Very nice review, Michal, and thank you for the kind words about my earlier review.
While not perfect, the series really gives a depth to the most-famous air campaign of the war. And given both the overwhelming popularity of Luftwaffe aircraft and the dearth of good RAF BoB planes in the largest scale, it's not surprising that Kagero has concentrated on those planes. There is also the issue of how regular most of the camo schemes are for the RAF, so that once you've done a Type A and a Type B, well, you've done them all.
If Tamiya would retool its excellent 1/32nd Spitfires down to a Mk. I/II, it would do a lot, I think, to spur more RAF decal makers. Just one man's opinion.
Besides, who can resist a plane with "Beware! Beginner!" on the side???
