Here's the screen after a flight and voltage auto-landing mode. With a voltage of still 14.7 left, shouldn't it still have enough power for at least 2-3 more minutes?
Just at a quick glance without being familiar with your craft, I would say that your being a bit conservative with your voltage settings, that is if you do a lot of close proximity flying. Your drop dead voltage before cell damage would be around 12.8V. If your loss is correct, then you can move the First Level protection down to 13.3V and then your Second Level down to 13.1V. That should give you the extra flight time you need.

I have exactly the same settings on my WK-M X8 setup, which uses two 4s-3300 45C packs in parallel. I get about 8-9 minutes before the yellow flashing starts. About a minute before that, I can see yellow flashing if I do a fast climb. You may need to lower your settings even further, or maybe try the calibration procedure, where you measure the resting voltage of the pack with a volt meter, and enter this into the appropriate spot on the Assistant VM screen.

Thanks! I will try your recommendations!

Getting 7+ minutes flight time now on one 5000MAH 4c. Much better.

Hi. Interesting use of Heli tail assemblies on your camera mount Will you be driving them with belts?

I'll be adding some FPV hardware, so after I calculate my final weight and CG, I'll post my settings.
How are you finding the xaircraft camera mount?...Thanks

Yes the axis will be belt driven but the srevos will be mounted very close to the axis.

Best regards / Kajaken

I'm very happy with it. For the price, you can't beat it. It assembles easy and snaps right on to the x650 with no problems.

Love to see your vid of that mount. I always wanted to get that as I am stuck with a bulky mount.

Its 192GBP here so not that cheap, does it do a good job of vibration damping? Thanks for your help, just puchased a Gopro HD2 and need a good mount....

Here's a picture from my third flight.

This is in GPS mode...it was so confidence inspiring that I reached into my pocket, dug out my phone and snapped this picture.

Tried a video but then it went into fail-safe mode for some unknown reason and executed a flawless RTL...which was extremely cool to witness because I'm not sure if I would have intentionally tested that feature anytime soon haha.

REALLY need to sort out why it went into fail-safe though.

Well, I guess I should have said that the price was relative to the other available self leveling camera mounts out there. You are right, its not cheap. The mount does a decent job with isolation. I have no complaints.
