Title: Looking for an Answer
Post by: Jim Pollock on March 18, 2010, 05:11:09 PM

Hello,

I happen to have "Dixon's" copy of the large Gypsy plans.  I have a question about them.  They show the wing as having a 55" Span.  I always thought the span to be 56"  With 28.5 inches inboard and 27.5 Inches outboard.
What the plans show is 28" inboard and 27" Outboard.  Which way is correct?  I don't have a copy of the Magazine article to know which is correct.

Someone please help!

Jim: I have the Gypsy 46 plans from Flying Models Magazine but not the article. Using my trusty measuring tape I measure the outboard wing at 27 1/2" and the inboard wing 28 1/2" for a total of 56". I would trust these plans more than the other ones you have as I believe Alan Brickhaus worked closely with Jim Silhavy on making them as accurate as possible.  8)

Thanks Pete,

That's what I thought it should be.  Now to adjust the plans I have to get the correct wingspan.

Jim Pollock,  I guess I should have known.......  VD~  n~

Yup Clint, I thought it would be an apprporiate time (March/VSC) to put that one up. Jim: hope you make the Gypsy, one of my favorites, If you get ribs lazar cut somewhere let me know, I'd like to have a set for future reference.  8)

Well,

I have figured out what to do.  The Rib spacing is said to be 2 1/16".  I checked and 2 1/8" works out perfectly to a 28 1/2" inboard wing.  Just use the same spacing on the outboard wing and cut 1/2 of the last rib section out and wa-la you then have a 1 1/16" difference, good enough for make-up work!
