I got my hands on a decent foil but do not want to shell out $1000 for a board. Has anyone built their own board and if so can you give me some tips. Thanks That's a very interesting topic. I wish there was a wiki or a sticky to summarize all the knowledge that is spread in here... Any volunteers? ...

My wrong, instead of “center of moments” I should have called it the aerodynamic center (wider used term). The point at 1/4 of the chord for our applications. https://www.grc.nasa.gov/www/k-12/airplane/ac.html https://en.wikipedia.org/wiki/Aerodynamic_center (AoA increases, chord gets shorter, AC co...

Again, my understanding is: (and you are welcome to challenge it as this helps me understand better) As you sheet in, the wing tips come forward and the CoM (center of moment) comes forward relative to the LE (while the kite sits deeper), that loads more the front lines and changes the whole geometr...

May the force be with you

Vector analysis on real picture /experiment show that a2 does not carry load, because if it would a1 and al1 would not be parallel!

And off course if "equally loaded" a1 would have the same angle as a2 compared to AL1.
Now one is parallel and the other at right angle!

^Dude. You obviously just want to argue. That's not how kites work. Go tie your kite to a solid object, fully power it up near the ground, go ping the lines. You'll see that they're pretty equally tensioned. Then come back and whine about how the experiment is invalid. Well, I just want to learn an...

And that front view of the Ozone Reo is a frontal projection of the bridle geometry, not a true-view of the A1/A2/AL1 plane, so the angles shown in that frontal projection are not true, but rather projections onto the front view plane. Still if you add all vectors in a (non accelerating) node they ...

Don't "ASS-u-me" just do the vector analysis. It's simple for a string or group of strings. As we say in engineering, "you can't push a rope." Oh, I'm glad that we can talk with vectors! Just take the first drawing (Ozone Reo from the pdf manual) You see that A1 is parallel to AL1 that simply means...

Actually I remember one of your heroes, Greg, saying the same thing like Peter when talking about his board. Do you want me to find it for you?

Yeah, I guess I can be a mean ass. PF has a great contribution to this forum and from this to the HF scene in general. (I'm very grateful for the knowledge he offered here out of his free time) Having followed his posts, I'm quite sure that he's just sharing his opinion and impression and that he w...
