Ukrainian developers said they lubricate drones with lard to protect them from the cherry. The Ash Point company reported that before launching UAVs in the cold, the operators coat individual parts with lard. It should be noted that the fat film helps protect surfaces from moisture and frost. However, lard does not replace full thermal insulation: its protective properties are limited, and when heated, it can melt.
