RC Skirtless Hovercraft - Stability Port Duct for 10" propellers, square base
thingiverse
Round to square base duct as seen in my 2023 design summary. Suits 10" propeller, 6mm base foam and ~70mm internal hull height.This diffuses the stability flow further than the round duct, hover height will likely reduce slightly, in exhange for less turbulence on water.Consider fitting vanes (moveable or not) in the square base for propulsion from the stability flow. I use 0.6mm walls on my build. 0.4mm was too fragile given the shape, 0.8mm is rigid but heavier.
