MARK4 7 inch H-type carbon frame, 295 mm wheelbase and 5 mm arms. 20×20 / 30.5×30.5 stack, 19 mm camera. Unassembled 7 inch freestyle kit.
The MARK4 7 inch is an H-type 3K carbon frame for 7 inch freestyle and long-range FPV. Motor-to-motor wheelbase is 295 mm, so it swings 7 inch props. Arms are 5 mm carbon — the 295 mm figure is the wheelbase, not the arm thickness.
Overall footprint is about 193 × 223 mm. The stack bay takes 20×20 mm and 30.5×30.5 mm flight controllers (centre or rear). Camera cage is about 19 mm micro. Motor bells typically land on 16×16 mm and 19×19 mm patterns. Aluminium standoffs are about 25 mm, which leaves room for a 4-in-1 ESC and a VTX.
Top, bottom and side plates are 2.5 mm; bumper / protect plates are 2.0 mm. Typical kit weight is about 121 g. Kit ships unassembled. Pair with a 40–60 A stack on 4S–6S. This is not a 5 inch racing frame.
