DARWIN HULK II Waterproof FPV Drone Frame Kit (IP67) True-X 227mm, 5.5mm Arms, CNC Side Plates

Overview

DARWIN HULK II is a waterproof FPV drone frame designed by DARWINFPV for harsh outdoor environments. The HULK series is built with IP67 protection against water and dust, helping reduce build complexity when developing a waterproof FPV drone.

Compared with the first-generation frame, HULK II adds upgraded dual upper and lower camera mounts that can carry DJI O3 and a GoPro at the same time, enabling more flexible shooting setups (including underwater use). The frame uses thicker 5.5mm arms and a True-X, two-in-one arm structure to reduce empty space and minimize resonance.

Key Features

• IP67 water and dust protection (HULK series)
• True-X frame type with 2-in-1 arm structure to minimize resonance
• T700 carbon fiber plates
• High-strength CNC aluminum alloy side plates (5mm)
• 5.5mm arm plate thickness for higher strength
• 316 grade stainless steel screws and nuts; stated to retain appearance after 72 hours immersion in sea water
• Dual camera mount positions (upper and lower) for simultaneous DJI O3 + GoPro installation
• Integrated fixed XT60 connector mount for easier battery connection
• Bottom-arm screw washers to distribute stress and reduce carbon plate deformation risk
• Float structure with added penetrating reinforcing ribs
• Up to 52 programmable RGB LEDs embedded within the side panel
