I am soooo hooked! Started this morning, flying my little bitty Hubsan X4 around in the house, couple of batteries worth. Then after coffee, took my F550 hex out, and flew it around in the yard. It has to be the most stable of all my multirotors. And with 2 2100 4 cells in parallel, can get a good 15/20 minutes. Brought it in, and got out my T580+ with 2 3 cell 2100's. Flew it around, goes forever with no load. 14" props, a little slow to respond, but look out when you nail it, tons of lift off! Flew it till the low battery beep. Came back in, and got out my Phantom 1.1.1, with an Immersion 600mw TX, 600TVL camera mounted on the battery door, and flew it with my Skyzone goggles, from my back deck, all the way around my house, thru the front yard, and back. Just having a ball! Now charging batteries, for more fun! I have learned so much from this site, but still have a lot more to go.When the other 2 multirotors come, that are ordered, I'll be up to 7, 6 quads and 1 hex. Good thing I'm single. When I was married (3 times), I was never allowed to have this many toys!:tennis:
