Please try always to fly safe.
Here are my personal safety recommendations, especially for experimental drones of which you are not sure on how they can behave:
- make sure to always keep an HUGE distance between you and the drone
- always place yourself on the back of the drone before starting flying
- always have the direct sight to the drone and make sure that its orientation is clear for you (use different colors or LEDs)
- fly in private areas where no public can access
- make sure that nobody can come near the drone while you are flying
- make sure that you cannot destroy anything that you have around you with the drone
- check the wind and the weather before flying, if outdoor
- never go too high (no more than 1/2 meters in these cases)
- do not fly on top of someone (neither yourself)
- first try to fly few cm above the ground to see if everything is correct
- try to avoid using carbon fiber props (they are really like rotating knifes) but use plastic props
- try to use smaller drones with smaller props for really experimental tests
- triple check all the screws and that the frame is not cracked somewhere
- triple check all the DIY electronics, if it fails in-flight can be extremely dangerous
- make sure that the batteries are full charged (both transmitter and the LiPos)
