The Blade® Theory™ XL Frame Kit is a new and vastly improved FPV frame kit. This "stretched X" design delivers flight characteristics that are perfect for FPV racing, increased stability while pitching and flying fast forward. The durable 4mm carbon fiber main plate offers the lightweight durability that every FPV Racer desires. Weighting in at under 80 grams, this frame sheds all necessary weight without sacrificing durability and space. The bottom plate features designated cutouts to run the battery strap below the quad, reinforced arm tips to protect the motors in a crash, and industry standard 30.5mm standoff cutouts to mount nearly any power distribution board or flight controller. The 30mm standoffs that separate the bottom plate from the top also offer plenty of room to mount electronics such as receivers, video transmitters, or lap timing systems in addition to the flight controller and power distribution board. Additionally, the top plate has patterned cutouts that allow for easy access to nearly all video transmitters. Two vertical pieces of carbon fiber create a versatile and durable camera mount that offers 0 to 90 degrees of tilt, perfect for HS1177 style cameras. Motor mounting holes can host a variety of dimensions, from 16mm to 19mm motors. The Theory™ XL is the perfect FPV racing frame for every pilot, from the intermediate backyard flyer, to the national competitors.
