North American Supermarine Sapphire Sabre

(1/14) > >>

Okay, well for this GB I shall be butcherrrr.... creatively modifying these two:

It's from the same background as my RN-buys-American builds. The idea is that Supermarine get told to build straight-copy F-86s as a panic measure for Korea, then afterwards they produce a more 'Britishised' version with an AS Sapphire engine and their own wing design that serves into the early 1960s.

Captain Canada:
This will be totally awesome ! I really like the Sabre, and the big, powerful look of the Fury, so adding even more power to it ?
#winning lol


That's promising. This combo has my attention.  :thumbsup:

It's not actually more power: the Fury had the J-65 which was a licence-produced Sapphire anyway. The reason I'm going down this route rather than the Aussie-style Avon-Sabre is that it's a damn sight easier to get the Fury kit than the one-and-only-and-rather-rough Avon Sabre conversion, which when you're done with it looks just like a regular Sabre anyway, unless you've got one of the latter to stand next to it for comparison....

And we're off....

Swift wings pruned from their centre-section, and we're immediately into problem no.1 (which was anticipated), namely that the Swift wing has a greater chord than the Fury one. Comparing the two, it's clear that the easy solution, having the leading edge of the root in the same place, puts the centre of pressure too far back since the Swift wing has greater sweep, so we have to go for the harder solution, which is to extend the Fury's wing slots further forwards.

Then problem no.2 (which was anticipated in nature but not in degree) manifests itself: the Swift wing is also WAY thicker. Keeping the existing wing slots and putting a big blob of filler on the bottom of the fuselage seems neither pretty nor credible (why would they design it like that?) so the only solution is to deepen the wing slots over their whole length... :o

I'm not usually a fan of power-tools for plastic modelling (they're only 1% of a speed setting away from melting, rather than cutting), but in this case, the Dremel came out, with a barrel-shaped router bit. Even on the lowest setting it still managed to blow through the bottom of the slot in places, but the job's still a good'un (well on the one side that I've done at least...)

Here's the slots. Top one just extended forwards, bottom one deepened along it's length:
