I've recently built the 2009 starter kit edition (one of a few 'lockdown' builds!) and the moulding seems to have held up quite well. I didn't have any major issues with flash or short shot parts (both of which were major issues with the venerable Comet kit I also built). The Whirlwind is a kit I remember making years ago so thought it'd nice to build another. Mine's not up to the standard of builds on here but I'm happy with it so that's enough for me - I could spend years on a kit and still not get close to the quality of the builds you see on this forum (and others), however, I also suspect I'd lose my mind in the process!
