I was holding out till NAB before purchasing another battery in hopes that a new hi-capacity battery would be announced. It looks like instead we have some tether system that allows for little height or distance from the launch point that costs nearly twice as much as the drone. I'm very disappointed with 3DR on this front. My batteries start out at just under 15 minuets and over time reduce to 8-9 minuets of flight time. I have toy drones with longer flight times. Has anyone come up with a solution to these dismal times aloft. I'm looking at options such as weight reduction. I know "the weight makes it more stable you want it heavy," wrong I'd give up some stability for longer duration flights and just fly on calmer wind days. Other options such as battery modifications. motor replacements, props. I'd like a true 20 minuets of useful flight, that would be a 33% increase over what I'm getting now with a new battery.
