Having spent last weekend building and painting a towns worth of 28mm buildings I decided to take it easy and give the Zvezda 1/100 scale kits a try. I was interested in the BM-13 in particular as I had a great deal of difficulty with the Battlefront model that I had attempted. As noted earlier the Zvezda kit is a snap-together model and is very cleanly cast. I decided to start with the part that had given me the most trouble before, the launch-rails and elevation frame. This went together like a dream, despite being made of four tiny parts. The fit was perfect and the parts snapped cleanly into place (I glued them anyways).

be careful to push the frame tips all the way trough the launch-rails
the pins pop out the top and form the locators for the rockets
