Summary:

The unmanned aircraft fell to the ground from a height of 20 m due to a loss of electrical power. This was caused by separation of electrical connections due to thermal damage of the UA and battery connectors. Damage was also found to the batteries fitted during the three previous flights.

The manufacturer has updated the Sky Mantis Operating Manual to highlight the need to check the aircraft and battery connectors during pre-flight checks.
