I am rebuilding the wingtips of the firestar, and will be using 3/8" tubing for all of the bracing, false rib, instead of the 5/16" and 1/4"

Does anyone have any pics or suggestions from old archives, that show improvements, such as the aluminum renforcing angles on the outboard ribs etc.

Thanks, Chris

Hi Chris,



Really good move streingthening all those areas.  It only adds a few pounds and adds a huge amount of streingth and stiffness.  Here are some pictures of my MK 3 wing with the streingthening you talk about.  



John Hawk is also an expert on improving the streingth and stiffnes of the wings, he is the one that suggested this to me.  



Dont forget to streingthen the wingtips also.  There have been some cases where the weak tips start to flutter and are just very fragile all around.  A few days ago I saw John lift the entire side of is plane up by the wingtip, and it didnt even start to bow or move.  Hope this helps you out.

That looks strong, Michael.

What size is the angle aluminum, & wall thickness? I will at least, do that on the outer rib. Might be a tad overkill for my little 1 seater Firestar.

The picture tells it all.

Thanks Michael

What I meant to say, is it might be a tad overkill to do all the ribs that way.
