This is a beautiful plane, and there are a lot of small details in every part of it, so modeling this aircraft from photos was painstaking, and problematic. I wanted to be accurate and have it look right, and the small amount of information I found online was helpful, but only took me so far. Fortunately, working in the Avionics industry enabled me to go on board one that was sitting on a tarmac at an airshow. The details I was missing could be made up for by taking alot of closeup photos with my phone. Coupled with brochures and handouts from Gulfstream, I was able to put together a pretty accurate product. The end result I think, came out rather nice.
