Station #1

[dferr34]

I was thinking of stating with station #1 for a little practice, the overall length of the upper tube is 1/8 longer than the bottom,
Is that correct? I watched a youTube video of a guy fabricating the XL station #1 and he said it was perfectly square.

Thanks,

Are you building a Double Eagle or an XL?

The double Eagle.

I can't figure where you are getting non-square dimensions from. My Double Eagle plans show a Station #1 width of 20" and height of 14". These dimensions are center-to-center. As I understand it, Station #1 is a perfect rectangle, top tubes equal length and side tubes equal length. What page number are you getting the 1/8" difference from?

[dferr34]

I believe its page 29 it's for the motor mounts but I thought it was also for the frame, I was subtracting from both sides the 1 9/16 from the top and the 3/4 from the bottom thinking that would get me the frame size. I guess I shouldn't be using that page.

Pages One & Two show the fuselage tubing dimensions I was referring to. You could probably make Station #1 any dimension as long as the motor mount will fit. I do think it is important, however, to make it a square or a rectangle so all the loads from the longerons, diagonal bracing, and cabanes will enter the Station in a balanced fashion.

Thanks for the help! I have another question. I was reading about the double Eagle's CG is a bit forward and that you should only tack the cabanes incase you need to move the wing forward. Where are the cabanes on the fuselage? And I read they have something to do with the wing strut? I've never heard of that word before. Sorry for the silly questions, I am a private pilot I just never built an airplane!!

The cabanes are the diagonal tubes, front, side, & back that support the wing tube and wing mounts. One other thing to consider is using the XL style wing attach method on the fuselage. It uses separate bolts for each wing (4 bolts total) instead of a single bolt in each fitting holding the wings on (2 bolts total Page 3A). The four-bolt system makes attaching & removing the wings a lot easier. Several parts would need modification but still something to think about. There is an interesting video series on YouTube by Jeremy Dunn about the DE fuselage. Just put "Jeremey Dunn Double Eagle" in the YouTube search box.

Thanks for this info. So I guess moving the cabanes is not a simple thing. I'll checkout the video.

Thanks,
