3.5英寸FPV无人机3D数模图纸 STEP格式

This is the fit FPV drone I have built. Before that, I used to fly the DJI FPV and I really loved FPV. So I designed a drone that can hold its position and reach up to 20 minutes of flight time. I used the MTF-01 optical flow for it. Since this is the fit O3 air unit I bought, it comes with both a cooling fan and a le cover for protection.
