Are the compression struts installed on both sides of the ribs at each location, or just one side?
To overview the compression struts you need:
From the Forum "News" bar click msg 15985 read msgs and then print out the .pdf file...
Turn to plans page 30 and 30A - review these two pages and the .pdf prints...
Note that:
1) Compression struts are at 4 rib stations...
2) The diagonals & struts nest - you need to loose fit both and glue as one... You might be racking the wing to get in position...
3) The compression struts are on one side of the ribs only... Other Eagle wings may differ!
