The "P-Series"
The Sky Shark™ P Series Straight Competition Air Frames. These tubes can be cut and ferruled anywhere using a solid carbon rod. They can also be ferruled with any of the New Tapered tubes except the 2PT. These tubes
work great for building sport kites as well as single line kites. All of our P series tubes are non-tapered, with the same inside diameter as tapered tubes. You can join any P series tubes with the tapered tubes. These tubes are made in much the same way as our wrapped tapered tube with the exception of materials used . The P-series also use a different layering of materials which makes it possible to cut the tubes anywhere and ferrule them without breaking out the wall, unlike the tapered tubes. A common question is "what is the difference between P-series tubes and the tapered tubes?" Weight verses stiffness. Example 3pt, at 12.5 grams, has the stiffness of the P-200 at 14.5 grams.Which is more durable? The P200. The 3pt is an ultra light performance tube wind range 2mph to 12 mph or more depending on design. The P-200 could take winds up to over 20 mph and not break. It would lack the performance of a stiffer tube, but can take it, unlike the 3pt. The P series tubes also have a smooth finish and this year come in either a black or the original gray carbon finish except for the p90 and p400 which only come in the grey.
- (Ferrules-- You should always use solid .2400 rod in all tubes with the exception of 2pts, P90s and 2ps which you could use lighter 2400 tube ferrules.)
The "PX Series"
We have a new series of tubes the P1X, P2X and P3X. The new tubes have a new woven look, they are very much the same as the old P series tubes, same ID and OD. The big difference is the tubes are made with a higher modules of carbon which makes them 15 to 20 % stiffer that the old P series tubes.
The "PT Series"
These tapered air frames are exceptional. We have increased stiffness up to 50%. What's the secret? New material combinations! All of the Sky Shark PT series tapered tubes are made on the same mandrels. This means that all of the inside diameters are the same, at .244 I.D. You can use a .2400 or 6mm ferrule across the range.
