This is an aspect of modeling that I have come to enjoy nearly as much as actually building the model itself. As mentioned above the research starts right from the moment you decide which model you want to build. The first port of call is to make a choice of which kit you buy based on your required accuracy, and of course, how much you are prepared to pay for it. With the Space modelling market being quite a narrow field compared with other genres sometimes your choice is quite limited. One classic example I can quote is of the choice between a Revell & Airfix 1-144
th scale Saturn V. Without going into detail the Airfix, whilst it has its’ errors, is streets ahead of the Revell in terms of accuracy. If you are of a mind to go for a highly accurate representation of the real thing this is where some deeper digging about comes into play. One of the first go to places has got to be Mike Makowski’s website, Space in Miniature. Mike has written a series of booklets, and in his own words they are about “How to build accurate models of real spacecraft”. They are very reasonably priced, and contain an absolute wealth of invaluable information. If you are attempting big modifications, and or scratch building another vital resource is a series of drawings that are penned by David Weeks. These can be found for sale at RealSpace Models, the sets cover most of the major US manned space programs. I have singled out these two sources as they have become my two bedrocks, or as I like to call them a stable platform. Another highly important type of reference has got to be photographical evidence, and in this day and age we are fortunate that the internet abounds with images that can be used as references for your build.
