originally appeared Thermal Tales newsletter Diablo Valley Soaring Society Greg Vasgerdsian editor Bob West Coasts consistently successful pilots Thanks guys Adding weight sailplane will give great advantage during certain weather conditions Most experienced pilots recognize fact still hesitate add ballast face 20-mph winds must little voice subconscious saying heavy planes sink.light planes float Theres some truth reality anything floating 20-mph wind going landing next county ballast works help Increasing weight sailplane causes fly faster Its like rolling volleyball bowling ball down hill heavier bowling ball will gain speed win race ballasted sailplane will make its downhill glide faster could dry unballasted theory added weight should affect glide slope within reasonable range means will cover same amount ground faster light right crowd say Ah ha Covering same ground faster means youll ground sooner No can argue fact least calm day light lift mild sink Throw some strong sink equation slow ship could ground before escapes big patch down air As wind comes up advantages adding ballast really become apparent have penetrating power search upwind lift important after youve found thermal have drifted downwind youll have extra speed potential needed penetrate wind back field Knowing much ballast add put big problem Prior experience best way decide youre out sport flying wind starts blow dont pack up Ballast up experiment dont have personal experience draw can always ask flying buddy what did flight says added pound beware could exaggerating trying confuse What kind buddy this/RB need know wing loading ounces per square foot wing area tells terms have useful information Ask him too much enough course put buddys comments use preflight decision making youll need know own planes dry wing loading have chart handy will tell wing loading various amounts ballast plane will react differently ballast pilot flies varying degrees aggressiveness must also considered

plans put nose down really search need carry enough ballast get moving significantly faster wind speed plane handles weight differently need experiment find out yours will react plane light side experiment adding small amount lead very light wind conditions will make fly little faster will also help keep track get hit wind gusts landing approach course stronger wind faster airspeed need faster need fly ballast add Eventually will reach point planes glide ratio deteriorates noticeably Ballasting beyond point usually fruitless Draggy floater types will reach point lower wing loading slicker highperformance ships Once determine point youll know complete window loadings available know keep beating around bush want real numbers want know exactly what wing loadings will work Im probably going regret sake beginners probably still completely dark opinions some broad rules thumb Gentle Lady-type two-meter will probably benefit ballasting up about 9 ozIsq ft wing loading stronger two-meter faster airfoil like Sagitta 600 can go up about 12 os/sq ft big old Paragon its draggy high-lift airfoil should probably go beyond 11 os/sq ft polyhedral Sensor 117 maybe 13 os/sq ft newer breed ships such Falcon 880 Legend may benefit up 15 ozIsq ft loading Increase wing loading increments about ounce per square foot anything less will hard notice Unless build really heavy should probably consider adding ballast winds above 8 mph hope Ive convinced try little weight Now need figure out put Ballast usually form lead needs secured directly over centerof-gravity Anywhere else means changing trim CG plane well adding weight enough ingenious ways mounting ballast fill another article Just make sure cant shift fall out during launching hard landings Note safety AMA rules state ballast must carried inside plane Thanks sharing knowledge Bob think beauties soaring hobby notion always something leam.always something new try. always plenty scope improve ones flying keep trying improve glider flying never gets boring As making ballast pieces please remember decide melt lead like readily available automobile wheel weights cast special shapes molten lead fumes toxic
