Re: Soloshot3 a New way to film kiting

If you check when you filming with the soloshot you will notice its not the tripod moving. Unfortunately its the horizontal axle in the soloshot (the one that moves the camera vertical)that have play and is to weak. When the 65 camera zooms the weight/windage is to big for the "axle".

Re: Best single strut kite for boosting on foil?

I would say the Ozone Enduro 12. No single strut kite can come even close in boosting and I can easily foil in 8 to 10 on a lift foil.

Re: How much underpressure?

Hi
I use one of these http://www.ebay.com/itm/Vacuum-ejector- ... 1427439751 and its gives you more than enough vacuum. I use a normal compressor or a dive tank (low preassure outlet on the first stage) to power it.Simple and cheap.

Re: Tight fitting rope--how do you thread it through an open

I would use heat shrink tubing for electric wires, simple to get a tight fit.
