FPV problems with the UpAir One – Easy Fix

Posted on Posted in All Posts, How-To, UpAir One

Many have heard and read about the FPV issues with the UpAir One drone.
Some people take apart their expensive drone to do all kinds of mods to improve the feed, and the stability of it. they buy more powerfull VTX modules and stick on antennas…

But there is a faster, cheaper and effective way to deal with it.

All you need is some cello tape, super glue and an old computer mainboard.


To extend the range of the FPV signal simply take the antenna out of the leg, and stick it on the outside. you’ll notice an improvement straight away! I have had over 250 meters range without a glitch. might even go further, but I haven’t tried that yet.

But in order to keep that increased signal you also need to keep the transmitter cooled.
There is a small alluminium casing over the transmitter, but that doesn’t do the job.

The trick is to increase the size of the casing.. and not with small sticky heatsinks, but with a heatsink that is bigger than the case you stick it on.
This will increase the size, and due to the ribs it will cool very good!


I have had the drone sitting on the table, without props for over an hour with the feed on, and it worked flawless. imagine the extra cooling when flying!

These simple, yet easy mods should take care of your FPV issues in no time!

Here is a small video of my UpAir with the heatsink fitted

  1. An “old” newbie needs some help : after repairs, my UpAir One OSD shows “no MAV data” and the drone does not function at all. I have the view from the camera but this is all. Has anyone experienced this before ? … and found a cure ?
    Cheers, JP (an “old” newbie is someone above 65 y and with less and less acceptability of problems)

  2. Good morning,
    Thanks for the answer. I have succeeded yesterday in pairing transmitter and receiver, I am now able to start the drone motors. On the transmitter, I have the picture sent from the camera and the gimble operates OK. On the screen, I do not receive any telemetry indication, except the transmitter battery voltage and the mention “no MAV data” in the middle of the image. I have uploaded via Mission Planner the correct params obtained in a post from Cruzroy on the subject. If I stop and restart the drone, I get the same.

  3. Thanks a lot. Yesterday I opened the drone once more and found a mistake in the connectors. I have now the telemetry as before but it seems that it does not show the GPS antennas and the position although the compass, the camera and the drone battery voltage work. I probably have again a mistake in the connectors.
    Is there anywhere a photo showing where the 6 pin connector on the left of the main board (looking at the main board with the battery plug facing up) is connected ? I think there are only 3 pins used and the underside of the board shows the markings “DTR, TXD and RXD”. I have not connected anything to this plug and yet I get the OSD even if “no MAV data” flashes for less than a second when the drone is switched on.
    I have not yet switched on the drone for an extended perod of time outside but, with Mission Planner, I know that the GPS receiver is OK.
    Many thanks again for your help.
    The problem of getting a bit old is that you do not think about taking photos when dismantling. Then you realize that your memory is not as good as before …

  4. As I said before, memory not very good ! I forgot to mention that the Main Board is version 3, V1.0.02

    1. Hi, Hv you solved the problem of “No MAV data” issue.
      I have almost the same problem. My drone is V3 with Upair2 PX4 V1.2.0.0 board.
      Once I start the drone “No MOV Data” flash about one or two sec on the OSD. I can see all data till I press ‘Video’ button. After pressing ‘Video’ button, my OSD freezed. I still can control the drone but OSD is dead. Dangerous as I don’t know what my drone is sending to me. Even I restart the controler, still doesn’t work. I have changed the Vtx to TS5823L but doesn’t improve.
      Anyone encounter such?
      Please guide me what should I do?
      I am unable to fly more than a week cos of Vtx problem.

  5. Not solved completely … By changing the positions of the connectors, I now get the full OSD view and the gimbal works OK. But I am not getting any info on the number of GPS sats connected. I am not too keen in trying the drone outside like this. Suggestion for you : make sure your connectors are in good condition and that the contact male-female is good. Check that no wire is damaged or unconnected, particularly the VTX antenna.
    Good luck
    Cheers, JP

  6. Hi Olaf, at last got new Upair one 2.7k flies great but when recording the video turns out very erratic, all stops and starts. I have noticed that the record button and camera button does not always work. Could this be a bad connection in the controller which is causing this as the camera picture on the monitor is perfect while static.

    1. Hi,

      The erratic video could also be a slow, or bad SD card.
      I have had that 2 times. it will record pictures just fine, but the card can give problems with video.
      Try that first.

  7. I recently bought an UpAir One, I believe the one with the PX4 board on it. First test flight went fine.

    With this being my second UpAir, I wanted to do the USB mod. Had to custom wire this, because it had the DF13 connector on the FC board, instead of the micro USB. Connected to Mission Planner just fine and things were looking good.

    I powered on the quad (perhaps this was a mistake?) I got “No Mav Data” on the screen, and ever since, with one exception, I’ve not been able to get any OSD data on screen nor can I arm the motors.

    Sometimes when I start up the quad, I get NO MAV DATA, but if I power off and back on, I get OSD painted on screen, but all data is “flatline”. Here’s an example video:


    If I connect only to MP with quad off, I get telemetry, satellites, and everything. But w/o MP connection, can’t get true telemetry data and again, can no longer even arm the motors.

    I’ve been over everything a dozen times, removed the USB mod, etc, checked voltage feeds. I’m out of ideas.

    You can also see my comments starting post # 3200 in RCG:



    Any help would be appreciated.

    1. First of all, credit where credit is due.

      G10 customer support stuck in there with me long enough to help me get enough information to finally spot the problem. So a big thanks to Lily!

      In the end, the problem had absolutely nothing to do with the USB mod, connection to MP or even anything in the drone. I couldn’t run the calibration or re-binding sequences (https://www.rcgroups.com/forums/showpost.php?p=37549964&postcount=3203
      ) which also came from customer support and the tip came in that there could be a bad gimbal in the controller. So I took that back apart, and finally found one tiny strand of wire shorting between the signal post and ground post of one of the gimbal axis. I cleared that short and ALL the problems went away.

      I can now arm motors and have full telemetry on screen!

      Battery is charging now for a resumed test flight. As [I believe] this is the PX4 version, I’m hoping to compare wind stability vs my original one on the 8-bit APM board.


  8. I flew my UPAir One once yesterday. When I tried to fly it again and powered it on, I did not have telemetry and I could not arm the motors. I took it apart but did not find any loose wires.

    Any ideas of the cause?
