Sorry PF for not being clear but you smart guys out there already have the answer.
When we talk of wing profiles we say 90% to mean it is thinner ONLY on the thickness and we know we change the TRUE naca specs but we feel thinner should be better?
Meaning that if a given NACA is 10 thick we do 9 or sometimes even thinner.
We could be very wrong here........just seems logical that "thinner struts, fuses and wings should be more hydrodynamic?
But Tom Speer probably knows better according to the numbers concerning his 105.
As we hand make all our molds and wings we spend a lot of time on them.
Bye the way a at least for us, a nice find.........quadaxial carbon.........just seems better and each layer after vac sac comes out 1mm so we start to precut our layups for more presion and less filing and sanding.
We have looked into 3d printing and cnc milling but beyond our budget now.
We have found a Very inexpensive solution that will be our winter project.
A simple home made 3 axis mold cutter for use with hard foam to make one time use molds.
I will post findings.
On an off note,
We had the fine chance to play with the (in my and many others who know) first true foil innovator
and rode a front wing he made at 350 cm2 and stab at about 200cm2 with a most stiff strut and fuse.
What a F/&%")= PLEASURE talk about the sensation of gliss, sorry french term, shall I say slicing thru the H20!
And for the third time flew the 15m2 chrono and I absolutely, positivly would buy either that or a 12m2 for the light and up wind is unreel!
I have found nothing new as most racers already know this, just chiming in.
FOIL + FOIL!!!
Other real life flying test result.
Moustach (wing tips angled up) stabs simply work better than flat, even with vert TT style fin, and rear wing, stab AOA does play a most critical role, even half a degree can be felt.
After reading "how wings work" I am now intrested in the Coanda profiles and because the bottom is almost flat will be easyer to mold and shape.
See the Coanda 3, I have to think for "normal" foiling this should be just fine, Thoughts?
