okay, so i bought a swift mini from mscomposit the other day because being epp, i figured itd be a great plane to take out and fly pretty much any time, plus its smaller than my byp yak, which is a bear to fit in my car without it breaking.

so i built this thing, and put an eflite park 300 motor on it. they suggested an axi motor, but i didnt feel like paying 70 bucks for one.

so, onto the question: they suggest a 400-750mah 2 cell, and i bought a 450 thinking keeping the weight low would be a good thing. problem is, i cant get the plane to balance out, its too backheavy. i also havent hollowed the plane out to place my rx and speedo either. does balance matter much on flying wings?
