The AlfaRC Fi-115 is a compact 2.5" frame designed primarily for building a freestyle drone suitable for flying in the garden or park. The Fi-115 features a bottom plate made from 3mm thick carbon fiber. Combined with triangle-shaped arms, the frame is both stiff and durable. It has mounting holes with a 20x20mm pattern for standard stacks and 25.5x25.5mm for AIO boards. The top plate includes 20x20mm M2 mounting holes for easy installation of a video transmitter. The frame comes with a 3D-printed mount for a GPS module measuring 17x12.5x5mm and for an FPV antenna. It is designed for nano-size cameras as well as the DJI O4 camera, with the camera mounted using soft TPU inserts to help reduce vibrations.
