New Spektrum DX3r Observations

[BrianG]

I don't know. Considering actual RF output is measured in milli-watts, the battery voltage probably doesn't affect range (Spektrum has confirmed this). So, the gains must be in the display and/or circuit topology. Maybe the new radio has more of the circuit integrated onto one IC, which can save power over discrete components. I've only had it a very short time, so I don't have any data about the "runtime".
