The flight is extremely quiet due to the fact that the drone glides for most of the flight. On the other hand, the electric motor used to drive the drone, powered by lithium-polymer batteries, is characterized by quiet operation. Just before landing, the under-fuselage section with the observation head is jettisoned a dozen or so meters above ...
Eristalis arbustorum, the European drone fly, is an abundant Northern Hemisphere species of syrphid fly, originally officially described by Linnaeus in 1758 as Musca arbustorum.

Drone flies and their relatives are fairly common generalist pollinators , [ 2 ] the larvae of which are aquatic, and breathe through a long, snorkel -like appendage, hence the common name rat-tailed maggots .
Eristalinus taeniops can reach a length of 11–14 millimetres (0.43–0.55 in). [5] These hoverflies exhibit a bee-like yellow and black coloration (Batesian mimicry) and are often mistaken for wasps or bees.
Eristalis tenax, the common drone fly, is a common, migratory, cosmopolitan species of hover fly. [2] It is the most widely distributed syrphid species in the world, and is known from all regions except the Antarctic. It has been introduced into North America and is widely established.

The Netra is a lightweight UAV, manufactured by carbon fiber composites, that uses quadcopters to provide lift and control giving a VTOL capability. It has no moving parts other than the rotors, motors and transmissions, and hence it requires very low maintenance.
Eristalis flavipes, the orange-legged drone fly, is a species of hoverfly native to North America. [1] It flies from early April to mid-October, and occurs in a wide variety of habitats, particularly wetlands. Hoverflies get their names from the ability to remain nearly motionless while in flight.
