    Ok. There are a few things about this that just don't add up for me. First is that one bad sat on a vbar should never cause a crash. The receivers talk to the vbar using a fixed protocol and all packets received are integrity checked before being passed to the vbar. The receiver also sends malformed packet codes to the vbar so they can be entered into the log. ( ask me how I learnt this). With two receivers doing this the vbar can decide which is the most reliable signal. The vbar then switches satellites and puts a message in the log to say its done this. (FYI : it allows a certain amount of bad packets before switching. ).

    Satellites. My understanding of the flashing light is that it's received a power reset rather than a lot of malformed packets. Or it has completely lost the signal. Which again will be reported in the vbar log. Can you post the log please. Along with a commentary of what you were doing.

    Things to check.

    Power.... Are the leads to the satellites ok.
    Power bus on the vbar. Did it get damaged in the crash. Mikado are very good and will have it back to you in less than a week for a checkup.

    Plug your laptop into the vbar when your doing the range test and look at the monitor screen to see what the vbar thinks your servos should be doing against what they are doing

    Put the satellites into dsm mode in the tx. Leave them as dsmx on the vbar (this just sets what satellites are plugged in rather than their operating mode). And try again. (firmware on the radio)

    Borrow some dsm2 satellites and try again

    Try another transmitter. ( some are just pants on range test)

    hope these help.

    Again post logs. (did it show a satellite failure in the log for the first crash! )








    Ok

      One bad sat did case a crash last time as I sent it all off to horizion hobby and it turned out o be a faulty satite. But this issue is using a new one they sent me. And it has not caued a crash yet as i have not tired it i was just getting a short range check also we didntry it on a different dx8 and we got the same results ohh and I can not recall any issues in the log but I may be wrong and will look tonight but they may have gone as I have been messing about with it


      So far I have swapped tr fuel tube for some thin clunk tube and moved the sats to
      A better position and checked the wires
      Tbs discovery quad
      Align 700L Dominator
      Gaui x3

        If there was a problem with a remote receiver it should be in the log, and as explained by the member above it should just switch to the other one.

        Maybe there is a V-Bar issue here.

        Anyway I hope the new changes have fixed it.

          I would get the vbar checked out.
