Flip down your visors and inflate your g-suits, jet jockeys....this 190MM F-16 "squinty scale" glider is sure to push your printer into the "danger zone". (sorry...I couldnt help it) An excellent flyer, this is one of my all time favorites for big air. If you like this glider, be sure to check out http://threedsy.com for printing tips on our blog, as well as more printable planes and an unbranded version of this one. You will need a launcher ( http://http://www.thingiverse.com/thing:95765 )and a pair of 8" x 1/8" rubber bands in tandem to get enough thrust to explore the flight envelope of this glider.Launcher and tools: For instructions look at my glider instruction thing:1465700.For tips on printing glider wings, drop by my blog at threedsy.com and if you like our models, keep us designing for you instead of flipping burgers by purchasing one of our premium designs from the site!
