I have kinda snookered myself by putting the front threated insert to close to the le.....
Hindsight is a wonderful thing!
I'll stream line as much as possible before cutting ionto the threaded insert thread.
How many layer of carbon on your mast Denis? Or more to the point how much gram layers of carbon?Denisesewa wrote:
In my opinion the profile (airfoil shape) of the mast and wings is most important, my first masts and wings were kind of blunt which caused ventilation issues, which I think is what you mean by stalling?
I can send you paper templates of my current wings if you like,( the ones in the pictures at the top of this page) I built these flat with winglets and curved ( 2 inch drop from center to tips) , the flat wings have a different feel and I personally prefer curved ( anhedral wings ) , my rear wings have about 3/4 inch dihedral. I consider these mid aspect freestyle wings.
The following picture is the profile of my first mast ( on the right) and my current masts( left), the difference in performance is remarkable.
Mast stiffness both lengthwise and torsional have a big impact on stability at speed and in carving turns, a flexi mast delays feedback to the rider so its more difficult to keep up with minor weight adjustments.001.JPG

Cool. Ok. My gut feeling is right then. I'm currently at 1000gm. But only 600gm at the mast/plate connection. Think i'm going to roll another 400 just to be on the safe side..... Plus I expect to hit boulders at some stage so need a strong mast/plate/fuse connections.Denisesewa wrote:plummet wrote:How many layer of carbon on your mast Denis?

It actually depends on what type of carbon I have on hand , the length of the mast and the core material, my first masts were around 1500 g ( 50 + oz) which means you have to start with a very small core, the last one is around 1150g (40oz) and is plenty stiff enough at 34 inches ( 86 CM)
