Last February, the blog reported on the low-cost Flying Flea formula, four-motored ultralight that Nedo Lavorini built and flew.  Unknown to your editor at that time, YouTube has videos of the construction of what turns out to be at least three fuselages.  That answers the question of why the aircraft flew with at least two landing gear configurations. Parental and Spousal Warning: You may want to view the video privately before allowing your children (or wife) to see the following.  There is a bit of eye candy in Nedo’s workshop, and even the cameraman seems to be distracted momentarily. The flying video gives a new meaning to the term “tree hugger.”  The Pulce Elletricca seems not to have a great rate of climb with its four 2 kilowatt Chinese model airplane motors doing their best to lift the 330-pound all-up-weight flea.  It’s a heroic effort for the pilot, and the under $5,500 total cost for the nicely crafted machine is certainly …

The Pulce’s light weight and tandem wings of 5.3 meter (17.93 feet) span with a combined wing area of 13 square meters (just shy of 140 square feet), give a wing loading of a mere 11.54 kilograms per square meter, or 2.37 pounds per square foot – just right for the …
