A clarification (or maybe an oops?)... the versions of the Falcon56 may have gotten in my mind scrambled up... I'm not so sure anymore when spearate upper and lower spars came into use on the Falcon 56. I had said it was on the MarkII, but it may have been later.

Dr. Dave -- which version are your plans for? I see they still have the single central main wing spar.

For nostalgia buffs... here's a scan of the birdie for the tail feathers. I can't remember any longer whether he's supposed to be white or yellow, but here he is to transfer to the covering color of your choice if you need him to complete a covering job like the prototype... a shot of the tail to get the original shape, and finally how to do the linkages if you're using escapements. Check the nylon fabric hinges, too... much more convenient than those ol' thread hinges!
