocopter will start up at once and float in front of you. Continue to control height and turn around the vertical axis
with the left control element in the display (figure 15, item 12).
Floating to the left/right and forward/backward is no longer controlled with the right control element now, but via the po-
sition sensors in your Smartphone. Tip the Smartphone forward to make the model drift forward. Tip the Smartphone
backward to stop the forward movement or make the model drift backward. Tip the Smartphone to the left to make the
model drift left. The flight direction will be according to how you hold your Smartphone.
