[QUOTE="mimixtz, post: 35110, member: 7144"] I think transmitting has nothing to do with distance. It is as it is. But I could be wrong. Power used for trransmitting is very small I think - even in FCC mode. If we are talking about 600mW in FCC, then approximate calculations could be (but it could also be wrong): U=11.4V P=0,6W I=P/U=52mA Even if we double it because of the heat losses of the transmitter, that is only app. 100mA. I think 1 motor only can pull up to 10 Amps or even more - for comparison. I can't find details about motors and speed controllers so I'm not sure. But since racing drones of similar sizes have 30 or more Amps speed controllers... I don't know. Motors are main loads. So more acceleration and breaking - shorter flight time. Next to them I think we could list gimbal motors. Which again means: more movement, more work for them. And then processor (flight controller) with its heat losses and consequently cooling needed. Logically: more action, more work for flight controller. Leave your Spark just connected and you'll se how warm it gets. And this tiny fan blowing on maximum all the time. [/QUOTE]
