While keeping an aircraft as light as possible is a good idea, it is not always possible. Even on real aircraft, we used to use 25lb lead filled "sandbags" to balance the cargo in helicopters.
A bumblebee isn't supposed to fly but does.
My plane is supposed to fly but doesn't.
Balances out doesn't it : )
