As promised, the first photos.  I have a solid idea of where I'm going, just not translating it from thought to physical construction as quickly as I'd like.  Enjoy.

Obligatory box photo of the base/donor kit:


Card stock mock up of the hull:


The center box will be the crew cabin.

Photo showing the problem with the kit's inflation skirt size for 1/35 scale:


Edited to Add

I think the mock-up is done and we can move to cutting styrene.

Did a little more planning/card stock work today.  Now, I think I'm ready to start transferring this to plastic.

Now that, Mr Jello, is some very intense, serious engineering indeed.

I never thought about mocking things up with index cards or paper before. Will add it to the knowledge base. Seems very useful.

Thanks for the update and the great tip!

You know -- you might not have to do anything to the skirts. This was something back in the day ---

I remember seeing something about British hovercraft on TV, there was all sorts of types ranging from small personal types (even racing ones) to the huge ones

I agree - look at the Kaiman-10 picture - the skirt looks about the same. The mockup looks good. I say go for it - full speed ahead.

Proportionally the lightweight Kaiman-10 skirt is much deeper, almost half the machine depth
when inflated, than the 1/144 LCAC skirt.

The RNLI hovercraft in the photo is also a low weight machine, and the skirt depth is still
about a third of total depth, an armed/armoured craft will be quite a bit heavier which will
effect the skirt depth.

Physics is physics.

You guys doing super job on research and ideas.
Those photos provide insight on skirt height.  Be a sweet range (probably narrow) where skirt size works for kitbash. 
Interesting challenge.  Sure you will do well.

Progress report:

Engines mocked up:

(more detail has been added since this photo was taken)

Look at all that white styrene:




Got to cut some windows and start on the crew cabin.

Now that's a boss looking power-plant if ever I saw one, Mr Jello!

Thanks for the report and the good news that this is proceeding apace.

That's looking good! Do you have a 1/35 figure to visualize the size?

Super scratch work with card stock.  Beats mine.  :smiley:
Agree - 1/35 figure would be helpful.

This build takes my attention, LJ I am always excited in seeing hi level scratchbuilding !
THe preparatory cardboard mock up is a great idea, I never thought to do so...

I've been futzing with ways to increase the skirt height, photos later.
