    Hi all so I have finally found the final hurdle. The local club member had another look at my plane after getting further advice and found it was between my receiver and transmitter. The reason for this is futaba have been known to send receivers that need resetting as they have been set up for 16 channels where two 8 channels receivers buddy up to make 16 channels. My receiver was set to above 8 which is why my 8 channel transmitter couldn’t calibrate my esc. After resetting my receiver and changing it to channels 1 to 8 my transmitter calibrated and armed the esc correctly. :)

    Still sounds like a reversed channel.

    Hi all

    For those that were wondering what the fault was well...
    I took my plane to my local club and I had two seniors who have had 30+ years in this hobby and they diagnosed the fault which was the planes freewing blue control box which was preventing the signals to the single wires to the receiver. So they bypassed this control box with y plugs straight to the receiver and the plane works fine. However this was with their receiver and controller my controller and receiver still makes multiple bleeps due to futaba set up the seniors did not know how to set up the esc with futaba. However there is a younger club member who is coming round today who will be able to calibrate my futaba set up as he is the only one that uses futaba.

    Precisely! It may only be one piece of evidence. You would likely win your bet. (if you were a betting man.)

    I think this YouTube video at time 09:10 https://youtu.be/U6djMJYYaiA

    is what’s happening with my esc I inspected the wires last night and they seem well connected I have a voltage meter I found secure connections. I have found a club 30 mins drive from me to take it too. Might subscribe to fly there also I already have my CAA license for (Uk)

    Dir sir

    I never asked you to prove it to me, I did my own test and got some same and other result than you.

    Kind regards Hans

    I just tried to video this phenomenon but I can't get it off my Iphone so I can post it on YouTube and embed it here. I'll try it again later with a different video camera.

    In any case, I knew I was NOT dreaming this up. If a certain wire on the motor to ESC is disconnected and I attach the battery, it gives a rapid beeping (cell count) on an outrunner EDF, it is just as loud as if all three wires are connected. However, this ONLY happens if a particular wire is pulled. If either of the other two are pulled, there is no beeping. Nothing happens.
    In the case of the OP, this "could" be what's happening.

    Unbiased arbiter here.

    FW 70mm 12B inrunner with Avian 80A ESC.

    3 leads attached - loud beeping.

    2 leads attached - very faint beeping (had to put my ear really close to hear it).

    The beeps come from the motor windings being energized at audio frequency by the ESC, The ESC itself doesn't make a noise.

    I'll have to give it a try with both outrunner and inrunner EDFs. It could be I was hallucinating.

    Hi

    Don't know what triggered you regarding you're answer.
    But I just checked it with 2 different ESC'n, using a brushless outrunner and with 3 cables connected I got beeps and with 2 nothing😉
    Maybe with a EDF unit and inrunner it is as you say but I have to test that next time when I have my EDF on the table😏

    Thank you all for your advice I have no experience only with small planes and virtual simulators. I have much to learn. I will look into the throttle curve I read the manual again last night and seen that part. I think for myself I should go to a local hobby club or shop if this doesn’t work as I appreciate it’s difficult to translate over text. I will keep you updated in case it’s something more than it is.

    Hi

    For us to help true the internet is a hard way to do and nearly impossible to a person who is new to this hobby an has totally no experience what so ever.
    The only advice we give is go to a local club and let you help there, that's the only way to be save.
    What is yours building experience, technical back ground?
    what are you're flying skills?
    what did you fly before!
    etc etc...

    Regards Hans

    ps before you can arm a ESC you have too make sure that the Throttle curve is programmed into the ESC.
    Its explained in the manual of ESC

    I own a futaba myself and you have to reverse throttle channel in order to do this.

    ps2 if the motor beeps than normally the wires are connected as they should otherwise you did not get the beeps.😉

    What is the model? Generally you can access the fan unit by removing a hatch held in place by just 2 or 3 screws.

    What planes have you successfully flown previously?

    Your questions suggest you need in-person help. Would you expect to fly a full-size plane with just instructions from the internet?

    A loose wire is not really a "faulty" product. I've seen those wires come loose during transport on a few planes because they weren't pushed on firmly at the factory. Being new to the hobby, you likely just don't realize that these sorts of things are natural occurrences and is part of the inspection and set up process with any RC model.

    yes you are right it may be a faulty product from motion RC

    Then you can't really tell if they are all connected or not. You have to remove the EDF hatch, take out the EDF mounting screws, lift the EDF up so you can see the 3 connectors. If one is loose or not connected, that might give you that fast beeping.
