greetings to all
i am making this cargo plane in left over 3mm depron  while making i made it big(with out any plan own design) now as it require big wing tried to join 2 39" kf airfoil wings  but not enough strength    so thought of making a bi plane using those 2 wings.
auw will be around 950-1100 grm thought of using twin motor
i ordered these motor http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=12916  , with these 3 blade 6x4.5 , will it be enough
any suggestion
thank you 

Since your AUW is gonna be 950-1100grm, go atleast for 300-350 watt motor..
