4 inch o4 pro fpv frame (238 gram)

It was designed a long time ago. Flight controller mount pattern is 25.5x25.5 mm. Step file is provided in order to make a .dxf for frame manufacturing and printing gps, antennas and camera mounts. 6-8 mins of active flying, 15+ mins are pretty easy to achieve when cruising. Weight without battery is 168 grams and weight with 850mah 4s is 238 grams. The middle plate had holes for press-nuts, but I removed them from the model. If you want to use press-nuts, enlarge these four holes yourself to the desired size. Tested with: DJI O4 pro RCINPOWER SmooX 1404 plus 2750KV RUSHFPV Micro M10 gps module (12x15 mm) Jhemcu GHF722-AIO GNB LIhV 850 mAh 4s (long type).
