First of all, it's a "profile" plane using the side view profile on a flat surface fuselage.

It looks like one of the varieties of "Sticks" out there. Since it has the huge elevator/rudder/ailerons, I would say that it was intended to be for 3D. It looks light enough for that, especially with your "prop hang" comment.

We say that nose heavy flys terrible where tail heavy flys once. If you were able to land it, then it may be teetering on being tail heavy, but the Center of Gravity is most likely right at the center point, meaning neither tail nor nose heavy.

If you want to get rid of that, shift the battery pack forward a bit and check it. You don't show the bottom so we don't know where the battery is on that model. But, move it forward slightly - say a half inch, then fly it and see if it "improves" to what you prefer. If not, shift it further and try it again until it is right. If you cannot shift it further forward, then add some lead weights to the front, as far forward as you can, say an ounce, and see if it helps it fly better. You can get sticky lead weights from your local hobby shop or via Tower Hobbies or other mail order sites.
