Any system is only as good as it's weakest link. If you are flying just a F450 with no other gear I'd trust the orangeRx. I plan on flying with a GoPro Hero 2, FPV Gear, $10/each graupner props, and a $500 gimbal.... I will only fly with TRUSTED name brand tx/rx with proven failsafe systems. Honestly the orange receivers are an amazing deal, I just couldn't live with myself if $2,000 flew away because of a brown out and it's happened to people before. Someone over at RCG talking about a total loss fly away with their Turnigy 9X and while that's an AMAZING deal for a pretty functional transmitter, it doesn't have the same Quality/quality control as the bigger names. I decided to pony up for a Futaba 8FGS and love it. It doesn't guarantee no fly aways but it gives me good piece of mind.
