FIrst personal glider was Grob 104 Speed Astir IIb. I learned in Grob
102/103 and it was a smooth transition to the flapped racing ship. It
was a very nice plane. Great legs, easy water ballast, easy to
assemble with a one man rig, and nice looking. I sold it after many
years because the relatively heavy aileron forces gave me shoulder
pain after 4 hours or so of flying. However I earned all my badges
and all my diamonds in that ship.
