radd's is a good tool if you really have nothing else to consider, i self taught on a blade cp and was hovering a whole batt. pack in 3 days with the stock ni-hm. (at least 3 flights everyday though). i'm not bragging or anything, just to tell you it's possible, i've had it for less than 4 monthes and right now, i'm doing loops and rolls. i guess i do pick up new stuff faster than some other people, maybe it's because i'm only a kid still?
