Hello Chaps,
I finally got my Spitfire completed in between packing boxes to move to our new home this coming weekend! My next build won't happen until we're fully settled and my hobby area has been fully set up, so I'm guessing towards the end of May.
Anyway, I built this kit straight from the box (OOB), as I always do, to determine a VFM- "Value For Money" factor in order to perhaps help other modelers thinking about buying this kit decide whether it is worthy of any investment.
During the build, I did encounter two issues:
1) The wing root to fuselage joint areas had gaps that needed some filler and smoothing down with lost panel lines having to be re-scribed after the sanding. A easy fix to remedy. It would be easy for some modelers to push the wing-tips upwards to close the gaps tight during the cementing stage, but the dihedral would be incorrect with a much larger angle created, producing a somewhat flaccid "V" shape when viewed from the front.
2) The rear upper cowling that incorporates the front end of the cockpit, onto which the gun-sight is mounted, has a larger profile geometry than that of the front upper cowling to which it mates. It therefore stands proud by about 0.5 to 0.75mm and requires smoothing down and blending to the front cowling. Again, lost panel lines from this process require re-scribing.
I'm surprised by the two issues with the knowledge that this kit was new tooling in 2014, which means Airfix have had two years to address the molds to correct them. Maybe they have been corrected and the kit I purchased was one from an earlier run in 2014. But, that said, surely a manufacturing company would check the fits of their products prior to releasing them on the market, and if they did check, are we to assume Airfix let the issues go, to satisfy the pressure from their Sales and Marketing division to meet the release date deadline promised to their customers/suppliers of these kits to us, the consumers?
Apart from the above two issues, everything else went together great. The decals are excellent, as I have always found with the more recent Airifx kits, and look painted on when applied to a gloss clear coat surface.
The molded product was clean, crisp and without warp, sink and ejector pin stress marks or witness marks on seen surfaces. Flash was zero if next to nothing, but expected from a new tooling. The panel lines are nicely recessed- not too deep or wide as can be seen on some of the Airfix kits, these are a definite improvement.
The kit comes with two options of colors and markings, which are outlined in my WIP kit review and updates. I chose to go with the first option, that of a Royal Canadian Air Force squadron used in Malta during "Operation Spotter", which has a Sea Grey and Dark Earth camouflage color, the Sea Grey being painted over the Stone color of the typical two-brown Tropical camo pattern. The Sea Grey has a bluish-green tint to it which is called out as Humbrol 27. I mixed a couple of Tamiya paints to get a shade that I liked the look of; XF-54 Dark Sea Grey with a few drops of XF-50 Field Blue, then added white to tone it down in an attempt to give the aircraft a bleached appearance of which I imagine aircraft would have had after weeks of sitting in the hot Mediterranean sun on the Island of Malta and from the salt air and sand erosion.
Because of the two options of markings, there are different options of canopy, air filters, oil coolers and radiators- the Maltese version having a deeper "Vokes" air filter, oil cooler and radiator. It also includes a extra long range fuel (slipper) tank that fits to the underside of the fuselage and wraps around the "Vokes" air filter. I chose to leave this off because my boy is staying local around the Island of Malta and he prefers his bird to be more streamlined and more maneuverable without the hindrance of extra cargo.
The kit also includes bombs, which are not required for either of the two versions on offer, but could be utilized if after-market decals are purchased to represent Mk.Vb's that were used as fighter-bombers and dive-bombers, roles to which they were not well suited.
The cockpit is nicely detailed and would be furthered enhanced with the addition of after-market seat-belts.
There are no separate flap components with this kit, as there are with other Airfix Spitfires, they are molded solid, so no dropping the flaps down to produce some extra interest. The ailerons are also molded solid, bit the elevators and rudder are separate components.
The undercarriage can be modeled up or down, and at first glance, one feels that the design of the location areas for fitting into the wheel wells isn't particularly solid. The end of the oleo struts has a step that locates onto a step inside the wheel well. It doesn't look positive enough and also seems not to provide enough surface area for cementing. But, that said, when it came to gluing them together, I used a spot of CA glue on each of the opposing step joints, held the wheels in place for 30 seconds whilst visually checking that the angles of location looked good, and, hey presto, I was surprised that they were solid once set. Meanwhile, the rear wheel is a nice push fit into the tail of the plane and required no glue.
The assembly, painting and decal instruction booklet is very clear, concise and easily understandable, using nice 3D CAD images for the assembly instructions and color illustrations for the painting and decaling guides.
This kit costs $21.53 in the USA- that's about 15.00 pounds at today's exchange rate, and, it presently costs 18.99 pounds from Hannants in the UK. Therefore, it's around 4.00 pounds cheaper in the USA. Is it VFM- "Value For Money"....I'd say that it was reasonable, not excellent VFM, based on the fact that for exactly $2.00 more, I can buy a Revell of Germany 1/32 Supermarine Spitfire Mk.IIa that offers a lot more volume/weight of molded product and is a nice larger kit that goes together without issues...I know, I built one! 
Would I recommend this kit: Yes, apart from the two issues and it's price not offering great value, it is a great representation of a Mk.Vb Spitfire, probably considered one of the best and most loved versions of this iconic aircraft and I had fun building it.
My personal opinion regarding a score out of 10: I would give this kit 8 out of 10, based on the above.
Okay, enough of the rambling and lets get down to sharing my attempt at modeling this aircraft, but first, I apologize for all the photos, I was experimenting with three background colors, white, bIack and blue and I couldn't decide which I preferred. I hope you like!
Well, there she is my last build until my next build which will be a huge project- the Airfix 1/24 Hawker Typhoon Mk.1b!

Thanks in advance for your comments on this posting, for those that have followed this build and for watching the video, it is greatly appreciated!
Have fun and happy modeling!
Cheers
