Re: Straps or strapless poll

How do you fall with straps? I understand that past beginner level you can anticipate some falls. But what about totally unexpected, like hitting sea weed hidden in murky water? Or people do have quick reflexes?

Re: Foil board compatibility

My only theoretical gripe with track mount is the daily fiddling when mounting. Can you get the little slider bolts to stay put full time? Or do you need to fiddle lining everything up every time to get them threaded before tightening? I’m talking about the lining up of each bolt to its sliding nut...

Re: The joys of valves leaking

The valve does neither have to be hard, nor be exposed to ultraviolet. Valve made of TPU can be hot fused into the bladder. Then, insert PVC pipe from inside and clamp it with another PVC pipe from outside:

Re: Foil board compatibility

It is somewhat surprising that boards with fixed plate mount holes are still alive in the context of healthy 90xTrack competition. Track boards can be relatively thin (e.g. LF Rocket), and if one wants even thinner board, then the solution is as simple as gluing or epoxying foilmount . Therefore, if...

Re: Triple & quad ripstop

I'll be blunt here: doubling (let alone tripling, quadrupling) reinforcement threads is dumb. And who said those threads should be together; why not to space them evenly as windmaker suggested? Conventional wisdom is that large canopy tears are prevented with smaller panels. Understandably, cost-con...

Re: The joys of valves leaking

With all that cost cutting, are Switch Labs still in existence? How about valve heat resistance test: 1. Attach 1 lbs or so weight to the valve 2. Gradually raise the ambient temperature 3. Record the temperature at which the valve is detached It is interesting to know if there is quality variation ...

Re: The joys of valves leaking

This is marketing at its best: "We have quadrupple rip stop; we have max flow tube valve connectors, ...", which doesn't make a shit of difference, but they are completely silent about how durable bladder/valve connections. To me the manufacturing solution to this frustrating leaking valve issue is ...

Re: Suggestions on which "neutral buoyancy" foil to get.

Why would nonsinking foil sit there in place? Wouldn't it rather drift across the wind? Last year somebody actually reported his rig sailing upwind by itself! I personally find the board drifting downwind super nice feature. With kite at 12 want to drift downwind slower than the board? Anchor the bo...

Re: Lateral Flex in aluminum mast

Make sure there is no gap between the plate collar and mast. Otherwise, squeeze some fiberglass into the gap and epoxy it.

For 2016 Rocket mast+collar I measured flex being 14 mm or so in 5 kg test. The 2015 LF mast is thicker and should be even less flexy.

Re: Suggestions on which "neutral buoyancy" foil to get.

If you swap the fuselage to carbon, it would alleviate the LF sinking problem. I have made 350g fuselage, and the foil become much nicer. With those standard 1200 g grossly overbuilt alum fuselages I wonder how competent the designers were.
