grown out trials hang gliding early 1970s Whatever cause am dedicated soaring would also have agree older friend Bob Moore also life-long soaring enthusiast said Gliding purest form flight Heres Ritz 2-30-10 airfoil section used two models mentioned text de signation teiis 10-in section has camber 2 maximum thickness io cated 30 percent chord that section 10 percent thick should explain first exposure RC soaring back 1976 time entered hobby recovering hang gliding accident order have relaxing fun safe form entertainment turns out has RC soaring has become integral part life hobby has provided pleasure building flying designing writing about also write Slope Soaring column RC Soaring Digest probably advantageous parts hobby socializing people build fly silent RC creations have unknowingly offered tremendous amount good honest creative friendship simple fact has certainly provided hope incentive participate incredible avenue model aviation though admire soaring varieties passion hobby lies slope soaring might guess infatuation came about after first trip slopea trip witnessed what pilot could encourage model flies lift generated slope environment beginning building flying planning slope flying outings beginning still vivid mind assuredly still motivates Now let quickly explain way see slope soaring fraternity what hopes promise RC Slope Soaring activist As

ever seen thermal field models cases employ state art both technology design models have evolved withstand winds 60 mph greater aircraft can well exceed 140 mph diving through tremendous lift can generate slope environment Slope Soaring can produce desire its participants build fly some beautiful soaring machines scale creations cannot fly other setting slope So what see Slope Soaring also healthy soaring movement general healthy because slope format can generate stimulate designs design ideas can readily carry over other areas RC Soaring concept design idea comes about part soaring just may idea assists US F3B soon-to-be F3J pilots winning World Championships just may F3F some variant thereof will come healthy positive Slopers community US So whats new Lets hear guys gals out Id

grown out trials hang gliding early 1970s Whatever cause am dedicated soaring would also have agree older friend Bob Moore also life-long soaring enthusiast said Gliding purest form flight Heres Ritz 2-30-10 airfoil section used two models mentioned text de signation teiis 10-in section has camber 2 maximum thickness io cated 30 percent chord that section 10 percent thick should explain first exposure RC soaring back 1976 time entered hobby recovering hang gliding accident order have relaxing fun safe form entertainment turns out has RC soaring has become integral part life hobby has provided pleasure building flying designing writing about also write Slope Soaring column RC Soaring Digest probably advantageous parts hobby socializing people build fly silent RC creations have unknowingly offered tremendous amount good honest creative friendship simple fact has certainly provided hope incentive participate incredible avenue model aviation though admire soaring varieties passion hobby lies slope soaring might guess infatuation came about after first trip slopea trip witnessed what pilot could encourage model flies lift generated slope environment beginning building

non-competitive has maintained rather laid back benign image true part Slope Soaring does have another facet has aspect both healthy model aviation fun participantsthe flying soaring aircraft rarely ever seen thermal field models cases employ state art both technology design models have evolved withstand winds 60 mph greater aircraft can well exceed 140 mph diving through tremendous lift can generate slope environment Slope Soaring can produce desire its participants build fly some beautiful soaring machines scale creations cannot fly other setting slope So what see Slope Soaring also healthy soaring movement general healthy because slope format can generate stimulate designs design ideas can readily carry over other areas RC Soaring concept design idea comes about part soaring just may idea assists US F3B soon-to-be F3J pilots winning World Championships just may F3F some variant thereof will come healthy positive Slopers community US So whats new Lets hear guys gals out Id

tells airfoil 2% overall chord camber Thus 10-inch section would have camber 2 inches Also section has its maximum thickness located 30% chord finally section 10% thick Unfortunately LID polars unavailable time because its record performance can tell section very good choice scale ship section provides very good handling quite wide speed range also believe has very reasonable drag bucket because climbs well lift indicates lift well encounters section will allow aerobatics too should choose turn model upside down last least section thick enough can build wing sufficiently strong
