Hello All, so the p-40 went to the back burner and have been working on a pathfinder. Couple questions, first, shear web,  yea or nea? And the adjustable leadout has a nylon slide, should it be bushed with metal leadout guides or is the nylon ok? Thanks, Jack

Jack, I usually use a truss style of shear webbing to the bay past the gear mounts. I'll often laminate a 1/4" strip of .007 CF between the top of the spar, and the sheeting. sandwiching it in betgween these two structural members really increases the stregnth without a huge weight penalty.

I tend to use the nylon alone, and have never wore out a leadout assy. Your choice, as bushing can help keep the leadouts from rubbing on the leadout slot.

Cheers 

Thanks for your input. John, not following the 1/4" carbon fiber. Do you you run the lenght of spar? And Mark, haven't bailed, just being cautious. Was trying to figure the best way to Build Up the fuse and how to remove that material. Router? #11 exacto? It's in the living room, so I can't ignore it. It's just sitting there, snarling at me. Jack

John, thanks, do you use epoxy or ? And might you have had a little something to do with this plane?  Thanks Jack

Thanks John for info and history. Very cool. Jack
