Not too bad really, but I made my first big mistake on the 4mm scale IBG Scammell Pioneer. I failed to see the spring hangers on the diagram and assumed they were part of the injection pops and chopped them off, leaving them on the sprue. (phew, I might have just trimmed them off and ditched them.) They are perfectly obvious on the diagram, but only if you PAY ATTENTION! I came up with a cunning plan, cut them off the sprue, lost one (deep joy) and glued them into the locating holes. All being well I can hopefully make a new one, then glue the springs to the hangers as they should be. This is a nice kit to build, I have had a minor incident with the rear drive train, but only my clumsiness really, and all is well. So I'm remaining confident so far…
