Product overview
The GEPRC GEP-DX4 Dolphin Frame provides the airframe for a UAV build using 4″ propellers and a 153mm wheelbase. Its physical structure specifies 4mm arms, a 2mm splint and a 2mm bottom plate, with motor mounting holes spaced at 9mm × 9mm. These dimensions define the main mechanical interfaces for component selection. The frame specification gives a weight of 39g; a separate additional-information weight is 200 g, without an explanation of the difference.
The product is a frame rather than a complete flight platform. Its recommended build configuration combines a GEP-20A-F4 AIO flight controller system, 1507 motors, a 20A-30A ESC and a 4S 600mAh ~ 4S 850mAh battery. These components are identified as recommendations, with no supplied electronics or detailed kit contents specified.
