enlarge 56KB, 640x529 2 1974 - The phrunobulax was my first original hang glider design. Loosely based on Dave Kronk's wing. It used spoilerons for roll and turn control.
enlarge 74KB, 640x458 3 1975 - The Tempest was my 2nd original design. I buiilt it while working for Dan Johnson at Firecraft in Chicago. Inspired by the Princeton sailwing concept from Mike Markowski in Scientific American.
enlarge 67KB, 640x459 4 1975 - The Tempest being test flown at Mt. Trashmore in James Park, Evanston, IL.
enlarge 59KB, 640x486 5 1976 - I built the Dart in one night from the remnants of the Tempest. 30' wingspan. Very manueverable. Decent glide ratio depending on the airfoil.
enlarge 43KB, 640x484 6 1975 - 8' scale model of a 42' concept. It flew great! In early 1976 I built a 36' version with joystick billow shift and other features.

enlarge 88KB, 640x437 8 1976 - Hobbie Hawk R/C sailplane on high start lauch. I loved this glider. I did a lot of thermalling with it. It was a joy to fly and tricky to land with no spoilers. "Jonathan,

enlarge 54KB, 640x521 17 May, 1978 - White Tailed Dart v2 flown by yours truly at Warren Dunes. Note the cardboard V tail duct taped to the rear rigging.
enlarge 106KB, 495x640 18 May 1979 issue of Hang Gliding Magazine had a small bite about the WTD. I got a few responses from around the world from this little spot. Copyright 1979 USHPA.

enlarge 44KB, 640x424 21 5/1979 - Warren Dunes, MI. Typical spring/summer day. I'm on top waiting to launch.
enlarge 46KB, 640x495 22 White Tailed Dart v3. This was the best flying version before I rebuilt it.
enlarge 42KB, 640x484 23 White Tailed Dart v4. 34' span. Rebuilt from v3. Great potential but was never fully developed.
enlarge 43KB, 640x496 24 1979 - White Tailed Dart v4 test flight at Mt. Thrashmore.

enlarge 22KB, 640x437 27 1981 - Moyes Mega II with Soarmaster power unit on landing approach in friend's backyard in Barrington, IL
enlarge 30KB, 640x437 28 At the point of no return. The neighbor's yard was much bigger but I just made my choice!
enlarge 28KB, 640x437 29 Final approach. Landing at dusk in high humidity. Stall speed had increased to 22 mph
enlarge 35KB, 640x437 30 I was heading straight for a thorny bush so dove at it.
enlarge 44KB, 640x437 31 I flared out just over the top of the bush
enlarge 39KB, 640x437 32 Landing at 22 mph I couldn't run out and had to let it roll out, stopping 3' from the property line hedges.
enlarge 42KB, 640x437 33 What a relief to have landed safely in a tight squeeze at dusk
enlarge 45KB, 640x437 34 That's Eddie who drove home and told his mom what I was about to do.
enlarge 59KB, 640x433 35 Me in my 'Eipper diaper'. Mosquitoes immediately began chowing down on me. Thanks to Midge Bohlke whereever you are for taking these!!!
enlarge 39KB, 640x379 36 4/7/08 - The venerable Swag-It Tool for Nicopress sleeves that I bought from Eipper-Formance in 1972 or 3. I built a lot of gliders with it and if I had kids, they'd inherit it one day. I just donated it to Ken de Russy for his museum. "In 1975 we and Hang Glider W..." View Comments...
enlarge 86KB, 640x616 37 1982 - Moyes Mega II, just before I sold it. This was my last hang glider. I had converted it to double surface at one point and it flew much better than stock. I had many wonderful flights along the Lake Michigan sand dunes from 1980 through 1982. "Where, while flying one day ..." "That was Larry Mansberger wh..." View Comments...
