Hey All....Hope everyone is doing well. I seem to have misplaced my manual on this kite and was wondering if anyone has experience on tuning the kite for various conditions? The brake lines have several "knot" positions (DTS?) and to date, I have been using the middle most position. I can't remember if you go down a knot (s) or up for high wind....

I'm starting to get to the point where I have enough experience with the thing that "tuning" it is starting to come into play.

The Beamer TSR Field card can be found here:
http://www.powerkites.de/images/stories/manuals/fc_beamer_ts...

Basically,

adjustment knot closest to the bridles = speed
adjustment knot in the middle = neutral
adjustment knot closest to the flying lines = power

There are detailed diagrams on page 3 and there is also some graphics that depict the relative tradeoffs in Speed, Power, Stability and Backstall ability.

Hope that helps.

ATB,
Sam

Thanks Sam! That was exactly what I needed.....

For the brake bridle adjustments, go tighter (closer to the kite) for higher winds and loose for lighter winds.

Got it Angus...Thanks. Just out of curiosity, is this similar to a de-power in brake line adjustment where as a de-power can be adjusted on the fly with the bar as opposed to landing the kite and manually moving the brake lines to different rear bridle knot positions?

Kind of. With a de-power foil, the rear lines connect to the outside of the bar and the front lines to the center, bass- ackwards from your TSR. Also, de-power foils have a pulley system on the main bridles so that rather than just deflect the trailing edge, the entire canopy rotates in order to vary the angle of attack across a wider range than you would get by just deflecting the trailing edge. Simple schematic here...

Most modern de-power foils have dual pulleys on each side working with a compound effect through a mixer system that not only rotates the canopy but varies the chamber of the foil.

The Phantom that I was trying to fly with you the other day in the dying winds at Jekyll Is. has no bridle to speak of nor pulleys; rather pulling in on the rear lines serves to rotate the canopy off of the front lines to change AoA. Modern twinskin/ Arcs have pulleys in the simple bridles but they serve to offer mechanical advantage to either reduce bar pressure or increase de-power range. Similar to LEI's in that regard

I see....These kite designers are a very intelligent group of people. My hats off to them. That's incredible how they design these things. Thanks again for the detailed explanation. I have a good grasp on it now. From my student pilot lessons and helicopter blade/head/tracking and balancing maintenance experience it all makes perfect sense. AoA....

Or more precisely, AoA and an efficient way of controlling it in regards to the air foil that we all seem to love to have in our hands/hooked in..
