need know what speed rotate Too soon could stall too late waste towing distance height Next need know what speed climb what angle climb phase pilots get nervous about because have effect elevator reversal mean pulling stick back increases airspeed tow pushing forward decreasesjust opposite gliding flight RC pilots already know because ground-tow time first flight really exciting After years launching RC gliders now experiencing what like top side After glider achieves steep tow angle rope tension high begins sing wind An unsettling thing after glider becomes airborne pilot can no longer

launching RC gliders now experiencing what like top side After glider achieves steep tow angle rope tension high begins sing wind An unsettling thing after glider becomes airborne pilot can no longer

launching RC gliders now experiencing what like top side After glider achieves steep tow angle rope tension high begins sing wind An unsettling thing after glider becomes airborne pilot can no longer

need know what speed rotate Too soon could stall too late waste towing distance height Next need know what speed climb what angle climb phase pilots get nervous about because have effect elevator reversal mean pulling stick back increases airspeed tow pushing forward decreasesjust opposite gliding flight RC pilots already know because ground-tow time first flight really exciting After years launching RC gliders now experiencing what like top side After glider achieves steep tow angle rope tension high begins sing wind An unsettling thing after glider becomes airborne pilot can no longer see tow vehicle sure can feel pull just have have faith completed program got restriction removed licensehowever FAA guy pulling tow release halfway up tow exam flight Wow Would again bet sometime

describes some interesting facts Tow speeds vary little according wind accelerating tow vehicle 45 mph until rope off ground slowing 35 mph rest tow same time glider accelerated 45 mph until rotation increased 60-70 mph depending climb angle reason glider going faster because has vertical speed component added horizontal component plus wind speed like RC glider going up fast winch yet much line
