Shendrones Hydrophobe for DJI FPV
The Hydrophobe is a 255mm water resistant 5" cine quad with a 2mm aluminum mid plate that doubles as a heat sink for your esc and vtx. It has a 3mm bottom carbon plate, 6mm arms, and 1.5 mm top plate. A TPU skirt keeps rain, snow, and dirt out, augment it with sealant to make it as waterproof as possible.
Use nonconductive thermal paste to transfer heat, but don't let bare boards directly contact the aluminum.
The arms have mounting points for floats. I epoxied standoffs in pool noodles for a quick and simple float.
Hero 5-7 or 8 cam mounts are available. The DJI skirt has antenna holders, the Analog/Vista skirt has a 17mm antenna tube. An Immortal T holder is also available to screw on to the top plate.
