Sunderland wing question........

Postby seawings » Mon Dec 29, 2014 10:21 am

Guys,

Does anyone know what the dihedral is on the Sunderland wing, in degrees?

Reason I ask is that I'm building the 1/32 vac-form Sunderland kit and am now thinking about how to join the wings to the hull; it's a monster of a kit, fighting me all the way. I've got brass rectangular tube; big one for going across the hull and a slightly smaller one for each wing so that it just slides inside the main hull one and forms a strong joint, along with other fixings. But, I need to set the wings right and am thinking of cutting the hull apart and join the upper wing section of that to the wings off the hull, then fit them all together when set.

Well, something like that.......
Best Regards,

Hi Bryan,

Hope you are coontinuing to enjoy the Festive Season along with your Birthday celebrations? :D

To answer your question, both the Mk I/III Sunderland Manuals state that the Dihedral are measured along the top of the wings, and in front of the Main spar booms.

The Mk III manual gives: 0 degrees 51'

The Mk I manual gives 0 degrees 51' (with +/- 30')

Not sure how 51' will read in 1/32 scale, should not amount to much

Hope that helps?

Regards

Alan

Hi Alan,

I thought to myself that it would be you that came back on this one - thanks so much and compliments of the season to you all down there..!

From a 1/32 scale model point of view, that's wings level in my book! Or, at least no droop.....

It's quite surprising just how big the wings are in 1/32 scale and also what the weigh - I've strengthened them on the interior and had to go the brass rectangular bar route with one sliding in the other rather than the balsa spars I had planned. It's a big bugger all round....

Many thnaks, Alan,
Best Regards,

I would have rounded it off to zero for any scale short of full. Something I read once (and it might have been John Sizer's plans) said the top of the wing was flat across, and the only dihedral was on the bottom.

Happy New Year.
