This is still my go to gun. Its been upgraded further to a SHS 16:1 gearset, and a WASP FCS bluetooth fire control system. Improved trigger to get rid of that loooong trigger pull. Plus quite a bit of battle scars to that slick paintjob. Shoots at 390fps with 0.25s. It does have a quik spring change but I rarely swap it. Spring change is faster than an AUG since there is no screws involved. The biggest battery I can fit in it is a Turnigy nanotech 25/50C 2200maH 2S. Sometimes I run a Turnigy 35/70C 1500maH 3S.
