RE: Big Power from new Phoenix HV ESCs
Actually, you keep the Amps the same and use more cells. That allows you to fly bigger, heavier planes.
45 Amps is not "low current." It's about average for your typical .40-.60 size sport conversion. 45 Amps isn't excessively high current either. You get reasonable flight times with batteries of reasonable weight. None of the components are being stressed or overheated...
