I recently heard of them when browsing for some IPs. Imagine my surprise when I saw they had a 1/32 correct IP for the Special Hobby Fiat G.50! For those who may recall my build on that, (the WIP is one here somewhere), I had to scratchbuild a 2 piece representation. The G.50 IP was unique in that it was an upper and lower panel, separated by a curved support strut that ran the width of the cockpit, in front of the pilot. SH only supplied a generic flat IP.
Now that I've seen the quality, and in 1/72 no less, I will certainly be looking into Yahu for my next build!
