Is the Rx Rebooting problem unique to Spektrum radios? Or is this something that I need to worry about with the Futaba system that I will have in a few weeks. (The wife is holding it till Christmas, But that's Okay, I'm holding her new laptop too.)
It's specific to Spektrum/JR radios. The Futaba and Airtronics radios do not suffer from this problem. I don't know the figure for the Futaba equipment, but I know that the threshold voltage for Airtronics receivers is below 2 volts. So the servos will stop working long before the receiver does.
Now in Spektrum/Jr's defence. They have addressed the issue with low voltage reboot. One major step is to rewrite the software for the receiver so that the reboot time is reduced from 3-4 seconds so that it's now down below 1 second. So if a reboot does occur it's likely you will get control back in time to save the plane. But the easiest way to avoid this is simply to put a large enough battery in to avoid this even happening. I use 2500 Mah 4 cell packs with my JR 2.4 radio and have never had any issues with it.
