RE: Is this a good plane for 3d?
3D? No, not a good plane.
To get your sticks going with airplanes and learning how to land a plane, yea it will work. You can do all the roller moves and most advanced aerobatic tricks.
If you can hover it, your doing great. It will wing rock like crazy in a harrier and may even snap out. The slow flying of that bird is why it does not make a good 3D plane.
For 250, hard to pass up.
Buy it.
