The BioCom vult is easy to get (+400 to +450 standing) which shouldn't make the ship all that much better than other vultures. But, when it's almost exactly like the vult 4 (just more drain on boost) then no one's going to use it.

The BioCom vult should be just a little better than the Vult 4. Maybe make it have less drain, 200-300kg less mass, or 100-200 more hp compared to the Vulture MkIV. Then people will want to use the Biocom Vulture. As it is now, there's no reason to use it. But, it doesn't have to be as good as the Serco or Corvus vult.

Plus, with the new trade guild missions, make it accessible at +750 or higher.

But when considering changes, I think that the varients from companies such as BioCom, should have only 1 major difference than other ships, making it more interesting and encourage a more diverse use of the ships.
Such as: the Corvus has the fastest vult, the Serco Vult has the most hp, and maybe BioCom with the lightest vult. In my humble opinion

Personally, I think the Serco Vult needs a bit more push to live up to its drain, its mostly an unpleasant experience right now, and I'd rather take a vult IV or III if I'm supposed to go anywhere.

Corvus vulturis is an interesting beast. Haven't seen anyone use it in a while. :)

Agree with the BioCom vulture too, it needs an edge at some point, just a bit to make it "special" . Overall, BioCom is at disadvantage, only two stations, deep inside UIT space, and nowhere near real "action" .

5 more drain and 2 less cargo than the MKIV... 10m/s more turbo 10 more drain, , 300 more hull, 100kg lighter, and 3 less cargo than the MKIII.
