| | | (...) The experiments we've done with the helicopter suggest that you can generate some pretty impressive volumes of fairly slow moving air - but high speed/low volume is hard. The RDS insect wings that we used on our helicopter work really well, (...) (22 years ago, 26-Nov-02, to lugnet.robotics)

| | | | 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 (...) (22 years ago, 27-Nov-02, to lugnet.robotics)

| | | | | (...) Basic LCAC design. The air that drives the skirt is -not- derived from the direction fans but rather from the turbine input plenums (those babies will suck as much air in just a few 10's of sec. as goes through your entire house in year). If (...) (22 years ago, 27-Nov-02, to lugnet.robotics)

Take a sewing thread spool (the old wood kind work best) and (...) (22 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 (...) (22 years ago, 27-Nov-02, to lugnet.robotics)
