That looks great, kitnut! I really like the new fin & rudder, but it's nagging that I can't place it. Kinda reminds me of a Viscount tail.

Top notch work here!  8) No guess on the tail fin though  :-\

Thanks guys --

Well you're going to kick yourselves when you look at this pic, the tail came from this after I converted it from the Airfix Mk.32, back to a Mk.31 using the Magna Models conversion.  You get a number of direct replacement parts for the conversion so the whole original fin & rudder was spare.

Incidently, the Sunderland fin is practically the same height but a little broader at the top although it's not as broad at the bottom. And the Freighter's rudder is quite a bit broader at the bottom.

My initial plan to use B-24 landing gear has gone out the window --- they turned out either too small or too short for what I had in mind.  Previously I had shown what the main gear would be, now the nose gear has been solved.

I had decided to use the 1/48 Catalina u/c leg but what wheel to use with it caused some head scratching, I knew what look I wanted but couldn't find what to use.  Then while looking for something else in the stash, I found just the right wheel -- it comes from a 1/72 Blenheim (left over from my Bolingbroke Float Plane project).  It looks just about right when set next to one of the main wheels. 

Looks like most of the puzzle has about come together now, all I've got to do is figure out the tail (I'm going to remove the turret position altogether) and I'm also pondering moving the cockpit forward.  I'm going to put in a floor as the large cargo door I plan on will be displayed open, so you can see the water tanks in the cargo area.  I might go a bit berserk and detail some of the interior that would also be visible when looking in the cargo door.

For the tail area I'm going to use this Shackleton fuselage end, doing some part match-up, it looks like it will blend in without too much messing around.  It will involve some careful razor sawing as the join line will have to go about 2/3rd's along the tailplane chord

This pic is of the colour scheme and decals I'm going to use, I ordered them in 1/60 scale so they should fit about right.  I've actually bought two sets of this sheet, one in 1/72 scale too, because I'm going to convert my Airfix Catalina into the RW fire-bomber. I'v got one of 'Scott's Custom Resin Products' nose conversions to do it.  Scott is of Invader Hobbies out of Calgary.  The decals I'm using are from CanMilAir and Bill will do some custom printing as long as it has a Canadian bent to it.

I've been trying to figure out how the main u/c goes together and Greg was kind enough to scan the instructions he has of the kit which this set is a direct replacement for.

Well, I've found an error on the instruction sheet (top pic), it shows that the retraction cylinder is attached at the top of the main strut and to the bottom arm.  But it doesn't go together like that at all, the bottom of the retraction cylinder should go to the top arm.  The top arm even has the little tab included which the cylinder should attach too

I found a photo which confirms what it should be like.

Here's some pics of how the u/c goes together, I've temporary mounted it on a piece of card as it was easier to hold things together.  From here I'll work out the new wheel bays for the Sunderland, I will have to change the angle of the main strut as the fuselage sides are almost vertical and the gear is made to fit the rounded curve of a Catalina

Another thing I've just noticed is that the top arm should be wider at the hinge/fuselage connection, than the lower arm if the photo of the real thing is to go by.  The kit parts seems to have it the other way around for some reason

I was giving my Aircraft of the Fighting Powers books another read and in volume VII there's an entry for a Short Seaford.  This was a completely upgraded Sunderland and would have been designated a Sunderland IV.  It was powered by Hercules engines of 1800 hp. This falls perfectly into my scenario of Dart turbo-props of around that power rating.  It even has the dorsal fin fillet .  The civil version was called the Solent

There's a Solent in the 'Solent Sky Museum' at Southampton in UK, and it's open to walk around too!

If you look friendly enough they'll let you into the cockpit as well, It's a LONG way down from there!

Back a few posts I mentioned that I would ponder moving the cockpit forward so it wouldn't be inline with the propellers, the Short Seaford drawing shows me what I really should do.  That's move the whole forward fuselage  a scale 3'-6" (or there abouts).  There's a very important station which seems to be a production join line and it lines up with the front spar assembly where it goes through the fuselage. This station is also the one where the beaching gear is attached to as well.  What the Seaford drawing shows is there's a space between the the windows now which were equally spaced either side of this station on the Sunderland (between the third and forth window starting from the rear most window). So what I'm going to do is add a plug into this spot and do the same as what Short did.

The Seaford had an increased planing bottom too, 6'-0" longer apparently.  It had 3"-0 added in front of the step and 3'-0" behind it. The front extention would have been included with the forward fuselage stretch, but the rear extention is not so clear cut.  It looks like just the planing surface was moved back along the rear fuselage which is a bit more complicated to do.

I've just bought a book on the Martin Mars, it's a Coulson/Ginter collaboration, and in the text the company that originally got hold of the Mars flying boats had evaluated a number of different flying boats to use as fire bombers.  The Sunderland was one of them and what is really interesting to me, is what I calculated the Sunderland could carry as a water load, was pretty much what it was worked out to by this company, 2800 gals of water.  Of course, this being a half Seaford conversion now, with much more powerful engines (in real life and my alternative) I think we could stretch that to 4000 gal I think  ;D

Well, I'm in with this so I'll see where it goes from here -----

First thing to do is make up four new engine nacelles, new casting that is ---
