Price 5OO Heres what Northeast Sailplane Products new 1991 catalog looks like lists Incred ible amount goodies RC Sailplaner time Full-size sailplane pilot modeler Bob Wakerly taught secret years ago said flaps out keep nose pointed ground Its simple rule Follow will find key consistent landings Thats really need know Ill elaborate just little further have remember flaps deployed wing has camber its stalling speed reduced can now fly slower possible flaps neutral can get yourself no-win situation may need retract flaps avoid landing short ow plane will stall out instantly avoid problem keep nose down dont go slower plane could fly flaps neutral Its tempting go slower try resist getting super slow until just prior touching down Dont underestimate importance keeping speed just right throughout whole approach pattern Flying speed bit important controlled landing altitude styles approach patterns pilots Ill describe use give some ideas Its tailored flying style capabilities equipment Flite Lite Composites Falcon 800 standard class Airtronics Vision 8SP radio main thing fly same approach works youevery time like see Falcon come over shoulder begin downwind leg 20 seconds go point Im about 60 feet high have half flaps deployed about 45 degrees around 13 seconds go depending wind conditions begin 180 line up final point find very helpful get fuselage precisely aimed

new kits use balsa-and-foam construction promise details near future using aileron coupled rudder keep wings level done quickly gently heading problems avoided before occur Falcon comes rails final work flaps between half full adjust altitude speed approach timing Visions automatic flap-elevator compensation set keep nose pointed down elevator stick remains neutral way too high add down elevator full flaps dive away excess altitude resume normal approach angle try enough distance spot excess speed gained will have time bleed back off final approach looking way too low retract flaps way leave out little help avoid possibility stalling about 25 feet spot three feet high start level off flare out allow speed drop almost stall havent already Ill deploy full flaps now just right instant foot less off ground jab down stick simultaneous flap retraction puts nose right spot Although little off subject Id like mention crow function both ailerons deflected up may want use crow independent flaps maximum versatility coupled flaps simplicity crow deflection have higher sink rate Some people like much 455 have Falcon set couple 1/4 inch crow 900 flap small amount has subtle effect can still float flaps Its just enough keep floating excessivelyand right past spot full flaps deployed Vision radio reverse aileron differential switched automatically still allows down-going aileron deflect below wing despite fact neutral point 14 inch above wing crow helps maintain maximum roll rate critical landing approach last note control setup Make sure have lots down elevator throw Youll find typical amount needed normal flying will allow fuselage rotate downward very quickly 900 flap application have elevator end point adjustments Vision set give twice much down up Just add bit what Bob said about crow Ive always thought being combination flaps down ailerons up glider has ailerons flaps its effective couple together optimum glide path control Assuming course have Vision X-347
