For a warmup, I did a couple of open top speeders which are pretty Star Wars standard. Tankerenians are weird, they like fast vehicles, so these would only be found in cities and towns. They are small enough to fit inside a cargo transport so they are everywhere as a secondary mode of transport.
What they really like are their skyspeeders, something like a cross between a cloud car and a snow speeder. They are insanely fast for 7 or more person vehicle.
The Tankerenians only developed a vague sense of warfare and they do have some horribly antiquated fighters. They are limited to in atmosphere flight and are totally outclassed by even the oldest Republic designs.
