I decided to make a brave step and try to scratchbuilt wings inflattable seals:

I removed the stock Revell ones and glued on top of them two pieces of thin sheet styrene (...you must have been knowing me by now: they are cut pieces from my sons' bon bon chocolate ice cream mini trays...).

They are placed in such a way that a wing fillet can be inserted into the device, much like the real thing (a bit simplified, of course)

After the required trimming, they were glued in place. After curing, the wings are going to be inserted into place, to see how the area will look.

Cheers to this Great GB and those Great Followers!

This is a really big kit, Spiros (@fiveten). Perhaps you can use it for a coffee table when you are done. I have a 1/48 scale Tornado IDS in my stash, and I thought it was big. Something this size will really need all of the internal reinforcement!

And a gluing update:

After a supplementary reinforcement at the wing roots, I attached the air intakes...

...and the aft AB cover that contains the thrust reversers.

As you can see, fit leaves a lot to be desired, but my Excel blade, 220 grit sandpaper, possibly my bastard file, liquefied styrene and finally the magic Squadron Green will do the trick!

I also started to take care of those wing/fuselage gaps, that have to be minimal at the areas of "swinging".

Chers frmo a happy moldler! (misspelling due to all that glue sniffing...-LOL)

I have definitely contributed to the bad fit, my friend @airbum.

Also, it is not uncommon to see a "modern jet" kit with fit issues. It is not so easy for the kit manufacturers to design all those complex shape parts and achieve a perfect fit.

Squared fuselages split in front/back AND left/right, variable wings, to name a few, cannot always be molded to fit perfectly.

1/32 parts being bigger, can amplify the problem and some builds may be discouraging for some modelers.

Having said all that, a detailed modern 1/32 Tornado, with THAT A3 size super decal sheet, at a price of 45 Euros, can tempt a few, yours truly included, to tackle the fit issues and (try to) build a very imposing model!

Looking good, Spiros (@fiveten). I suspect that portion of the fuselage where the wing would fold into is larger because it would need to be big enough to accept the thicker part of the wing if it were to fold back into the high speed position. I am sure that this is just something made necessary by the molding process, but it will be tough to fix. You are making a lot of headway and it is looking great.

Update!
Had QC/2 evaluation: found all this sanding work "interesting"...(Luckilly, only one minor test flight took place...)

Here's how the Tornado looks after a significant coarse sanding:

The vertical stabilizer is to be glued next.
Just for comparison, I placed an already started 1/32 Su-27 by the Tornado:...

The 1/32 Su-27 is awaiting a GB announcement, who knows when, to reveal its glory!

Gluing/filling/sanding oblivion!

After adding sufficient weight, I glued the nose.
Also attached the refueling probe.

Liquefied styrene added to the spine/fin base.
Of course, filling and sandind is on, hopefully to be finished soon.

Whew - man - I'm exhausted reading through all the gap filing, sanding, etc! This is wearing me out - can't imagine what you're going through - at 1/32! Coming along though... (and that's what counts!).
