I have been looking around RCU, E-BAY, and many hobby shops on and offline and there seems to be a dozen different Dragongflys. Most of them look (in pics) to be the same, but then again in pics all micros look alot alike. I know there is the GWS, but there are other generic brand copies. Are all of them litteraly just design copies of the GWS or not? I would like to know because there are many upgrades for the DF and I would like to be able to use them. Please let me know of any differences you might know of if any.
