Formula: {Weight_XCopter = variable}

XCopter weights vary considerable.

Firescout
~ a folded length of 23ft
~ three bladed rotor has a diameter of 27ft 6in
~ vehicle stands 9ft 5in high
~ gross weight is 2,550lbs = 1159 kg
~ has an endurance greater than six hours
~ providing a loiter time of more than four hours at a combat radius of 110 nautical miles
~ Schweitzer has developed a four-bladed rotor hub, which will extend the UAV's range, payload and endurance
~ The Schweitzer 330 uses a Rolls-Royce Allison C250 engine generating 480shp
~ the engine provides a maximum speed of more than 125 knots
~ and a flight ceiling of 20,000ft

Hummingbird A160
~ can reach high altitudes, hover for long periods of time, go greatr distances and operate quietly
~ it features an optimum speed rotor technology that enables the Hummingbird to adjust the RPM (Revolutions Per Minute) of the rotor blades at different altitudes and cruise speeds
~ is designed to fly 2,500 nautical miles
~ endurance is in excess of 24 hours
~ payload more than 300 pounds = 136 kg
~ is 35 feet long with a 36-foot rotor diameter
~ will fly at an estimated top speed of 140 knots = 259 km/h
~ at ceilings up to 30,000 feet, which is about 10,000 feet higher than conventional helicopters can fly today
