The linkage is to make it automatic. Since its a model the operator is always going to be some distance away. Boat "knows" the wind direction better than the operator and can respond faster. Yes, trailing edge flap is a good idea. But the idea of this is to keep it simple. I have used flaps on other models, connected in opposition to the tailvane movement, works well, but more complicated.
I know what the linkage is for. Just wondering why you didn't go to the same scheme as on the full sized boat for the models. BTW, although it is stalled, I am working on a model using some similar concepts.
Firs response disappeared. I knew there was no servo, just wondering why all the linkage instead of the way you do it on the full sized boat. Ever think about a trailing edge flap, and maybe even a leading edge one, to improve wing L/D and max Cl? If adjusted right, could move in proportion to angle of sail control surface.
Not sure why the vane isn't just stuck on a boom off the back of the sail like an airplane tail. Then you could use a trailing edge flap too, turned the opposite direction off the same servo.
I so admire this effort.... here we see a master tinkerer who has a spot-on design sense and ability to execute. Wow!
I just spent several hours on your websites and looking at all the videos. really terrific!
Thanks! Don't hesitate to ask further questions if there is anything further you don't understand. The website address is www.sailwings.net
nice
thanks!use full for me!

You didn't understand it. There is no servo - it's automatic. Look carefully on the website for how it works.
