Video Power consumption

[RSubkow]

So first let me open with - I'm a new Phantom Owner
Second - FPV is a must
that being said, I am looking at the Immersion RC 600mW transmitter and wondering just how much time that and a Mini iOSD will take from my battery flight time? Any insight? thanks for helping a Newbie

With just a GoPro on an H3-3D, I got around 20min of average flight time. I added mini iOSD, 400w 5.8 transmitter, and a self-powered GPS tracker and I get around 18min on average. Easy trade off, especially because I can see EXACT battery levels on the FPV monitor.
