Hello gentlemen, I've got an E-streak that I built with a Thunder Power 2S3P 6000mAh battery, FMA super 30 ESC and M5 receiver and the stock goldfire motor w/8X4 electric prop that weighs in at just over 2 pounds (2.07), and it flies great. I wouldn't call it great vertical, but I never worry about losing altitude doing maneuvers because it’s so easy to gain it back. With this setup, I get tired about the same time the battery does. I haven’t timed it yet, but I’m guessing flights are at least 15 minutes. With a fresh pack, the Whatt meter is showing about 225 watts full tilt. After a few minutes it settles in at around 200 watts for most of the pack. How does it fly? It’s pretty much like they say. If you can get 100 watts/#, it’ll fly nicely.
