IMO there's no such thing as a "low powered" racquet. I can hit plenty of shots just as deep with my Prestige as I can with a Babo PD. I also hit plenty of shots way long with "low powered" players sticks.
IMO, the more important things, as already described, are technique and string choice.
I would also add that the string pattern perhaps has more to do with the equation than the stick itself. More open string patterns have a higher trajectory off the stringbed than dense patterns. therefore, it may be a tad easier to hit shots out of bounds with open string patterns, if one still has trouble with producing enough spin to compensate.
