The GEPRC team is enhancing and optimizing the overall performance of the MARK5, and will also release a new MARK5 O3 version equipped with the DJI O3 air unit. This version comes in two variations: MK5D and MK5X. The camera's aluminum alloy side plate has been newly upgraded to 7075-T6 aluminum, making it incredibly strong and durable. It is compatible with DJI's new O3 air unit camera, boasting a wide 155° field of view (FOV) and the ability to record in 4K at 60FPS. The Deadcat frame structure provides a wide and unobstructed viewing angle during flight, perfect for onboard video recording and direct output. We have also designed TPU soft printing parts specifically for the O3 VTX module, with an air inlet cooling.
