In 1989, Peter Powell brought the Double Diamond (or "Double D" for short) on the market. Essentially two Stunters side-by-side, with their joint cross spars forming the leading edge of the quad. This design created a problem, as it was deemed to be too similar to the new Revolution quad, and Peter Powell Kites were forced to take the "Double D" off the market within two years of its introduction.
In 1991, they came back with an alternate design, named the Omni. The two Stunters were rotated 90 degrees, and positioned tail-to-tail, such that their joined spines now formed the long cross spar of the quad.
Needless to say, I had to add an Omni to my collection, and I'm happy to announce that I have succeeded in that. Meet my green-fluorescent-and-black Omni! Its previous owner lives on Hawaii, so a bit of a shock for the kite to find itself out in the British winter ...
So how does it fly? Well, it turns out to be a very twitchy kite, and it took me quite a while to get it under control; it tends to oversteer a lot. But with the 'arrows' on the kites, indicating which side is 'up' and 'right', it's certainly a striking kite in the sky!
Having managed to get one of both the Peter Powell quads, we of course had to try them both together. Not with the aim of a pair routine, but simply to compare their flight characteristics in the same wind conditions (4-10mph).
Besides the general shape, the Omni is also smaller (1.83m wing span) than the "Double D" (2.16m wing span).
Even though the Omni was advertised as an 'improved version' of the PP quad line kite in a 1991 catalogue, I must say the earlier "Double D" handles much much better. Far less twitchy, much more stable, much easier to control. It is a coincidence that the kite more similar to a Rev handles much better?
By the way, I doubt many pictures exist showing a Double D and Omni together in the sky!
