Re: Another DIY foil

You do not really need to trace splines over airfoil images. Almost all CAD tools can import a list of coordinates into a spline, and do does SolidWorks.

Re: Another DIY foil

Hi Kosta, Awesome thread! I myself was considering 3d printing some wings. I know epoxy does not bond to PLA, but how about ABS or HIPS ? For a recreational foil, I guess one can get away with an imperfect wing profile. Also, how do you decide how much to thin a profile, and why at all? Thanks for s...

Re: Any waterproof bluetooth headphones out there?

I have the Sony Mp3 player with bluetooth. I use it to listen to music using it's internal memory.

Re: Apple Watch Series 2...

Re: Apple Watch Series 2...

Cool app! Will try it next time I kite. One problem I noticed is that, even though you can change units via the phone app, on the watch it still shows imperial units.

BTW, can you comment on the jump height accuracy compared to xensr device?

Re: What to look when buying a second kite for your set?

Hi the 9m Bandit is a sweet kite. My wife rides it all the time, and I do too when the wind picks up. As for trying another brand, the bandit bar has a higher Y split. So not all kites may work well with that. Also you'll definitely need some pigtails to reverse loops/knots. Another brand that has a...

Re: Water starting Technique different?? Short Mast vs Long??

With a longer mast it's harder to tilt the board onto its side. I put my knee on the closer rail, and pull the other rail towards me.

Foot hook covered with that foam and shaped with a belt sander.
If you have one, a belt sander eats away that foam smoothly, and quickly.

Re: Building a Plywood Shinnster / BRM Paipo

Imo, two 4mm layers should be enough with some fiberglass. If you add a bit of concave, it'll probably be stiff enough with minimal amount of glass.
