    Every time I have Lost Control signal after 400 metres with my F210 3D and my Devo 10. So the drone go in fail safe and drop down in the field. I use Goggle 3 in fpv mode and the new osd indicated "Lost Control" before the Landing.
    Is normal a fail safe at this distance? I belive that the range of Devo 10 was almost 600-700 metres.
    Any solution?
    In the model menu of Devo the power amplifier is setting on 20 dbm, the max power of radio.
    Thanks

    The max range of the Devo 10 is 2klm. Its an extended range TX.

    But that is for the FCC TX and a Devo 1002 RX full strength extended range RX with diversity antennas.

    The CE EU version of the TX. (noted by the B versions in the TX firmware) is only good for around 800 metres.

    The receiver in the F210 is not full strength so about half the range so in the EU thats about 400 - 500 Metres effective.

    You cannot load an "A" series FCC FW on a "B" series CE TX. But you can load the Deviation FW on the TX and this will allow a power boost / range boost. Or so I believe.

    Cheers Brian

    The TX in My Walkera F210 is TX5825(FCC), not the european version, because I have buy the drone in China.
    So I believe that was in full strength. The receiver is the DEVO-RX713.
    Why I lost the signal after only 350-400 metres?
    Thank

    The TX 5825 is the onboard VTX transmitter and has nothing to do with Radio range. Its for the FPV transmission.

    You need to check the FW version in the Devo. and see if it is version A or B.

    Cheers

    Vendor - 0483
    Product - ID df11
    Version - 0200

    Thank.
    software ver. 0.8A
    lib.Ver. 0.2

    So the firmware ver A on the TX of my Devo 10 is able to do a full strength of signal. Is correct?
    Remain the doubt why I lost the signal after 400 metres with the full range of my radio.

    Yes that is the full power capable FCC radio.

    I can only suggest that you check the antenna wiring from the RX for damage.

    The antenna wiring appeared ok. In the ground I have just obtained a distance of 300 metres.
    It seems too short range in my opinion.

    300 Metres on the ground is a good range. that would equate to over 1 klm in the air.

    Are you getting the dropouts in the same place all the time? Have you tried flying at another location?

    Are there power lines nearby?

    Cheers
