A ducted fan approach may work. Ducted fan hovercraft have one or two big fan blades on the back that push the craft forward, but a duct takes some of the air and uses it to fill the skirt. This is probably the "lightest" design approach. Direction (...) (21 years ago, 27-Nov-02, to lugnet.robotics)

(...) 100% LEGO yes, but I'm planning on using LEGO (maybe ZNAP at first, then a mix of Technic) as the "wire-frame" and then use plastic (...) (21 years ago, 27-Nov-02, to lugnet.robotics)
