The Lumenier QAV-XS Stretch FPV Racing Quadcopter is a Stretch-X, lightweight, super stiff, finely tuned airframe designed for high-performance FPV Drone Racing. This racing airframe is stripped down to the bare essentials without sacrificing strength and durability. The Stretch-X has outstanding handling characteristics on pitch for a locked in, high speed forward flight, and quick snap rolls. This version features an ultra-durable 4mm carbon fiber main unibody plate.
The QAV-XS, like the QAV-X CHARPU, features a unique FPV camera and HD mounting system. The FPV camera is recessed partially below top plate and protected by the top crossbar, guarding your electronics. At the same time, the camera side walls act as an angled wedge to set your HD camera on for recording, such as a GoPro, at a 35-degree angle. No need to 3D print custom mounts to angle up your camera anymore, just add some of the included neoprene foam, securely strap down your camera and fly!
The main "unibody" 4mm plate is CNC milled out of a solid sheet of premium Lumenier carbon fiber. The outer weave of the carbon fiber runs in line down each arm of the QAV-XS (0/90 weave), maximizing the strength of the carbon and arms. The center layers are offset at 45 degrees providing even and balanced strength throughout the entire plate. The main plate and top plate have a chamfered edge on top and bottom giving it a nice finished look and removes any sharp edges. Each piece of carbon is cleaned and sprayed with a clear coat for a premium finish. There is no sanding required and no messy carbon dust.
The top plate includes an antenna SMA mounting hole, and cable tie holes allowing you to lock down your antenna in place. The top plate also has a cutout allowing access to your VTX button and LED displays for easy channel adjustment. The balancing bumps on the sides of the top plate make it easy to measure the center of gravity on your frame in the field to get a perfect balance.
Each kit includes a carbon fiber battery protector plate. The airframe is designed to strap a LiPo battery to the bottom, leaving the battery exposed during a hard landing or crash. Use this included plate to wrap underneath the battery, sandwiching the pack between the main plate and protector plate. Additionally, you can use the included Neoprene foam to create a landing pad on the bottom of the battery protector plate. This will help keep the airframe upright during take off and landings.
The airframe comes with high quality aluminum hardware. All screws are premium, black oxide steel. The spacers have a textured grip surface treatment, which facilitates holding of the spacers during assembly and servicing of the airframe. The spacers are also 28mm tall vs the standard 35mm. This gives the airframe a sleek, low profile look.
Included with the QAV-XS Stretch kit is the popular Lumenier 4Power power distribution board which can be fitted with an optional Pololu voltage drop-down circuit (to 12v or 5v), a XT60 pig-tail. Like the QAV210/180, the QAV-XS kit enables mounting of small FPV cameras such as the Lumenier CM-650 in a fully encased assembly which protects the FPV camera during crashes and enables pointing the FPV camera at a wide variety of viewing angles.
