1258 is low voltage and only has 166 oz/in torque at 6v which might work ok full voltage but your gonna notice a difference when your voltage starts to drop... in a bad way... and cant be used w a lipo wo a regulator. if you already have one it wouldnt hurt to try it out.

1256tg is the high torque version, 277 oz/in @ 6v which would work great and its about the same price, but if your using a lipo it will have to be regulated.

1268sg is high torque, high voltage w 347 oz/in @ 7.4v, 208 oz/in @ 6v. a bout $20 more but you wont have to regulate a lipo if your using one.

they even make a high torque, high voltage brushless version but its noticably more expensive...

@matt ... i see your from azusa, ever hit up rev?
