Re: Bandit 8th edition bladder question

During a screening leak test ( kite pumped hard & coated with soapy water ) the air will leak out the nearest hole in the Dacron. Often that's a stitching hole at the LE closure seam, canopy-LE seam, or another spot with stitching. Leak will typically be in that general area.

Re: Bandit 8th edition bladder question

To find the super tiny pinholes, you need to inflate the bladder in sections between the 1-pump valves. This will allow you to pump up that section of bladder to super drum tight pretty well across the section, stretching the bladder maybe 15 - 20 % circumferentially and opening up those tiny holes....

Re: Bandit 8th edition bladder question

Highly doubt your patches are leaking unless you didn't clean the bladder before applying the patches and they have come off during re-installation. Might want to check on the old bladder the location of some of the new pinholes. If they are repeatably close to the original ones ( same pattern ) the...

Saw that but with a human at the controls the steering and sheeting inputs won't be as repeatable as having a machine at the controls.

Re: Enter the world of Duotone

Back in 1987, Gaastra, Bruce Peterson, Dave Russell, Jeff Magnan,Chuck Stahl and others developed and tested new windsurfing sails with the ADTR test rig, which apparently gave the first indications of the benefit of a loose leach sail and helped Pascal Maka win back the sailing speed record from Cr...

Re: Enter the world of Duotone

This video made my day, 1 min:28 sec into this video, they show an instrumented kite flying / test rig being towed behind a small van. Finally ! The ability to test kites empirically instead of by subjective / comparative test riding. Want to know more about this test rig, particularly if it only ca...

Re: OR Soul Seepage

Sometimes wrist burps/leaks happen when body-dragging upwind. Keep your forward / outstretched arm a little lower, below your shoulder to minimize the amount of air in that sleeve. When you switch hands, slowly put the new front hand down slowly under-water before reaching out with it, to push the a...

Re: OR Soul Seepage

But if there is some trick to fix Soul seal leaks, I'm all ears. A clean shave of your neck area will improve the static performance of the neck seal. On all seals, moving them down or inward to a larger circumference position on your neck/wrist/ankle will tighten up the seal and increase its resis...
