Nice article Paul
After Peter Powell, I would add the Rainbow Stunt Kite.
At 9 and 10, I'd note the Neos Omega/Revolution, and the Quadrifoil by Ted Dourghtey.
I might keep the Glite as number 1, its being the first controllable kite on the market that weíve been able to identify.
I agree the Rainbow deserves mention after the Peter Powell but why? It's similar in design to the Peter Powell. By similar Iím pointing out that most all the kites of this period were loosely based off the Rogallo Flexi-Kite. As I mentioned above Rogalloís design was developed in the 1940ís and further developed through the 1950ís & 60ís as a controllable parachute or more accurately a glider and although he experimented with its control features as a kite he never did to my knowledge bring it to market as anything other than a single line kite so although important and inspirational it wasnít widely known.
But nobody has given a reason for including the Rainbow so Iíll give one.
The Rainbow was the first stunt kite packaged as multiple-kites, being sold in 3, 6 & 12 stacks I think. It was surely not the first stunter to be stacked, but the first stack to market. Nothing draws attention like a stack with tails, which drew a lot of attention to kiting so I agree it was an influential kite. I have an original Ediken 6 stack of Rainbows and a spare or two along with a bunch of extra aluminum rods, heavy front frameset, etc.
Another kite worth mentioning in the same era could be the TRLBY, more a true diamond/eddy rather than a Rogallo and able to fly in much lower winds, 5 MPH compared to 10. I flew TRLBY's because the Powellís could seldom be flown here in our inland winds, but I wanted Hyperkites thinking they were the coolest looking. But then the Avenger came to our local store and I soon forgot about these little diamond & delta shaped kites.
Some of the other names at the time? Aerobat, Skynasaur, Sky Cat & Sky-Ro-Gyro, Sky Tiger, Windjammer and Iím sure many more, my first was by Gayla but I donít recall the name.
Pretty sure the Radian was Prism's first kite to market, and a logical evolution. The first succesful Stunt Kites were based off the Rogallo Flexi-Kite which had found another use by the 1970's more in keeping with Rogallo's 1960's developments financed by NASA. It was the basis for the growing sport of Hang Gliding. But by the 1980's Hang Gliders were evolving into high aspect ratio delta's with airfoil shaped wings using battens. How similar is the Radian to those new hang gliders?
