Radio Control Sport & Aerobatics Ron Van Putte RESPONSES As expected first let ters about effects wind aircraft began arrive less week after August issue mailed out What didnt expect moderate tone letters may change letters come far letters disagreed claim airplane unaware steady wind have cor dial restrained Some letters didnt really disagree asked questions about apparent contradictions due observa tions made strong winds good example apparent contra diction made Jim Thomerson Collinsville IL letter also con tained key apparent contradic tion regards comment wind August 84 MA sounds very sensible have student pilot other day talking him whilst getting little Cessna ready takeoff South America put very simply Wind doesnt affect rate climb just quick get going fly Control Line Precision Aero batics middle Advanced level can assure CL airplanes tend climb going wind dive go ing downwind also slow down go ing wind speed up going downwind somewhat would ex pect trying fly Inverted Flight maneuver fly six laps inverted trying stay 49 feet off ground whole way judges just outside circle upwind side see airplane trying climb coming toward dive going away com pounds pilots problem think climb dive partly because airplane flying free path Thats answerR VP partly because aircraft does have time adjust its speed horizontal add subtract everchanging wind speed vector case can appreciate concentration has put keep changing airplane trim keep same altitude six laps wind blowing point envy have RC fliers can fly quite well winds ground CL Aerobatic airplanes Isnt amazing different point view can often prove point years Ive saying reason wind causes problems because pilot forcing airplane fly pattern relative point reference What better example Control Line airplane motion CL airplane constrained lines rather flying free Its constraint causes pro blems flying CL airplanes wind similar effects observable RC airplanes constrained pilots inputs also received very nice letter Bill Winter MA s Just Fun columnist way Bills letters just like columns folksy ram bling downright entertaining Bill asked some interesting questions based experiences suggested should expand confusing ap plication laws conservation energy momentum problem airplanefloatingin moving air mass Ill future column also posed two interesting situations experience first noticed Wakefields before RC used very hi2h-Ditch prop oerhaos quite enough rubber ship raced downwind turning early adjustments ship rpm slowed down tremendously prop flailed What did understand floating air mass made no difference rpm went down drastically going downwind going wind speeded up almost implied air somehow pushing plane plane way going downwind Perhaps unrelated case situation old Rubber Duration models moderate dihedral flew fine reasonable conditions would appear have low-side wing panel entrapped airflow turn made wind wing would held down until spiral dive met earth Adding bit dihedral stopped As can imagine am loss ex plain what Bill observed would naive say didnt really see what 56 Model Aviation Ruth Carison treasurer Chandler Sport Fliers Arizona seems quite happy second

What happened Well stiff wind reduced bit air speed airplane went below its stall speed stalled object good idea have bit extra airspeed landing gusty winds engine should reduced idle just before
