well,i bought the 2200mah lipo for my hbfp but i`m still waiting for some other parts,since lama is the only heli in my fleet that flys right now i decided to stick the big batt. in it and see if it would take off,not only got up in the air but it hover for 20 min., i know its pointless but i guess i got nothing better to do till i get the other helis working
