Safety

 

A multirotor device, similarly to a helicopter or a fixed wing plane is not a toy. Just like a car, we can think of it as a weapon when armed, so we need to turn to it with a responsible attitude.

The propellers, no matter what material made of can cause huge damage in a fracture of a second. be aware of the fact that we can easily cause injury either to ourselves or to anybody else, so we have to take all the precautions to avoid such situations.

To avoid such accidents, it is highly recommended to keep the following at all times:

  • before turning any RF emitting device on, be sure we are not going to make harm to any device, already working on that given frequency
  • always power on the RC transmitter first, and the multicopter only afterwards
  • always power on the video receiver first and check if anybody is using the frequency we intend to use, power on the video transmitter just after this
  • before arming the FC (flight controller), make a few steps back, never stand/sit right beside the model
  • a systematic check of mechanical/eletrical components (cables, connectors, screws, …) prior to any flight is highly recommended
  • after doing any major firmware modification (upgrade), power/arm the multicopter for the first time with all propellers off
  • after we make changes to the RF systems (FW upgrade, component change,..) check the link stability with ground tests prior to flying
  • never leave a multicopter unattended, if it is powered/armed, as well as the transmitter if powered
  • never (EVER) fly above people or towards people
  • make sure that no live being (people, animals) is able to closing in at the takeoff/landing area, especially during takeoff/landing
  • when flying LOS (line of sight), never let the copter out of sight, even if there are GPS and other automated systems activated
  • never fly above roads with active traffic
  • generally, never fly above an urban area
  • do not fly in a closed (controlled) airspace or forbidden heights
  • it may be useful to think about the countermeasures to take in case of potential issues that we think that can occur, prior to they happen

 

Legal aspects

 

Even if there is no personal injury, we have to bear the responsibility for the damage caused in some cases.

 

These may be the following:

  • illegal frequency usage, or transmitting on an allowed frequency with not allowed power levels (HAM license existence)
  • accidentally powering the vTX on a frequency that is already used by someone else, causing to blind him and crash
  • damage caused by unattendance or technical problems
  • illegal usage of the airspace
  • illegal usage of the flying area

 

The worst issue ever would be to fly close to airports or in forbidden airspace. Doing so an accident can anytime happen, and in case of an impact with an airplane, the damage cause is unpredictable.When we fly on a field that is not specified for flying it is recommended to get a permission from the owner of the field (land).
