I know I'm gonna get flamed for this comment, but either you guys have:
A. invented super-hi-caps that hold 1000 rounds and only have to be wound once.
B. The RoF is like 5rps on a G4 hooked to a 11.1v
or C. That vid is BS from 1:40 on.
Sounds a heckuva a lot like a looped sound clip to me, and last I checked, hi caps can't fire 1000+ rounds without winding.
Also, running a gun on a 11.1v 10c battery is the same as running it on a 7.4v 20c... Which my TM can run... P.S.: I'm not bashing on G4s, they seem to be quite a deal if you like tons of externals, I'm bashing on the fact that it appears as if GI is lying to get more sales, and when kids take their beautiful new G4s and run them on 11.1v 25c LiPos, they'll find out that, hey, maybe stock guns CAN'T run on them for long.
