I've had very good luck with Berg's. I've got the 7 channel and (2) MicrosSamp 4L 4 channel receivers. You can program them to a failsafe mode even if you fly AM or FM so they emulate PCM's in failsafe. I fly them with Hitec HS-55 and HS-81 servos. I've flown the 7 ch in a powered glider style to over 1000' altitude and it had no reception issues with a Futaba 7C transmitter.
