slightly greater weight long wing offset additional lift climb rate perceptibly changed As glide long wing definitely has increased L/D very low sink rate found long-wing Aria would respond faint lift Aria trimmed fly straight ahead start would tend turn either way lift its own may subtle indication stability slightly reduced long wing model aggressive soarer thermal seeker Another small difference flight characteristics long wing tends make flatter turns short-wing version Mulling later Bill concluded bigger wing flies slowly because has both lift drag though sink less short wing lower bank angle turns another factor increased flight time Wheeling like sea gull Bill remarked wanting exceed BEC time decided bring first flight down within 15 minutes testing flaps way down Flap full pitch
