17. The First Flight
Important!
Before switching on the transmitter, please set the throttle stick to “motor off” and all trim levers of the pilot
stick to zero (mid trimming). Otherwise, the QuadroCopter may not recognise the transmitter after the
battery is connected.
Switch on the remote control. Then connect the flight battery. The QuadroCopter then performs a short self-test after
which the green LED is permanently lit. In case of an error, the LEDs flash. If an error occurs, the rechargeable battery
should be disconnected and connected again after the error is eliminated (e.g. throttle not in zero position). In case of
an error, the motors cannot be started again for safety reasons.
Please ensure that the QuadroCopter stands as levelly as possible when the rechargeable battery is connected. Until
the green LED lights up, all sensors are being internally aligned and the QuadroCopter should not be moved during
this time. If the place of take-off is uneven, it is recommended that you level out the surface and save the neutral
position through full throttle/yaw right (see chapter “set neutral position”).
Start the motors (with throttle on zero, yaw left) and let the motors run at idling speed. Check the running of the rotors
once again. All rotors should run smoothly on one level without the QuadroCopter vibrating. If a motor does not start,
turn the motors off again and move the rotor of the non-starting motor to a quarter rotation with your hand. Then start
the motors again.
Ideally, now slowly increase the speed of the rotors (the throttle) of the QuadroCopter until you can see a slight
increase of altitude. Test the roll and yaw directions just before the QuadroCopter starts to hover to ensure that the
transmitter is correctly set and there is no channel inverting (control signals are reversed). Generally avoid any fast
and big controlling motions. Also watch closely to see whether and in which direction the QuadroCopter moves. By
using trimming on the remote control, you can prevent undesired movements.
Important!
Never take off with a badly trimmed flight device.
Then increase the throttle until the QuadroCopter is at least one meter above the ground. Carefully try to correct a
gentle drift with the trim levers for yaw, pitch or roll.
As soon as the QuadroCopter is high enough in the sky, decrease the throttle until the QuadroCopter hovers. Now you
have managed the critical part and can slowly and carefully better familiarise yourself with the throttle controlling
motions of the QuadroCopter. To land the QuadroCopter again, decrease the throttle slightly until the QuadroCopter
gravitates to the ground. A somewhat solid touchdown on the ground is no problem and should not be corrected with
jerky throttle movements.
Try to touch down where possible in vertical position (“helicopter landing”). Avoid landing with high horizontal speeds
(“airplane landing”). After landing, turn off the motors (press throttle stick to the bottom right).
Practice this starting procedure a few times to get a feel for the QuadroCopter . As soon as you are reasonably sure,
you can begin to steer the direction with yaw, pitch and roll. Always steer slowly and carefully and practice the proc-
esses a little before trying a new flight manoeuvre. The first flights should not last longer than 30 to 60 seconds each.
