i see your reasoning, but my flying friend has 2 of them, and i have held them, and watched him work on them, and they are balsa! these words came from his mouth about 4 thursdays ago "this plane is made from balsa, wich is more durable thatn u would think" i will check again today, becasue i am going to his house to convert the white pos clips, to dean plugs.
i will give u an update soon!
