Bests & Worsts Reviews from Amazon

I have both the S107 and S107G. After reading about the similarities, I thought I would outline the differences. The primary difference seems to be a change of software. The S107 had an issue where when turning and moving the throttle far up and down, the helicopter would spin very rapidly. This would cause it to be a bit out of control, but was kind of fun if you learned to work with it. the S107G has fixed this issue. While turning, the turn speed is almost completely unaffected by throttling up/down. The USB charging cable has been slightly improved in the S107G. With the S107, it would glow dim red while charging, and bright red when done. On the S107G, it is completely off while charging, and glows when done. Finally, you've got more color choices on the S107G. I hope this clears up some confusion.
