Quadrotor Drones 

The Lumenier QAV250 Mini FPV Quadcopter airframe. With small yet fully functional FPV quadcopters having gained a lot of popularity recently, we decided to design a small FPV airframe that deserves the QAV label. The QAV250 is a symmetric 250mm size airframe that accommodates 5" props. The 250mm is measured motor shaft to motor shaft diagonally.
