The SGU shuttle is a small cargo ship inspired by the Destiny shuttle  as seen on the TV series Star Gate Universe. This representation is really only approximate as I didn't have very good reference materials to work from. It features both FTL and Warp drive but I prefer the Warp drive as it is easier to manage in my opinion.
The cargo capacity is 2 of the standard 1.3x1.3x1.3 meter cargo containers used by Dan's UCGO add-on.
In addition to the UCGO compatibility it has minimal UMMU support in that it can carry 4 UMMU astronauts.
Have fun**Update**
Fully compatible with the RTF city ship available at the RTF site
