interest Power Requirements 09 power will produce flight characteristics midway tween glider fairly docile powered trainer 15 power will produce fairly fast highly maneuverable craft capable very tight quick turns loops rolls stable inverted flight Dead-stick landings piece cake due excellent glide ratio Control Functions Only two servos required provide full flight control sliding servo tray shown plans de livers flawless elevon operation Elevons control surface function incor porates ailerons elevators single control-surface function ailerons accomplished connecting elevon pushrods single servo installed same ailerons sliding aileron servo tray produce up down elevator function arrange ment provides simultaneous roll pitch control just same would have conventional separate elevators ailerons Construction Methodology Simitar XV construction very quick simple use foam core wing sheeted 1/16 balsa gives tremendous strength combined ease repair field fuselage built flat

produce smooth flight Flight characteristics inherently stable stall undesirable yaw tendency Due configuration some initial fuss orientation wondering way its going generally overcome after first couple flights merely takes bit getting used Loops both inside outside rolls snaps verted flight almost other maneuver including fairly good 4-point roll Simitars bag tricks important rules remember
