Yeah, that is light. Mine came in at just a hair over 5 lbs. like 81 oz. as it came stock in the RTF package with the battery. It climbed at an excellent rate with plenty of power. I bought another 8 cell pack with 3600mah capacity to give more flight time. I go back and forth with lipos as I have installed an esc that will work with either. My only complaint is that when the motor dies you are totally finished flying and better be on the ground or set up and on final approach or your going down somewhere you may not want to. My other models kill the motor but you can bring it back on for say 20 seconds. Not this one. So keep that in mind.
