Full size dimensions from [link]http://www.globalaircraft.org/planes/dassault_rafale.pl[/link]

Dimensions
Length: 50 ft 3 in (15.3 m)
Wingspan: 35 ft 9 in (10.9 m)
Height: 17 ft 6 in (5.34 m)

That gives a Length/Span ratio of 1.4037 to 1.4056 (depends on whether you use metric or imperial measurememts above)

From the Dassault web site

Dimensions
Span 10,80 m (33.5ft)
Wing area 45,70 m2 (491 sq ft)
Length 15,27 m (50.1ft)
Height 5,34 m (17,5ft)

That gives a Length/Span ratio of 1.4139 to 1.4955 (depends on whether you use metric or imperial measurememts above)

From the above I would take 1.41 as a best guess


From what you quote

bvm rafale specs
L 86"
S 64"

L/S=1.34375

wjm
L 95.5"
S 62"

L/S=1.54032


So it looks like neither are exctly correct, with BVM being 3" over span, and the WJM being 5.7" under span based upon their quoted lengths.

Not sure if the tip missiles are included in any of the above , so even more uncertainty.

It looks a nice model either way.
