Hi Tadeusz, I think what you said is more or less what I also feel. I control speed same as on a normal foil by course and kite position. The named 80 cm (span) foil from Gong was not directly to big for my 63 kg, but hard to start with small pocket boards. I will experiment with big wings a bit more, as I think in their case the usage as monofoil, could reach higher speeds than with a stabi, which pushs the wing into high AoA position, all in respect to their overall low speedrange for sure.
But apart from this and maybe some wave and pumping experiments for me small wings are more interesting, as more speed, lively, adrenalin and also easier to go faster and therefore also jump higher. At speeds small wings profit to create not as much extra lift as big wings when pitching up to much, so you have a chance to push front foot down again, before the for big wings pretty violent front food pressure overwhelms you.
@fun2kite & downunder:
Don't worry, all forces at all components will always be significant lower on a monofoil including also all possible fails, due to several effects, mostly already described.
@ronnie: Thanks for great explanation
There is maybe just one small effect against structure stability:
A monofoil is a bit more sensible to flexible parts, especially boards and wingtips. But on the end all parts which have been noticed as too flexible has been also seen as bad for stabifoiling. The biggest difference is that on a monofoil you can more clearly name the bad parts, as I can with some to soft boards/worn board fundaments and coming to wings for sure the kite foil 65 cm wing from Gong, which you just have to take in hand to see, that it is thin (ca. 15 mm glass and carbon) and therefore to soft at this span.
Great work, I think you build the worlds first monofoil only wing
And it looks pretty much perfect to me.
A few small things maybe could be improved:
- If you start to ride faster try to put the strut more forward under the board, you will feel this when bending your back leg more and more at speeds which costs force
- the end of the fuse being a bit longer reduced in a flatter angle could create a bit less drag, but this part is always a compromise, my idea is to use added ends out of softer materials that can be exchanged, when worn after putting them on the ground as in your picture.
Try to find somebody to buy your old foils, as it could happend that you never want to go back
Oh and let's hope that hatchet handle never remembers its original purpose
