Every module should at the very least have a full set of training missions so you at least have something to do once you've bought it. Training missions and a SP campaign are the least devs can give us (for all modules).
At the moment, even planes like F5 and Viggen are only somewhat fun in a game sense, unless you use them in MP or cobble together your own missions. This module has NOTHING going for it, except that it represents a plane that can take-off and land and make turns. You can do aerobatics by yourself but there's no feedback on your progress or skills. Doing fancy maneuveres on a PC isn't fun by itself, because there's no physical sensations (even in VR), so you need something else to make it more worthwhile, hence my suggestion that DCS gets a way to create and score aerobatics maneuveres. A system like this would be useful for all modules, because we can do aerobatics with most of the existing modules.
