My newest mod..I call it the fast forward mod.I got tired of pushing down the left stick to sprint especially when shankin fools on MW2 :twisted: Pretty simple mod...a micro switch, one wire and two switching diodes(radio shack 276-1122).The diodes have to be soldered with the black stripe going towards (M) or right trigger on your VIKING chip.It turns on with rapid fire so you need the switch if you want to have rapid fire on and fast forward off.When your done you'll be able to sprint automatically!It was a pretty fun easy mod I hope you like it. http://i989.photobucket.com/albums/af13 ... c-Copy.jpg In the pic there should be one more switching diode in line with the first one...Took the pic before I figured that out!
