I would agree Turbojoe that two of those batteries will make a 4 lbs target very difficult to achieve as together they will weigh 26 oz (1.6 lbs). You would be up to 2 lbs just for the motors and...

Hi
Its wing span is 50" (1270 mm).
And being a biplane it takes up rather a lot of room.
A rather poor video of its second ever flight.
