"It's from the mistakes that we learn"

That's one of my favourite quotes. Crashes can happen more often during the training process (you never stop learning, you just finish your training when you learned enough to fly on your own), but after that. they will continue to happen. Maybe once each 10 years, but they will happen. This leads to another quote. "You may afford to buy, but you must afford to lose". With my Edge was like that. 6 months of intensive 3D flying and no mishaps. Up until one day, I decided to fly on a low Rx battery (got overconfident). Last inputs: up elevator (slight) and full throttle. Plane looped to the ground. It was a pure stupid thing. After a while, crashes due to pilot error get more rare (not inexistant), because of increased skill over the time, but crashes due to equipament failure, are always there, no matter the pilot skill.
