Editors note As article being prepared learned passing Bill Winter December11 1998 sympathies family friends associates modeling reliminary specifications discussed new 40-powered model outstanding low-speed characteristics flight cnaracteristics similar designers classic Rookie early 1960s seemed logical couple design parameters Rookie long-nosed styling crop duster thus Duster model does push envelope brute power speed Duster combines more-realistic side model performance above-average aerobatic capability flight-test series showed Duster met exceeded design expectations solid performance moderate-to-low velocity areas compromising top end As RC pilots have benefit flying horizon over dash varying air pressure over controls provide feedback directly through sticks some modelsand Duster oneprovide ample visual clues give us feedback allows us change being person ground manipulating uncomfortably small sticks black box becoming model recent fun-fly event object land playing card
