Okay I must profusely apologize for these horrible photos, they are horrible. I had a chance to show a demo of how I did the "Y" shape rigging.....

Here are my two pieces of fine EZ line.....

Tied them in a simple knot

Hold two of the lines together, these are the two I glued inside of the engine access panel

Voila! The two in the clamps are the ones I passed through the top wing and staked. As you can see once the bottom two lines that are held together are pulled so tight you can't tell that they are really two lines side by side, they just appear as one. If I did it again, I would try to put them through an eyelet and pass them through a tube like I did for all the rest. That is up to you, but I think this is a pretty easy way to do this "Y" rigging. Make sure you leave plenty of slack for the two arms.
I got some work done, this weekend. I should have another update soon.
Sorry for these horrible pictures again.....
