critterhunter,
each motor draws 390ma, so a total of .78A draw. not sure what the C rating of the fullriver 130mah cell is, but its obviously enough to power the plane. there's two new cells out, a 160mah and a 170mah, both weigh a gram more than the 130s and would probably give you a better duration. you can get both cells (the Plantraco 160mah and the DU 170) from here, http://www.bsdmicrorc.com/products.cfm?catID=10001

bsdmicrorc.com also carries motors that you could use for replacements, 6ohm - 10ohm 6mm motors would work. i've yet to see any other counter rotating props for 6mm motors, but you could use the blue Aero-X prop as a replacement as well.
