"...belittle me for even trying things..." -foilholio
No, that is not my goal. I try to protect newcomers to not to try to invent the wheel again. You don't foilholio seem to understand that there is certain limits in AoA change foils tolerate - and 1:2:4 speedsystem can make it happen within reasonable bar movement. There was perhaps a need for more efficient system for the biggest of kites, but now going to high AR has made it unnecessary, even biggest kites don't have a long chord any more.
I have tried to warn foil kite makers not to stretch cell width too far. If it was a good solution, there would be more kites like that. Trend is opposite, to increase cell count. If it wasn't so beneficial why manufacturers are doing so, increasing complexity, weight and costs of kites?
"I would be highly skeptical of anyone claiming to be an authority or expert, especially some who post anonymously on the internet with no record of there previous work designing kites." -foilholio
I have my own reasons to stay incognito here. That is why I don't present my kites here, except some design pictures. I think it is quite clear that my postings tell I have quite a lot knowledge of kites... It would be strange if I hadn't, I've used years of my life for kites and kiting. It hasn't been at all easy road all the time, but at best a very rewarding one.
"The explanation about autozenith is from Peter Lynn." -foilholio
It is correct, but it is not complete explanation. Peter Lynn of course knows why arcs especially have auto-zenith, but same weight distributed bridled foils don't. So do I, but you don't, foilholio.
I see you couldn't tell from the P4 lineplan why that kite has a variable PA. However your words about changing line lenghts are true, prestreched lines shrink more than stretch.
I think I have much more respectful opinion for pro kite designers than you do. And paradoxally the one you constantly pick up, Greg of BRM, has probably more limited knowledge than designers usually have. That estimate is based on some of his videos where he explains his kites and some other things. Man,that guy talks a lot... But I'm not saying his kites are bad. And of course he knows his kites and he knows what he wants. Technically Clouds are very simple kites.
I don't take seriously your insults, foilholio
You must accept the level of understanding you have. You must study and listen those who know better if you want to improve it. A bit more respect would be good, otherwise I don't know if I bother to help more.
