Tom,

I was working on my 50cc Extra last night (hinging...uugghhh [:'(](shudder)...) and when I pulled my wings from their bags, I noticeed that I must have put just a touch too much presure on the LE of one wing, that I popped the top of a rib in the LE area. If I recall right, it is one bay outboard of the servo...hmmm...right wing. Anyway, I was curious on your thooughts of using something like "Great Stuff" and injecting some in the LE in that area to support the LE sheeting there. I can access the area throough the servo mount, and just a quick squirt will put enough of the expanding foam in to fupport the LE.

I'm not planning on filling the entire LE (tip to root), (why add the weight right?) but I need some support there for longivity. If it were an easily accessable spot, I'd just put the broken piece back in and CyA the thing in strong, but due to it's location, and not wanting to perform full envasive surgery, I figure I can go laparoscopic and fix it from within.

What'da 'ya think?

Jon

P.S. maybe on future runs (I know, modifying the files is a PITA ) the portion of the ribs that is removed could be just a little less, yielding some additional surface area and strength for the LE of the ribs?
