I find myself buying the new Airfix military aircraft when they appear in my LMS, but they tend not to get built as quickly.
So, my latest 'acquire and builds' have been the Seaking helicopter in both the recent new mold and the older kit issued with an additional fret allowing recent RN aircraft to be built. However, the 'older' kit has been the one which I've progressed more with and I am going to finish it in the markings of the Apollo recovery bird 'no 66' having acquired decals from a specialist supplier.
The new kit is unquestionably better, but I have progressed faster with the inaccurate, raised rivett, poorly fitting cockpit glazing version than the very high quality new mould. The challenges presented by each kit are different and complementary to my skill set, with the older kit allowing me to develop new skills and the newer one to apply the skills I have.
OK, the older Airfix kit isn't the best to use for the Apollo chopper ('66' being used upto Apollo 13), but some work with a razor saw and filler for the holes and gaps results in a model that has nostalgic value to me!
