Safety

A MikroKopter is not a toy. The safety instructions are intended not only for the protection of the aircraft, but also to protect your own safety or others. Improper operation can cause serious injury and property damage.

We do not guarantee error-free behavior of the electronics or software. Despite careful preparation and review, we do not assume any warranty or liability (direct or indirect) for the accuracy of the software, hardware or information. Use the electronics on your own risk (this also applies to associated computer programs). Furthermore, we assume no liability for consequential damage to property or persons caused by the application. It is your responsibility to perform a full system test.

In case of improper use a MikroKopter can be dangerous. Do not fly over people! You need an appropriate insurance before the first flight, as required by law in many countries!

The rotating propellers can cause serious injury. Make sure that children and other persons don't get too close to a powered MikroKopter.

General

A MikroKopter is not a toy and not suitable for children under 14 years
If you don't have sufficient knowledge about the control of a model aircraft, please contact to someone with experience
An appropriate (model aircraft) liability insurance is required. In general, model aircraft are not covered by a standard liability insurance.
The electronics must not be wet and should be operated in the temperature range of 0-40 °
Refer to the Wiki and forum about the features and operation of the MikroKopter

Before starting

Check the reliability of the MikroKopter.
The flight battery and transmitter battery must be fully charged
Always turn on the transmitter first and then the MikroKopter
Watch for visible damage such as for loose screws, broken, unbalanced or damaged propellers, faulty connectors or solder joints, broken pipes, etc.
The propeller must be in a good condition and securely mounted. The rotors must spin smoothly and there shall be no objects are in the rotational plane of the propellers and can get into it. Rotating propeller ends are dangerous to touch - never touch with fingers and other body parts a rotating propeller.
Ensure the appropriate to the audible beeps when auto lipo-detection is enabled. 4 * beep means 4s Lipo
Ensure that the channel of the remote control is free and you're within range of the transmitter
The sensors must be calibrated (When the motors are off: move yaw- and gas stick into upper left corner until it beeps)
Different settings can result in fundamentally different flight characteristics and occupation of the Channel functions. Make sure that you are familiar with the setting and its features
After starting the motores, all motors must run and rotate evenly. Please fly carefully in small altitude until you know that everything is working fine.
Perform a pre-flight check by (off checklist, see below)
Start manually - switch off altitude control and GPS

During the flight

To do not take risks! Your own safety and that of your environment depend on the good behavior of the pilot.
Always keep a distance from people, animals and objects. Improper operation can cause serious injury and property damage!
Never fly towards viewers and avoid overflights of spectators
Keep in mind that viewers could get close to the MikroKopter, without being aware of potential dangers
Always turn off the MikroKopter first and disconnect the flight battery before turning off the transmitter
Only fly in sight. In the case of a manual control, you must be able to see the position and attitude
Never rely 100% on functions such as GPS, compass, or altitude control. You must always be able to take manual control of the MikroKopter
Reduce the gas or switch off the motores in case of a crash or failure
Do not fly in blocked air space, such as in the vicinity of airports, etc.
Pay attention to undervoltege warning - a flight to empty battery can cause damage to the Lipos and crash
If a defect or malfunction has occurred, it must be corrected before the next start
In case of use of GPS, the position of the MikroKopter can change suddenly some meters.

After the flight

disconnect the battery
Check for damage
Make sure that the propellers are not damaged
See the Handling and safety precautions of Lipos
After a crash the sensors and electronics might be damaged. Before the next start everything must be checked

Checklist (pre-flight check)

Weather conditions suitable
Frame and and all screws are tight
Propeller without damaging
Battery fully charged and securely mounted
Transmitter battery charged and the antennas are free
Channel of the transmitter is not busy. If 35/40/70MHz or other MHz-RC-controls are in operation simultaneously, the used channels must be checked with the other pilotes. At 2.4 GHz systems this is not necessary.
make a check of RC(TX/RX) operation range (on the ground!) from time to time (and before 1st flight)
There is nothing in the danger zone of the propeller
Enough space for launch and flight
The GPS module (if any) has GPS fix. If CH or PH is active: It will beep every second, not as long as enough satellites are received. Also consider: When you switch the GPS mode, it must shortly beep.
For manual start GPS and altitude controls are turned off
Sensors calibrated and the right setting is loaded
Should your location have changed significantly, re-calibrate the compass
The trim of the remote control is in neutral position
