The All About Trikes DVD is the only one of its kind. It was created to promote our entire sector of aviation with no bias toward any particular brand, instructor or supplier. The end result is a stunning, high-definition, fast-paced introduction to Trikes (Weight Shift Control Aircraft) and the most common questions people have. Your interest in our sport is respected & appreciated very much BY OUR ENTIRE INDUSTRY and your purchase of the DVD assists with the little things – like calling & emailing people back with answers & free education. Extra tools & databases are included on the DVD as well.
