Re: most visible board color?

When it gets dark your color vision goes south, and everything becomes gray. Your board better be equipped with strobe light.

Also, if only 20% of the board painted red, then it is 5 times less effective.

Re: most visible board color?

We are not distinguishing objects on black background for which green might be the best. Given blue/green background, red is complementary spectrum band to the former two, so it is the best.

Re: Liquid Force Rocket vs Liquid Force Galazy vs Slingshot Dwarfcraft Boards

I have both dwarcraft 4'6" and LF rocket. Rocket is definitely the best to learn: - it is easier to waterstart in lighter wind, - touchdowns are easier to recover, - the board color makes it painless to spot when separated in choppy conditions. Never rode galaxy board, but that hideous dark ultravio...

Re: Best Foil for Absolute Beginner?

As an advanced beginner I recommend wing around 800 cm^2. LF rocket foil is one example. Here is carbon version of it.

Re: Fukushima - isn't it time we started worrying?

There are no less than 270,000,000 kilograms of plastic in the ocean, which is about half a billion pounds plus of plastic. So … is this a big number or a small number?

Re: Wing improvement question

I suspect the glass epoxied without pressure would delaminate pretty easily?

Re: Kiteforum Update 2019 - any suggestions? Site can be offline sometimes!

Thread % rating number which appeared recently is less user friendly than say a red-green bar (e.g. pornhub :oops: ). Alternatively, it can be a line of thumbs up, from 1 to 10, for example, 32% would mean 3 thumbs up.

Re: Snap Shackle problem

I have the same connector on 3 bars. There is cabrinha mushroom safety directly above it. The purpose of this shackle is for swivel and quick connection/disconnection before launching/after landing in normal conditions. I can only think of one way for this to happen. Some sand stuck in the pin eye, ...

Re: Fuselage made with carbón tube

Seal the insert opening with wax. Drill the hole in the fuse. If the insert fits tight, then just epoxying it inside the fuse hole is OK. If it spins, wrap some carbon cloth around the insert. Use the hammer to knock it deep into the hole.

Re: Fuselage mase with carbón tube

You are absolutely right that LF alum fuse is engineered sloppily. Their carbon offering is somewhat better, but still north of 500 grams is too much. I made 2 fuselages from old carbon naish kite bars - 360 and 370 grams: cropped.jpg For wing attachments you need stainless inserts . There is other ...
