I present, the Nifty 50. This may just be the smallest betaflight running fpv quadcopter out there. It measures just 50mm motor to motor diagonally! This frame was designed to clip together, eliminating the need for hardware, and keeps the weight to an absolute minimum. The frame weighs in under 2g. It was designed with a specific Flight Controller in mind (linked below) but will accept a variety of receivers, fpv systems, and motors. Camera mount angle is 30 degrees.

Note: This is an advance build, not recommended for beginners.

Components:

• Eachine Tiny F3 Flight Controller- https://www.banggood.com/Eachine-Tiny-32bits-F3-Brushed-Flight-Control-Board-Based-On-SP-RACING-F3-EVO-For-Micro-FPV-Frame-p-1087648.html
• EF-02 AIO 25mw Camera, Split. (Will accept other AIO cams such as the TX01-04, CM275T, and many others. Some may fit without being separated but it is recommended)- https://www.banggood.com/Eachine-E010C-E010S-Spare-Part-p-1119217.html?rmmds=search

Note: Pictures are from the first version of the frame and was mocked up with multiple components. Overall not much was changed. The front clips were beefed up to be stronger and the height of the top arms was increased a bit. Projected weight of the frame is 1.9g.
