If there was a bit of rocker in the board then it may be that the full length and width of the plate did not get pressed down and properly bonded to the board. Looking at the picture I see no residue at the back on either side. Is there any convex to the bottom shape when you look across from the si...

I've built a couple of fuselages with carbon tubes that I made. If it's thinner wall tubing you can add extra wraps in higher stress areas. Also, you don't need to fill the whole thing with filler. Slide in some tight fitting foam plugs and just fill the parts where the mast bonds in or where the wi...

I have low enough body fat that when muscles, (in my case mostly tendons!) pull tight the skin surface can have concave areas that a seal will not perfectly pull tight over. I've not checked the shape of my neck - its harder to see, but it is obvious at my wrist, even with the seal pulled up some. I...

I've probably mentioned this a couple of times before over the years, but here we go again. I should first say yes, sometimes a foil or surfboard is better, but the question here is about twin tips. I build my own boards and have built them with the same rocker, flex and outline curve, but one board...

Thanks for the input on the board. Mine is not as big and chunky as SaulOhio's, but I'll make it a priority to get a smaller, lighter, thinner flatter board sorted out too. What is the difference between the Moses and Slingshot boards... as in can you relate the feel of them to certain physical char...

Cool thanks for the replies. Although I do plan to build a smaller board, I think I can throw together a much smaller rear fin faster! :) If a longer wingspan is harder to roll, which makes sense, does that make it harder to bank and turn too?? I have a 56 cm wingspan and about 3cm of curved anhedra...

Maybe this is a huge question, but I have a few basic questions and am hoping for of the DIYers have played with different parts on foils they have built. It's one thing to compare the feel of two different foils which I'm sure many people have done, but unless you change only one part at a time its...

8 to 10 layers of fiberglass on one side and none on the other? Have you tried putting 4 to 5 on each side and comparing the results? You seem to like to make different things and compare them. I highly recommend you experiment with other layups. The physics tells us that a strong skin on each side ...

If you tilt the mast you will end up changing the AoA of both wings. I don't know if that is a good thing or a bad thing with your setup. It seems if things are working properly then you will have to change the AoA of both so that they are still the same. Is it possible that you are having to keep y...

When hooking to a fixed object, don't disconnect the leash and hold the flying kite just by the unhooked chicken loop. Hmmm... what could possibly go wrong? Why disconnect your 2 connection points before attaching one of them to the anchor? Even when hooking to that log, if you take the leash off, h...
