Details

Built for harsh environments, HULK combines an IP67 sealed design with floating foam to help keep the antenna above water.

Choose the DJI O3 version for a CNC aluminum waterproof case designed for better heat dissipation.


A GoPro-ready mount, stabilized XT60 lead, and soft side-plate connector help reduce vibration for smoother cinematic footage.

Clear connector labels make wiring the camera/VTX, receiver, and power leads straightforward during setup.


The squashed-X frame uses multi-structure shock absorption to improve stability and reduce shake in flight.
