Problem is, if he makes that kind of mistake, (more than once) better technology is not a substitue for good practice and/or good sense. People who depend on technology to keep them from brain farting will inevitably do it again........just on something else that matters. He is just lucky all he destroyed was his own stuff! This could have EASILY been a life-changing brain fart if his 50cc aircraft had destroyed someone else's property or, heaven forbid, physically injured or killed someone. He WAS LUCKY and should consider himself as such as he only harmed his own pocketbook. It doesn't really matter if you are flying 72mhz or 2.4ghz, there are still minimum checks that should be performed before every flight to keep the likelyhood of catastrophe as low as possible. At a minimum, your buddy should re-evaluate his pre-flight procedure..........regardless of what type of equipment he is using. By the way, if his brain fart had tuned out for the worst (and it easily could have) he could have cost you guys your flying site! In this litigious-happy society, that would have been a distinct possibility. I didn't mean to rain on anyone's parade but a dose of "WHAT IF" reality is in order here.
