Divine Secrets of the Bluff Park Gliderhood

Ever wonder how those remote control gliders work? You know, the ones that you see at beaches and parks on windy days? Well, I was taking a stroll along Long Beach's beautiful Bluff Park the other day and ran into John, a glider pilot extraordinaire. They seem so real! I was amazed at how these expert pilots control the roll, pitch and yaw of their fragile contraptions with delicate hand/eye coordination. John gave me a great lesson on how the receivers (chips), elevators, ailerons, frequencies, mixers & servos all work together. The pilots generally gather towards the east end of Bluff Park, because it's easy to recover downed aircraft, plus the great updrafts. They have a "wind sock" to tell the speed and direction of the wind, although that hardly seems necessary most of the time. Every so often, one of these birds flies too close to the sun...not to worry, they seem to come out of it OK. Back on their wings in no time! Most of these gliders are made from EPP (expanded polypropylene), not surprising when you realize that a guy named Zagi, who made boogie boards, invented these. Check out www.Zagi.com for more information on glider styles. I really want to thank John for showing me the ropes. Stop by Bluff Park on the weekend, towards the east end, and say "Hi!" He's probably there most weekends.
