I've used orange receivers since last year with my JR 2.4 transmitter. I have them in an Evader, a StrykerQ, Phase 3 F-16s, a Stinger, a GP F-20, a Mini Ultra Stik, a Hobby Lobby F-35, a Demon pylon racer, and a motor glider. I use satellites on all. The StrykerQ has been over 1,000 feet (with permission of the tower, using an Eagle tree altimeter); the Evader is a rocket and I use two HXT900 servos in it ($2.49 each); my buddy flies a GP Edge 540 50". Collectively we estimate we have over 1,000 flights on our planes. This is not an exaggeration. We fly three times a week, about 8-10 flights a day, each of us. In 1,000 flights or more, we have had no documented issues proving the receivers were at fault in any crashes. I say they are bulletproof and would have no fear using them in anything. Do I have other planes and helis worth a lot of money? YES. Do I use them in those airframes? NO, mainly because those planes and helis were purchased before the orange receivers existed. Bottom line, buy one or two, and have no fear.
