Like any other appliance, an unmanned aircraft needs regular maintenance. Even the smallest damage to, for example, a propeller can cause the unmanned aircraft to become unbalanced and uncontrollable. The manufacturer will also describe the maintenance requirements in the manual. Make sure that maintenance is properly mentioned in the logbook of the unmanned aircraft.
