Your $20 or $30 goes a long way to further the List operation and keep the bills paid. A Lister wrote a funny message in the comments field of his Contribution that I thought summed things up pretty well: "Worth every penny and I'm a tightwad!" Thank you to everyone that has made a Contribution so far this year! It is greatly appreciated.

I have the new CAD GN-1 plans and the only place where I can find that the grain matters is on the nose rib, unless the hatching on the gussets is supposed to represent grain. Initially I thought it was just a standard 45deg hatch pattern to show where the gussets were. Looking closere some of the patterns are less or more than 45deg. I cut out all of my gussets for the tail without regard for grain direction to save material. I have also assembled the rudder and vs with these pieces. What should I do. I am using the GL2 birch plywood from ACS.

Having said that, I would say that it almost certainly doesn't matter, since it would be difficult to predict the direction of the loading stress on the tail structure. Birch is considerably stronger than mahogany, which is what many people (myself included) use on the tail, to save weight. When I had a forced landing about this time last year, one of the areas that received a lot of damage was the horizontal stabilizer, which I ended up totally replacing with a new one. The stabilizer impacted the side of a ditch, and the right leading edge and spar broke in two places, each. The right trailing edge broke in one place. None of the mahogany plywood gussets broke. In general, I lined up the grain of my gussets with the long axis of the gusset.

The Flying And Glider Manual drawings on page 17 give a dimension of 3/32" from the lower bolt holes to the fold line. Obviously this is incorrect, what measurement have you guys used? Whist we're on the subject, how are the slots for this fitting accurately cut into the fuse floor? Thanks in advance.

I will turn those upper attach bolts around to face heads forward. On the strut attach bolts, I did that intentionally. Notice that the bolts are extra long, they are grade 8. They are to hold the tie down ropes. I had this discussion with the DAR and an FAA inspecting supervisor and both approved. I appreciate much anytime when something that appears wrong is pointed out.
