It's pretty standard for any electric copter these days. It's a simple matter of energy density.
If you go on hobbyking.com and build a standard-size quad from parts, you won't get much more flight time than that. Somewhat better, sure, but not a whole lot.
This is reason #387 why we need a revolution in energy storage.
- bri3d 14y agoI get 13 minutes out of a 3300mAh 3S Turnigy "nano-tech." 10x4.5 props, 1100kv motors. My payload capacity isn't particularly high but a GoPro sans case is only just over 90 grams, so it works fine. I do agree that we're reliant on advancements in energy storage to push the flight time envelope, but improving even nearly twofold on 7 minutes isn't particularly difficult.
- Florin_Andrei 14y agoSo how about this: http://www.rcgroups.com/forums/showthread.php?t=1666155 http://www.rcgroups.com/forums/showthread.php?t=1666155 Very simple chassis, Depron and some wood sticks. 1500kv motors. 5x3 props. Turnigy nano-tech battery, but with a choice of two models: 1. Either 1000 mAh weighing 79g 2. Or 1400 mAh weighing 119g. Which battery would you choose?
