Skyshark II PT Series

Skyshark II PT Series (words from Skyshark)

The New Sky Shark™ PT Series Tapered Competition Air Frames arehere!.
We believe that they are the very best Air Frames available. These new 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.

I want to interject at this point to explain what has transpired in the transition from original Sky Shark to the new series of Sky Shark ll tubes:

2pt at 32.5" -
The old tubes had a build up of material between 10" and 12.75" from the large end . This was done to make the tube stronger where the lower connectors are placed in the leading edge pockets. This was only good if the kite design fit the application of the build up placement. We also built up the small end about 2" to stop any crushing. The tubes always weighed about 8 grams. It is also important to note that there is sometimes a variance of weight on wrapped tubes because the material can vary from batch to batch depending on the resin content. We've stopped putting the upper build up on the tubes. After lots of discussion with flyers it seemed if tubes were breaking they were breaking at the transition from the build-up to the body of the tube. The build up area was causing a stress riser (weak area). We continued with the build up at the tip and we also went to a different material which increased strength. But to keep the tubes as stiff we had to make the new tubes a gram heavier. We also had to do this with the 2p. As far as replacements with the old, you could not tell the difference.
