This is a dedicated build thread for my Airfix Sunderland/Seaforth evolution into the Short Sudbury.
Sudbury is a small market town in the English county of Suffolk. It is located on the River Stour near the Essex border, and is 60 miles (97 km) north-east of London.
Sudbury is also a city in Ontario known for it's nickel production that is a result of a massive meteor impact. Also known as the big Nickle.
Shackleton Griffons fit mostly perfectly in place of the Pegasus's. I cut back the Griffon to just behind the engine proper.
And I bought a set of hollow punches a while back which can now be used to create covers for the way-too-many windows design. 7/32nds plus a slight window enlargement via Xacto blade.
Self defence will be upgraded with turrets from either a B-17 or Lancaster.
Weapons loadout is TBD but am thinking Tiny Tim rockets and maybe the ASM-N-2 Bat. And radar too. Bombs are so 1938.

I think I will use the larger tail as used on the Seaford. A Boeing 377 tail and stabilizers look to be good replacements.

This is going to be good! :D

looks interesting

You had me at contra rotating :o
-
Looks very plausable, love it.
-
That's a brilliant concept and I applaud your creativity, Mr Gimper!
More power is always good.

Loving it so far. My late father was a Sunderland pilot, so make him proud!

Yeah, about that...
Not sure how much work you want to do, or what kind of back story you're going to write, but here's a little info on the Sunderland, and why that arrangement could lead to some... 'interesting' times.
The prototype Sunderland MkI, K4774, had straight wings. Flew nicely. Then someone decided to add a stinger in the tail; a 4 gun Frazer-Nash turret. The weight of that shifted the C of G rearward, and the solution to that problem was to sweep back the wing leading edge to 4°, and it worked, but engine mounts remained in place, so that they were all now pointing 4° outwards. This introduced a quirk that new pilots had to used to. When there was a sudden reduction on the throttles, the nose of the aircraft momentarily pitched UP, rather than the customary down. Gentle use of the throttle was therefore needed on take-off and landing to prevent the possibility of contacting the water and 'porpoising'. With the added power of turbo-prop engines, that may be of greater concern.
Most people wouldn't know that, so you can probably ignore it. But I'm sure my dad would smile a bit! ;)

Worthy project with good start. Shackleton Griffon contra-prop power is way too get Sudbury moving. Progress to report ?

Not very hard to rectify though

Nice! Looking good :smiley:

Concur that's a very clean wing mod indeed!

Being as how I was bought up in sudbury and even now only live 15 mins away I'm going to be watching this.

Nuts! My plan to procrastination on this project until 2030 is exposed. Once the weather is better I'll get cracking on it.
@Dave: Thanks for the history on the swept wings.

interesting flying boat alternate version !
