    Hi Guys,
    I have got fed up waiting for the official call back from Yuneec UK so I took a gamble on the downgrade of flight controller firmware.

    I can confirm I have successfully downgraded my H520 back to firmware 1.1.11 and no longer on 1.2.0 and my battery % is now correct again, I will test over the next few days whether that has improved the jpgs from being cloudy as well.
    With the battery % back to normal I should see improved flight time again from 11-13 mins back to around 22 mins. I will expect less in the cold whether obviously but not by nearly half.

    To do the downgrade format an SD Card and load 1.1.11 onto it. Put the SD card into the camera boot the 520.
    It will do a series of light changes in a circle and when its finished will give the reassuring 2 bleeps. and the camera light will flash green.
    Shut it off, remove the battery for 30 secs and put in the normal SD card you use, reboot the aircraft and then do aall the calibrations and your good to go.
    Hope this is helpful to you

    The 2nd picture is of a storage battery percentage. When I booted it originally it was at 45% which to me is correct.
    1.2.0 reported it at being 33%
    So things are looking up.
    I now also have the toggle manual angle mode back to cancel RTL.

    That's good to know. My flight times plummeted too. Was getting 24 minutes before upgrade. Now it's about on par with my DJI Spark...

    Case to follow, thank you
    But did you keep the alarm level low (16%) or is it raised to 30%?

    Didn’t check that Claud was too busy trying to recalibrate everything.
    It’s basically gone back to the toggle method at 27% so I’m assuming I am back to auto land at 21% which can be toggled out
    I’m happy to be back there if I’m honest.
    I will check the levels next time I fire it up bud

    Levels are back to 27% and critical back to 21%.....I can live with that and gain 10 more mins flight time

    So after testing the 1.1.11 firmware today I can confirm flight times are now back up. 2 screenshots below.
    1st screenshot was 520 liHv battery at 28% and 19 minutes.
    2nd screenshot was H480 battery at 20% and 22 mins flight.
    Even in temp outside being 5 degrees C I doubled my flight time from firmware 1.2.0
    Ok so I had toggle at 27% to cancel RTL but hey small price to pay.

    Not looked at the Sd card yet Dave. That’s tomorrow’s job.
    I was testing the new E50 I have mostly but did take some with the E90
    Will report back here tomorrow

    E90 is showing no signs of improvement Panomapic so no point of uploading them.

    It’s a big fat orange lemon on that one

    However I did find an error on the E50
    On another thread which I hope the chap reads here because I can’t find his original post he mentions he is losing connection with his E50.
    I too lost all connection and an RTL was initiated at 150m. Yeah I know wow.
    I saw he was on gimble firmware 1.33 which is not even on yuneecs website. The reason is there are bugs in it.
    So I downgraded to 1.31 gimble and the connection is much better.
    He was also on 0.4.0 camera firmware and I suggest he installs 1.0.01

    Dang, that's disappointing. Do you feel like the jpegs from the E90 are useless for mapping as well?

    They have different antenna design on the E50, I find a far better signal is achieved using the directional antenna on the ST16 and always pointing it to the camera's location, where as the E90 is far more forgiving when using the circular polarised, unless of course you are using the 4Hawks which is just great with all of the cameras.

    Thanks Dave,

    I'll take a look at them later tonight; the wifi on the plane can't quite handle the images haha.

    With which program have you processed the images?

    I ask you because I have processed a few projects with Pix4D and E90 with an almost identical GSD and I see the images with more sharpness. I have looked at the car, at both images and compare it with what I have processed and see more sharpness and resolution in mine.

    I used Drone Deploy for these, this was flown at high speed, shutter was not properly set for the conditions, I would imagine this is motion blur. It was cold and I did not want to be outside that long :)

    I have woolen gloves that only reach half the fingers, like those of car drivers. For fingertip sensitivity. Enough to hold on for a while :)

    I was looking at some with heaters and a USB cable to plug into a powerbank :D

    Is it your opinion that this is down to the E90 not being fit for purpose? I ask because I am considering whether or not to back it to my supplier under the relevant consumer act.
