Alex Weiss has been aeromodelling for half a century and has built more than fifty radio-controlled models of which 28 were original designs and 14 were published in RCM&E or Radio Modeller magazines. As well as monoplanes and a biplane, the list includes an autogyro, canards and deltas. He has also written magazine articles on subjects as diverse as four stroke engines and flutter. The author first went solo in a Chipmunk with his University Air Squadron at Tangmere and his early adult life was spent as an RAF pilot, flying Jet Provosts, Vampires and Hunters, including three years as a qualified flying instructor. Much of his professional experience has been dedicated to the complex subject of teaching people to fly radio controlled models.
