JohnIn his article, Jack states that this is "an impression of the design rather than a scale attempt." Nevertheless, the design will pass as a Hurricane as a semi-scale stunter as well as most other semi-scale ships of the period. I am not aware of any "good stand-off scale as well as a 'stunt-worthy'" Hurricane in the fashion of a Rabe or a Burn super semi-scale stunter. Jack's version had a Fox 35.
Jack's article does not give specifications though he does mention that his weighed 36 oz with the an old tired Fox 35, no muffler. Taking dimensions from the magazine plans:
Span: 49 inches
Area: something around 540 sq in or maybe slightly less
Flaps: something around 85 sq in or just less than 16%
Tail Span: 22 inches
Tail Area: something around 115 sq in or slightly less or about 21%
9 inch nose from prop driver to root LE
15 inches from HL to HL
Nice looking airfoil, or typical of Sheeks designs.
Wing construction is classic C-Tube
Built up vertical and horizontal tail surfaces with lots of ribs
Fuselage has stringer aft of the cocpit.
Very narrow fuselage. Uses a 2 inch spinner and the fuselage is no wider than this 2 inch spinner
Gives definite Hurricane appearance.
Hope this helps.

The Sheeks version looks pretty good in RSM's illustration though smallish at 50" span. The Palmer version has a great semi scale look and is around 54" or so. The airfoil may be thinner however. The Sheeks version may have been an I beamer(?)but this is not mentioned in the RSM materials so it may have been changed to conventional construction as was done with the RSM Skylark.
The Palmer Hurricane likely employs the Palmer vertical spar which would likely be retained if it is, in fact, ever kitted by Brodak as the Smoothie and T bird both retained the vertical spar.
It would be a simple matter to convert to C tube with web spar construction retaining the same airfoil if you liked either cutting and sanding the ribs in a conventional fashion or having them laser cut. The rest should fall into place using modern construction. Alternately, an acceptable cored foam wing may be available from Jim Pearson or others for the approximate cost of having the ribs laser cut. The foam wing will likely cause a weight penalty but does have some potentally offsetting virtues if weight is not a big issue.
Without the luxury of looking at both sets of plansI would be inclined to go with the Palmer version refashioning and cutting my own ribs as a C tube/web spar as it is larger and classic legal and definitely has a nice scale look. Brodak stick on Brit insignia, etc. should still be large enough to look OK. A real good fit for a Brodak 40 I would think if the weight was not overly heavy.
This is a real nit-pic and about as important as an eyelash on a gnat, but post #5 on Jack Sheeks' Hurricane was on 5 August at 10:59PM. Your post #12 was on 6 August at 11:34 AM. Unless there is some kind of time warp around Guthrie OK, post #5 was about 12 hours and 35 minutes before post #12.

By most informative post, I was referring to Keith's post #18 describing wing construction methods, etc. This post did, in fact, occur after my post #12. Not to be nit picky or anything.
The Stab/Elev area are fine for stunt but way too large for scale. I thought we were trying to get a good stunt plane with a semi-scale apperance. I sure like mine. Both of them fly way better than I do.
Brodak is coming out with Mr. Palmer's classic legal design but it probably won't be available until next Spring. So Cane fans, hold your jets and don't get your shorts in a wad. A really good one is coming.
