I’ve subscribed since it started and its a good mag. The last few issues they have started to include steam engines but the earlier ones were all IC
Where there has been an error on a drawing they have e-mailed pdf files of any revisions to all subscribers within a couple of days, not that there are many errors in their drawings. They will also e-mail when the mag is sent out so you know when its due as in the past publication dates were a bit elastic but that seems sorted now
