I sort of agree with DR-1 Driver. My feelings on crashing are: if you haven't crashed, 1-You've never flown --or-- 2- It's just not your turn yet. You can prepare and prepare, do the Santa Claus thing (make your list and check it twice) and fret over every detail, and random chance will still come along and slap you silly the moment your back is turned. Small things become big problems, such as that servo or battery connection that "doesn't feel right" when you push the connectors together, or the clunk you didn't know has broken off the end of the line inside the tank, etc.

Don't beat yourself up too bad, just do a thorough preflight before each start-up, and take good care of your equipment, including a good preventive maintenance program on batteries, hinges, tanks, anything that is prone to fail with continuous use.

Then just go out and have a ball.
