Just found this Which supports my claim that there was a HYPER 16 Flexifoil Hyper 16 spars

1) Flexifoil system of Theodor Schmidt. I started many years ago using six 2m (6' Stacker) Flexifoils, which worked well but needed quite a bit of wind and were difficult to launch single-handed. I then built a spring-loaded double reel, which helped a bit, making it easy to wind the lines back after use, simply by walking towards the kites on the ground.
Experiments with small parafoils, sled kites, and Stewkie inflated kites showed the importance of having a system where pull can be decreased immediately, especially as the wind tends to be strongest just where you want to stop; on mountain tops. The forward drive of the Flexifoils is, of course, quickly decreased by putting them in the overhead position or landing them. Many other kites tend to continue pulling on the land, making retrieval difficult or dangerous. One or two 3m Flexifoils (Super 10s) worked much better, but still needed quite a bit of wind. I tried a 5m Flexi (Hyper 16) which could be used in very little wind, but was difficult and even dangerous to handle in strong winds and difficult to control without a very long control bar.
I asked Ray Merry to make me an intermediate size, 4m, which we called the Special 13. (This kite has recently become a standard Flexifoil size-replacing the Hyper 16 kite-ed) This was the answer: the kite behaved beautifully in both light and strong winds and was well steerable with my control bar the length of two ski poles. The system now consists of two 35mm diameter alloy tubes used as ski poles and to store the kite spars when skiing downhill and a double reel which fits in the middle and contains some bracing wires which go to a simple waist belt with a quick release. The twin kite lines go through fishing type guides and through two pulleys at the ends of the control bar. The kite is launched right off the control bar, continually steering while the lines run out and while braking the reel with gloves sporting Kevlar patches. Although the kite could be wound down after skiing, it is much easier to land it and wind it in on the ground.
