The starter squads are a Specialist Squad. Anything up to four models can go in this type of squad regardless of role (so you could put four aircraft in it for example). A model with the SA: Specialist must always go in a Specialist Squad.
Hi Charles,
No progress on having printed cards yet. The rules update is a pdf supplement to the rule book. It will tweak a few things, add some clarifications and add some new rules to try out.
