We purchased a X47 Airsoft Rifle from Stunt Studios at Big 5. We brought the rifle home and weighed and tested it to see if it would work. We then carefully took the important pieces out (Firing mechanism, barrel and battery) and discarded with the rest of the plastic. Most of the plastic was heavy and only for show. This lightened up the load the servos will have to bear, allowing for a quicker response time on the servos. The only problem is we now lack structure for the gun as well as a loading mechanism, but these will be fixed with some metal pieces and a makeshift hopper using gravity as its acting force.
