Scubi FPV
A frame good for 2.5" (with 30.5x30.5) or 3" (with 20x20).
Tough, yet light, this little frame has shown to be a quick little devil! It will need a 3D printed pod to go on top.
Easy to put together (1 piece!) and a blast to fly.
30.5x30.5 FC recomendation: RacerStar AIO 4in1 (One board to do ESC and FC. Even has an OSD!)
20x20 FC recommendation: HGLRC 20x20 stack with OSD (higher stack, but I've had great results with these boards)
