The blue vs the orange is a lable design change. All FASST receivers (and modules) have that design now = orange. If any blue ones, they are just slightly older stock.
Are you 100% shure booth of them where R603FS? Maybe one of them are R603FF?
I messured booth right now (R603FS with blue lable and R603FS with orange lable) - they booth weight 13.5 g right out of the box.
As for autodetect PPM/HRS -> all of them have that feature (and it has always been so) no matter what color the decal is -> R603FF & R603FS.
