running long kept good head speed wind kept blowing Haboob came flight designed specifically wind flying utilizes lightest efficient struc ture possible geodesics first design built-up wing flaps elevator covered Japanese tissue too much trouble limited benefit current design uses stock balsa sizes relatively easy build Two power options available model engine can used getting model up wind-flying speed model will wind-fly efficient ly drag propeller engine 15 engine will provide spectacular per formance ordinary kind isnt purpose article can wind provide power Control Line model does kite fly Perhaps answer first question similar second onebut effects whipping thrown theory wont pursued further ever can tell what to make work After building flying Ha boob will able tell works Follow steps learning wind-fly First determine line length initial flight testing being height can reach holding lines midpoint outboard wing tip ground length will enable take off easily assistance Fly few times short lines will turning fast getting dizzy easily will become familiar Haboob handles will find responsive light controls will see can de termine desired airspeed leading whipping model Get used flying low smoothly control inputs add drag slow down model new non-conductive control lines Sullivan Products ideal wind flying safer use steel control lines Next go moderate control line lengths say 25 30 ft will need person launch model lines will long enough learn use wind perform some basic stunts Begin day light breeze Have helper run fast can throw model hard can still being able get model airborne smoothly very im portant have airplane released wind downwind controls neutral first step pilot get plane down low Fly very smoothly start whipping hard can Once have passed through upwind side circle safely have made Build speed whipping hard through down wind side again After few laps like December 1985 81 Above I ne Y2A-engined version intended used stooge self launching
