You're probably right, this has turned into an electric power system discussion. Your also right that an electric motor will draw what it wants to draw given a certain battery prop combination WITHOUT limitations. However, I've measured the amps the system is drawing with a fluke clamp meter and that is how I knew where to set the throttle endpoint so as not to burn up the motor. My next toy will be a wattmeter to see what it's doing in the air. So my system, without endpoint limitations will certainly draw more than 35 amps, I've just chosen not to go beyond 35 amps to play it safe with my motor. My goal here is to stay in the air as long as possible between charges, which is why I wanted to know if a 13x8 prop would be more efficient at doing this with my lazy high wing floater than the 13x6.5.
