Hello,  Mighty Brain Trust!!

Can you please tell me the correct recommended length of stack link lines on the following Flexifoil combinations.

Hot Shot to Hot Shot (4') to (4')   Smiley
Hot Shot to Stacker (4') to (6')   Wink
Stacker to Stacker (6') to (6')   Grin
Stacker to Flexifoil 8  (6') to (8')   Undecided
Flexifoil 8 to Flexifoil 8 (8') to (8')   Angry
Flexifoil 8 to Flexifoil 10 (8') to (10')   Sad    and finally,
Flexifoil 10 to Flexifoil 10 (10') to (10')   Lips sealed

As always, your help is greatly appreciated.

Thanks and happy winds to you all.

From Ray Merry's site:

Flexifoil Power Kites are very easy to stack together. The following 4 methods give a range of linking systems from the simplest to a more sophisticated inserted loop method.
As a rough guide it is useful to estimate potential pull by using the Stacker as a standard unit. The average pull of a Stacker is approximately 50lbs. A ProTeam is roughly equal to 2 Stackers and a Super 10, 3 Stackers. Therefore it is relatively easy to get a rough idea of how much pull is likely from a given stack. Of course, pull can go up drastically with wind conditions and kite speed.

Separation for same size Flexifoils
Hot Shot 4 -  30 inches
Stacker 6 -  54 inches
ProTeam 8 -  62 inches
Super 10 -  72 inches
Flying Line strength - wind 10-12 mph
Hot Shot 4 (up to 6 units) - 150lbs
Stacker 6 (up to 6 units) -  200-250lbs
ProTeam 8 (up to 3 units) - 200-250lbs
Super 10 (up to 3 units) - 250-300lbs

When stacking different size Flexifoils, more distance should be allowed between each kite. 72 inches is a good starting point, especially when stacking 6ft and 10ft Flexifoils together. Smaller kites are usually put in front of, or below, the larger sizes. The Hot Shot 4 is not suitable for stacking with other sizes due to its small Wingspan.

You forgot Super 10 to Hyper 12 and Hyper 12 to Hyper 16.  Wink

I normally use the above chart Sam posted, works pretty well.  I used 30" on my Hotshot stacks but they would tend to do strange things - I blame the crappy wind conditions we had at the time.  Still need to add more to see what will happen.

When stacking the larger sizes I don't think a few inches difference from that chart will make much difference, as long as both sides are equal.

Thanks Sam and Mike.  This should be a great start.

You guys are the best!!     Grin

Thanks for the information!
Anybody had experience with link line length between a single stacker and a single ProTeam?

I use the following lengths in cm:
stacker - stacker > 100 cm
stacker - proteam 8 > 140cm
proteam 8 - super 10 > 160

works really well!

I flew a 16' Flexi on 125', 200# lines hoping that On event of a gust of wind one line might break preventing my being dragged.
On the other hand I flew a stack 8',10',12', stumbled, fell and was dragged, bending my rib in the process. I've flown 2-12's on 125',150# lines. It all depends on the wind speed.
