The QAV400 Airframe

qav400-in-flight The QAV400 is an FPV quadcopter frame based on the inovations that we introduced in the QAV500, but in a much smaller form factor. The QAV400 is 100mm smaller in size (motor axle to motor axle diagonally). The frame weighs 375g (without landing gear). Just like the QAV500, the QAV400 is extremely stiff due to the materials used and construction methods applied. This model uses black anodized milled aluminum arms. This airframe exhibits extreme acrobatics and maneuverability while still maintaining crystal clear 1080p video making the frame a great pairing with the GoPro 3 Black Edition.
