Precision is a bit of a cheek though as they took some work to fit together until you get the hang of splitting the mdf tags in two to make them fit. Once this was done they were pretty easy o glue together. As I suspected the mdf "has a thirst" and I painted them by hand first with my trusty radiator paint with water to seal the panes on the sprues. This worked for the most but a few need another coat of spray before detailing.
Now I've had a play with the kits and future purchases will be more tailored to the projects at hand.
They will form settlements/labs etc for humans heading out into the great black unknown of the universe.
Most of the mini's for this are already bought.More than I originally planned ..... of cause I got carried away.
Now back to my VSF and its long list of jobs to finish.
