Not being able to see the layout of your landing gear mounting points makes it difficult for me to see how this layout will be and what stresses would be where ..the pods could be modded to mount out riggers into with the mains mounted in the fuselage..if the outriggers are mounted in the outer engines then the stresses would be passed thru the entire wing ..mounted in board would cause far to much stress from the inboard engine out to the wings tip..breakage big-time and a ton of wing flex which I hear isn't really helpful on landing 😀
If it aint broke ,,fix it until it is .
Over kill is often very understated .
I know the voices in my head ain't real but they do come up with some great ideas.
Theres few of lifes problems that can't be solved with the proper application of a high explosive projectile .

Quote from: PR19_Kit on April 06, 2023, 01:27:11 PMBefore taking a 'before and after' pic I took a good look at the OOB wing mouldings and was surprised to see that they're re-enforced on the inside. There are strips moulded into the inner surface of both upper and lower halves......


Very interesting. have never seen that amount of re-enforcing on a kit. Surely makes the tooling more expensive, but a nice touch.  I have had a few kits that could have used that.

It surprised me too Dave. Neither of the 1/72 scale B-52s I have, Monogram & AMT, have anything like that moulded in, and the M'gram B-36 has such thick styrene for the wings you could WALK on it!

You're right, it must cost a lot more to tool that up.

Maybe it decreases failure rate when removing from the moulds ?
Do not condemn the judgement of another because it differs from your own. You may both be wrong.

After a vertigo induced lack of mojo, I'm back on the B-54B again now, and about time too you might say.

I'm not sure if I'll actually get it all done by the end of the GB, but what the hell, I'll do it anyway.

Working on the tail section at the moment, with the Bear fin being mated to the B-29's rear fuselage, with the American tail turret being melded into the bottom of the rudder, and so far it's going OK. I'll 'Americanise' the shape of the fin-rudder I think, it's all too Soviet looking at the moment.

Pics later hopefully.

As promised here's the new tail of the B-54B. Needed some sheet packing pieces and will need LOADS of PSR no doubt, but I expected that.

A more tapered B-29 tail cone with a Tu-95 fin/rudder grafted on top, with the B-29 tail turret fiddled in place instead of the Tu-95 turret. It just shows how much Tupolev DIDN'T change the B-29 design.........

The front bit of the B-54B is a standard B-29 nose, but obviously I won't need the wing roots moulded into it as I'll have the coking great Tu-95 wings some miles feet aft. So I filed the B-29's wing roots away, and that left a socking great hole....... :(

Mucho cutting, filing and trimming of styrene later the hole is plugged, sort of. As with everything else in this build it'll need lots of PSR of course. :(

Presto!  :thumbsup: The same stuff that Dizzy uses a lot of.

If you can get it, but at the moment I can't.  :banghead:

Because this is meant to be a half-way house to the proposed B-55, I plan to hang the four turbo-props on pylons, as was intended for the XB-55 as well.

I can't find a single other design with turbo-props hung on nacelles like this, does anyone know of another one?

Here's the proposed XB-55.

The original Boeing Model 474.
The  XB-47D but they only have the inner engines replaced a single Wright YT49-W-1 turboprop.
The only aircraft that comes close was the modified MD-81 proposal for the Lockheed P-3 Orion replacement having a pair of propfanned engines back in 1988 known as the P-9D.



It might be worth trying the former USSR or Chinese aircraft design agencies for anything suitable.

The single B-47D was the only one I came up with too.

The aft-fan MD-81 doesn't really count as its engines were not wing mounted.

I think I'll have to scratchbuild my pylons for the B-54B as almost all the jet pylons I can find are too long.

You could put the propellers at the rear of the engines to save you a bit of time  :banghead:
