Tigerdude,
I finally got around to looking at your problem with the wing tip plate. Sorry it took me so long to get back to you on this, it's been a hectic day for me. Anyway, I've got your problem figured out. I've posted the answer for your problem in my build thread. I didn't want to post it twice so here is a link to my answers, they are post #77 & #78.

I hope this takes care of you problem. Let me know if there is anything else I can do for you.
