I built this kit as a teenager most of 55 years ago. The kit is essentially the same, but now they’re laser cut. In the past, the panels were die-cut, sometimes you get one done with a dull cutter. That took a lot of extra time, carefully re-scoring everything with a narrow Exacto blade so the pieces wouldn’t split. This kit is so crisp, it’s a joy to assemble. It’s fun seeing old reflexes come to life while assembling this baby. I only have the FW-190 from those years, but also built this one (the Hellcat), the Spitfire, Me-109, and the P-40. Good times!
