Well, I guess you could look at it this way... you've already got your first crash out of the way! Now, go fly and enjoy it!! Seriously though, It doesnt matter how much you prepare, sooner or later, it's going to happen, that's just the nature of this hobby. Whether it be a battery pack, engine, Rx, or servo failure, or maybe the R/C gods just simply dont like the color of your plane on that particular day, and decide to throw it to the ground... crashes are going to happen. Just get in the mindset that you will make thorough preflight checks, keep your plane and equipment in good working order, and go have fun. Dont waste all your time worrying and wondering if you quadruple checked every inch of the plane. This hobby is supposed to be fun, not worrysome!!
