I suppose if I did go to 2.4 I would get the Airtronics rds8000, it's way cheaper than any of the others and I've learned from RC KEN that it will only reboot when the voltage gets down to 1.8 volts, so pretty much the servos will stop moving before the receiver goes into failsafe for low voltage. But what manufactures need to do is have a real time reporting of RX battery voltage on your TX, if we can make these thing hop frequencies, why can't we make them tell us critical details to the transmitter, like receiver input voltage? Ya listening manufactures?!
