more info of psycho

regardign the position of knots at the v line split.

on the psycho there are effectively two sets of v lines which correspond to the a's and b's.

if your kite is underflying, as most 9m do on delivery, move the a' knot away from the kite by about 2cm, until kite flys overhead. stop before it front tucks.

once you have this right then set up the b line to give the greatest depower range, you'll find this by trial and error.

this gives you the shallowest possible aoa but the greatest stability and depower range.
if you want to jump higher and harder then let the front knots out a little until the kite does not come overhead. this gives a more powered feeling and less effective depower but bigger jumps.

also remember that the depower effect is not linear on these kites the effect increases in a non-linear fashion ie the last 2 inches of trim strap matter more than the first two inches of bar movement.

In that case the 12.5 should go to 30knots without a problem

Yes - but dry air is more dense than humid air !

The water molecules have lower atomic weight - 18, whereas air (2 Nitrogene and 2 Oxygene) are much heavier - 29.
So the more humid the air is (at the same pressure), the less dense it will be, and lift less.

But the difference is very small - only up to 2% in density, from 0 to 99% humidity in warm air.

Temperature and pressure changes means much more for the lift (density = lift).

Just for the record...

yeh but oxygen and nitrogen are gaseous in the atmosphere and water hangs around as very dense collections of molecules. somewhat negating the density issues.


mm what weighs more, saturated humid air or your more 'dense' dry air.?
