This model kit is in 1/700 scale. The single sprue is connected by wires under the vehicles. It includes: 4x Bell Boeing Quad Tiltrotor Aircraft. The Aircraft are armed with the same weapons you would find on a KC-130 Harvest Hawk, also available from this shop.
According to Wikipedia: "The Bell Boeing Quad TiltRotor (QTR) is a proposed four-rotor derivative of the V-22 Osprey tiltrotor developed jointly by Bell Helicopter and Boeing. The concept is a contender in the U.S. Army's Joint Heavy Lift program. It would have a cargo capacity roughly equivalent to the C-130 Hercules, cruise at 250 knots, and land at unimproved sites vertically like a helicopter."
