Hi Teacup,
Actually the problem is the square versus the cube rule. Take a cube, 1cm on all sides and weighing 1 gm. Now make it two cm on all sides. Now the volume and mass of the cube has gone from one gram to eight. The same applies to dragons.
But the strength of a muscle isn't based on its cubic volume. Muscles work by sliding fibrils over one another, and the strength of a muscle is related to how many muscle fibres there are. The number depends on the cross sectional area of the muscle. So now say our muscle is one cm high and one wide and one long. It has strength x. Now increase the volume of the muscle again the same way so that it's two by two by two. The strength has only increased by the double of the height and the width. Therefore the muscle weighs eight times as much but only has four times the strength.
This is why small creatures are always proportionally stronger than large ones. It's why insects can't grow beyond a certain size - their muscles need to increase enormously in size to power them and an exoskeleton doesn't give them the room for that. It's why if you look at weight classes of weight lifters the smaller classes always can lift more in proportion to their weight than the larger classes.
If you want a dragon to fly, you need magic or a major redesign of its body to give it's muscles better purchase and gearing, and maybe deferent biochemistry as well.
Cheers, Greg.
