Just wanted to mention this is a picture of the very "first" Dawn being flown by it's designer and company owner, Richard "Dick" Boone.
Surprised him to find this on the net, let alone a non-us site.
Dick Boone designed this and many other inovative gliders. He should be credited for much of the design work that came out of Bill Bennetts company Delta Wing. Dick was an early inovator in the sport, and many of his ideas are credited to other companies. He does not get the credit he deserves for helping this sport progress in the early years.
Dick Boone made some beautiful gliders. I had a Dawn (156?)and liked it very much. You could pack the struts up into the sail without detaching them, so the setup was fast.They had no special flight aspects that I can recall.
I own the black comp in your pics, have several dawns including a brand new never flown one, I would be glad to send more pics, I still fly the comp and my 175 big one.
I was a friend of Dicks' back in the 70s & 80s. Flew this glider and many more of designs.
Interesting, never knew about it. I designed and built and flew strutted hangglider in 1983.
i put struts on my rogallo sl cohen 220 back in the mid 1970's in canberra australia and i still recon its a better way than topless cross bars less sophistication for a small price in drag i saw the french gye at buffalo victoria australia 1986 nationals fly his version of a topless with struts before topless came out it seems every one is on a trip were even if it is one ounce of drag they will go for it and pay ten times the price its not gliding its the upper class image and expence .. there is many ways to reduce drag but it has to be their way ..i desinged triple surface to lower camber o the bottom surface by foam padding for moyes csx named after me but give it ten years he might spend money on it .. skeatesy
i recon small struts upfront ..to half of the forward keel section ..and down to half way on the a-frame ..would do too.. and allow the rear keel section reflex.. act like supension as the outer wing tips do ..so the reflex is inline with the flex of the leading outer edges do.. i tryed this and it is yaw stable.. and after you do it you realise present hangliders are still unstable in yaw ..but with suspension keel the whole glider suddenly goes straight ahead..and tim travers [deseased] australian champion flew my suspension keel.. and was amazed ..but trying to get moyes to put it in a production glider is impossible ..because of satus quo.. and parking on the rear keel still needs to be satisfied .. skeatesy
