First flight and I crashed.
This first flight experience is very common. Even if the plane is perfectly set-up before the flight, wind conditions and just the torque of the engine can make the model do unexpected things immediately after take off. The inexperienced pilot will over-react and mash the plane into the ground simply by not knowing how to correct for the conditions that are happening at lightning fast speed. It is highly recommended that new flyers get an instructor to take the plane off and get it up to altitude ("3-mistakes high") before the student pilot takes over the controls. The effort of learning (and rebuilding after your mistakes) is worth it. Good luck with your second attempt.
