Ok, So how do you use them in your games?
Mostly as niche-application auxiliary spacecraft and additional shipborne firepower (Fighters only).
I find them too limited and cramped for much interplanetary travel -- for which big craft are much more comfortable -- as well as being overly-expensive given their comparative flimsiness in space combat.
Mine is CT B2, small-ship TU, and therefore small craft are very fancy and very costly ship's vehicles, for the most part. Also, there are a few pieces of close reading in CT that are relevant to MTU.
First, CT tells us that "most" small craft are unarmed and uncomputerized; I presume they primarily operate as interface craft between orbit and the surface, under the guns of the planetary defenses and/or their motherships.
Second, they appear to be intended for jaunts of up to 6 hours, but require additional accommodations for use beyond that window. This again suggests short-range applications. I am open to using them for intra-satellite travel within complex moon systems around GGs, but not so much toward using them for interplanetary hauls, except under emergency circumstances.
Last, there is a little-recognized small craft space combat system detailed under the small craft driver skill in CT/BT; the combat mechanic example there suggests that small craft, due to their simpler drive systems, are comparatively stealthy and can slip off of sensors surprisingly easily, throwing pursuers (even perhaps incoming missiles) off their tails at ranges big craft and starships would in comparison be easily-targetable at.
This particular feature makes small craft
ideal for daring getaways, blockade running, stealth insertions, smuggling drops, and all kinds of "flying by the seat of your pants" bush operations. Throw in a rough ride from the lack of big craft acceleration compensators (simpler drives, remember), and I can
always find an excuse to put PCs in a small craft for an action scene.
As mentioned, the other principal application IMTU is to provide CT warships with additional firepower in the form of supporting Fighter squadrons, but that scenario should be fairly self-explanatory.
I also find myself using them -- when they are reasonably available -- for boarding and inspection duties, either downport-based or mothership-based as fits the locale; this avoids hazarding the larger, higher-value asset, which can then stand guard, training its own guns on the docked vessels as necessary to deter -- or at least realistically complicate -- PC shenanigans.
