Re: Are Pulley bridles more tolerant to stretch/shrink?

Just look at the drawing below. no pulley.JPG Let's assume that at this AoA (angle of attack) it is as you describe it. All bridle lines have load. Now imagine the AoA increasing (that is the trailing ed...

Are Pulley bridles more tolerant to stretch/shrink?

reo.JPG My understanding may be wrong and I welcome you to correct it. I paste the bridle of Reo as an example of a non pulley kite. 1) For pulley less kites only one of the A1,A2,A3,A4 carries the load of the front lines (the rest have a very small load that just keeps the shape of the kite) A1 (a...

Re: Moving from Switchblade to FX

... Do some research about how the window works, and what the relation between netto L/D is taking parasitic drag (weight/shape/wetted surface) into account and how that relates to the dynamics of the window. Try searching about towpoints, CoP and thrust in relation to AoA too while you're at it. Y...

Re: How high are you pointing upwind? Are 30° already possible?

But tracks really should be measured only where there is absolutely no current.. hard to find except maybe on an inland lake. I must be missing something, please help me understand it. If you take 2 consecutive upwind tacks from the GPS file, measure their angle between them and divide by 2,don't y...
