The DeepSpace Stellar 25 is a frame designed for building a compact 2.5″ cinewhoop, ideal for indoor flying or smooth outdoor flights. The frame supports both analog and digital video transmission, including DJI O4 Pro. The front section of the frame features an aluminum camera cage, with the camera mounted on rubber inserts to help absorb vibrations. Above the aluminum cage, there is a dedicated 16x12x4.6 mm space for installing a GPS module.

The center of the frame is designed for an AIO flight controller with a 25.5×25.5 mm mounting pattern, as well as a video transmitter. Mounting holes with both 20×20 mm and 25.5×25.5 mm spacing are available for easy VTX installation. At the rear, the frame is equipped with a firmly mounted XT30 connector and a USB-C port for convenient setup of the AIO board.
