Keep your wings level
Tip for beginners:
The question is NOT whether you will crash-land or not, but WHEN. And when you do so, remember this advice: KEEP YOUR WINGS LEVEL.
The reason is simple: if you hit the ground with the tip of the wing first, you will probably destroy the wing or damage it badly. You will then hit the ground with the nose, then the other wing then the tail, then start over. In other words, you will do cartwheels with the plane and induce much more damage to it than if you hit the gound with the bottom of the fuse or even the nose. I dove my trainer nose down BADLY and sustained no damage to the wings (the alluminum bar bent but no big deal). Oh, and by the way, do not epoxy your wing halves, some tape to keep them together is fine.
Remember, KEEP YOUR WINGS LEVEL
