16-17 minutes would surprise me. Maybe with only hovering and draining the battery to the absolute minimum. 10 minutes is ok for most flights though, at least for me.
It doesn't surprise me. It's ALL a matter of how you fly and the conditions...
we really do hit
19-20 minutes (17-19 before the first red sequence, only a minute or two before the second). And we aren't flying light (we are pretty maxed out).
Note that there are 19 minutes 15 seconds of video (and 36 seconds more worth of tagging/title cards), and there's beginning non-flight video time chopped (2.5 minutes while the co-pilot was taking his time setting up his camera to videotape the launch). Oh, and a small video segment chopped someplace in the video itself. We hit a little
over 20 minutes in this flight.
We were far from just hovering. And it's quite breezy as one flies over the edge of the Long Island Sound

The attached image below is our copter in "extra heavy" mode - we only flew it like this once, and not for a full flight. Some "minor" problems (TBE) thanks to a compass not mounted in the correct place - we crashed halfway through a battery. Our planned standard configuration has taller "stock-like" landing struts instead of the carbon fiber heavy ones, and everything else you see in the picture.
Our next flight will be the hybrid (of our earlier) configurations (our anticipated standard configuration):
- the taller and wider "stock-like" legs (no carbon fiber legs from the pic) - our earlier flights, like in the video above, were with the smaller and shorter stock legs
- all of the carbon fiber extension plates (front gimbal extension and rear FPV xmit extension)
- the FPV components
- H3-3D gimbal
- NO wrap around lighting strip (we damaged that one due to the TBE crash)
- Keeping the big flashing underside LED disc.
With the planned "hybrid config" outlined above, we expect 18-20 minutes with similar flying, from launch time to land time (plus be able to have a minute or two idle, motors-up time).
Here's our very heavy flew a few minutes config:
