It's best to just bite the bullet and get a B standard package with extra frame (2 and 3 wrap) and all. Then you will need a B vented package, also with two frames (3 and 4 wrap). At that point you will be able to fly in any wind in which you care to stand. Yes, lots of $$$, but in the end, a very good way to go.
I understand that they are available at REI, but have not checked that out.
We went to the park yesterday and gave them a try. This was our first try. I neglected to raise my head high enough when the kites were high in the sky. Easy to correct. Due to the preset camera resolution, the files are very large, but can be converted to other formats and made smaller. When that is done, the picture is not as crisp, but still very good. Here is a clip of our first try. This clip is at the higher resoulution, so I made it only 30 seconds.
The way I learned to do this is to fly forwards across the wind window, then about half way through, I spin 180 degrees and continue flying, but now in reverse. I kept doing this and every once and a while adding another spin. Eventually you will get it to where you will cartwheel all across the window.
I think Watty has it.
Another way is to turn 1/4 turn at a time as you slide across the window, making only one complete turn. Once you have that going, add 1/4 turn each pass. All done very slowly.
There is no one, sure, easy way. I think the most important thing is to not try to do too much all at once. Break it into small bites, you know, the way you eat an Elephant.
In this case, a fillet would act as a wedge, tending to split the outer spar if it is jammed hard against the joint (as in an "end-crash" against the ground).
There is one other thing you should check. Inspect the end of the spar that was over the ferrule that slipped inside,, as it may have breaks or splits in it. If it has, it can be repaired with a little epoxy on the inside, and can be used any place in the frame except where that end would slide over a ferrule.
