You never know when one will go in. I treat every flight like the last, emotionally. Be prepared. I see a lot of guys gets angry and down right mad when they go in. Sure, it is no fun, but it is part of the gig. Gonna fly 'em, gonna crash 'em. It's just a matter of time. All you can do is ensure proper maintenance techniques and proper set-up. The rest is up to the RC Gods....they get hungry often. Besides, what else would I do with my time and money
