Re: Ozone Alpha V1 - First Session

12 alpha vs. 12 ultra?, can you spill the beans plz :naughty: You can find a bit more here http://www.blastkiteboarding.co.uk/forum/viewtopic.php?f=3&t=1513&start=15 I had a quick fly of the Alpha. It seemed to be a heavier build than the Ultra, so I guess it rather depends what you want it for. Fo...

Re: High Pressure kite by Bruno Legaignoux

2) Smaller diameter = smaller surface area so less Dacron (linear relationship) you forget the factor pi = 3,141 12 cm have a circumference of 12 X 3,141 = 37,692 cm 8 cm have a circumference of 8 X 3,141 = 25,128 cm No linear relationship By the way the problem up till now was NOT the material but...

Re: High Pressure kite by Bruno Legaignoux

For what it’s worth, by my calculations, the ‘rigidity’ will be a function of: Pressure * radius (or diameter) cubed.
Thus an 8cm tube will require 3.375 * the pressure of a 12cm tube. (12cubed/8cubed).

As others have said..this type of shackle should NOT be used as a safety release. Have you actually tried to release under even moderat...

Re: Camrig Gen4 for GoPro Hero-6

I’m also a big fan of the ugo mount. Started off with a beastmount but that broke on the 1st outing :cry: Only issue I had with ugo is sometimes the inserts are hard to remove, particularly with cold fingers (probably because a bit of sand has got in). I’ve resolved this by drilling the ends and att...
