It may be worth mentioning the tank kits that a beginner may do well to avoid, I would suggest the original Tiger and Panther. The road wheel assemblies on both these kits are a bit confusing, and the Panthers individual suspension arms definitely do not help. I can remember many years ago my cousin, who was about ten at the time, slinging a part completed Tiger across the room because he couldn't make sense of the wheels. I had a lot of difficulties myself at the same age. Ironically, I did suggest a year or two ago that Airfix re-release some older kits for beginners to try because the new stuff can be quite complicated. The Panther and Tiger are good kits, I've made a couple of each over the years, but are probably best left to modellers with a bit of experience.
