Maybe you are familiar with balsa wood

Maybe you are familiar with balsa wood if you are interested in making models or other artifact. But do you know how to choose the right grain of balsa wood to complete your project? If you are using the same type of balsa during the producing process, I'm afraid that the flexibility or stability of the model is not qualified.
A-grain is cut at tangents to the growth rings and that's why it is know as a tangent cut as well. This type of balsa wood is flexible and easy to deal with. However, its strength limits its use. It is not suitable to bear much pressure but it is able to be used make the items which need more flexibility, such as spars, fuselages and forming tubes.
On the contrary, C-grain is cut sliced off at a perpendicular angle to the growth rings. This type of balsa wood is strong and stiff enough to bear certain pressure. But the lack of flexibility makes it easy to break while being bent or carving. It can be used to make wing trailing edges, wing ribs, fuselage sides and fuselage formers.
B-grain is cut at a angle between A-grain and C-grain. This type of balsa wood is not suggest to be used if the project requires essential qualities. It can attain the features of A-grain while the other end attains the characteristics of C-grain, and that's why it is difficult to deal with.
