Details

Built for 75mm indoor whoops, the V2 frame uses a reinforced rib layout to handle everyday bumps and crashes.

Use the size drawing to confirm wheelbase, duct diameter, and key clearances before choosing motors and props.

A 25.5×25.5mm FC mount and 14mm camera support make it easy to plan a compact 1S indoor build with the included hardware.
