3D-printable model file for an adapter for FPV drone flight controller and ESC boards. This 3D printable adapter plate allows you to mount a 25x25mm (actually 25.5x25.5mm hole spacing) All-In-One flight controller board onto a FPV quadcopter frame that is designed for 20x20mm or 30x30mm (actually 30.5x30.5mm). The version without the pegs works well to adapt from 20x20mm and 30x30mm easily mount.
