Spektrum still has an issue with brownouts that other brands don't. Yes it's true that any 2.4ghz receiver will reboot if the voltages gets low enough, but the threshold is set lower on all the other brands. Spektrum reboots at 4 volts,
Eh, it's less than 3.2 volts not 4.
Equipment, particularly servos can produce momentary large drains that make it appear that the RX is rebooting at higher voltages, but what occurs is that the voltage drops too quickly for a lot of meters to register correctly.
Put everything on a scope and you can see all of this.
The same is true of Futabas and other brands so it is not endemic to any one make or brand.
The original problem with Spektrums was the longer reaquisition time which was cured long ago.
