Dayhead, after flying a Fledge 2 for 36 years, there's a good reason why I maintain that glider, and still fly it.
It has rudders that act as air brakes. I have numerous stories of how them rudders saved my a** time and time again.
I have been able to parachute that glider (2:1 glide) between trees. When other gliders had no other option than to pick out a soft looking tree, I've been able to deploy both rudders to slow down from a 12:1 glide to a 2:1 glide into a grove of trees and land on the ground without puncturing a wing. In other words, I dropped down into and between trees just like a parachute. The only weight shift is pitch. Combined weight shift and rudder control is tops!
There is one time where I came out of a loop, stalled, and pitched over forward and landed on top of my wing upside down, accelerating into an inverted dive. Too low to throw my chute, I pulled the bar in and deployed one full rudder. The glider rolled right side up just in time to land.
For spot landings, nothing beats a Fledge (in my opinion) for hitting the spot every damn time. You come in hot and apply both rudders as needed, flare hard, dead stop. Every time.
This is a glider made in 1979, and an easy glider for the H2 pilot. It takes 1 to 2 years to master the wing for most flying conditions, but once learned, look out!
If a manufacturer was to come out with a carbon fiber air frame version of that wing, I would mortgage my house to purchase one. It is one tough design that has lasted me all these years. It is fun to fly in turbulence and very satisfying to fly. The performance sucks compared to today's standards, but does nothing to diminish the fun. At 55 pounds of aluminum and dacron sail cloth, I can only guess what a carbon fiber version would weigh in at.
The only down side to the design is you can weight shift the glider into a vertical dive and invert the wing. Control goes negative and then you are upside down, but, with today's engineering, I bet a designer can fix that one flaw.
I'm not chasing records or trying to do much XC. I just like floating around with absolute control and confidence.
