This one has always caught my eye.  After a bit of research, I found out that this is a slighty larger clone (kinda) of the Canaroc Starfighter Scorpion.  I got this one from Ebay pretty cheap. Once built, I plan on buying some replacement decals to make it look like the original. Excelsior hobbies has these decals available.

Notice the similarities, the obvious differences are the tube length and the wingspan. The SS has a main tube of BT-50, and a BT-60 for the engine housing, whereas the GW has a BT-56 main tube, and a BT-80 for the engine housing. The SS came with some small vacuformed parts. The orientation of the nacelles are also twisted 180 degrees.
