    Hi does anyone know if I can get the left esc signal wire working on the pwm or another part of the board? the left esc signal pad will not work anymore. i soldered the left esc signal wire to the right side and it worked fine, but when i solder to the left signal pad the motor will not spin up.
    is there any other way to get this to work? it didn’t even crash or anything and i had the pads all covered with hot glue and it was flying fine. now the left esc doesnt respond!?!
    this is disappointing… to say the least… 🙁


    I’d be glad to help. Could you post some pictures? Thanks!


    Does noone have any reply to this? Can i or cant i get to the left esc signal any other way?
    Seems like quite an oversight for an integrated board to not have any alternatives for powering the escs…
    Its the f3fc board, theres lots of pictures of it.


    @fallkon The reason why I asked for pictures is that it would give me more clues as to what the problem could be. Since you mentioned hot glue on the joints, I would suggest to start with the following: use some de-natured alcohol to remove all of the hot glue. This will allow you to more easily solder wires to the pads. Then re-solder the left ESC signal wires to the F3FC. Let me know if that fixes the issue. If you’ve done tests with the same ESC and wires soldered to the right pad and everything worked fine, my only conclusion is that it’s the left pad that’s causing the problem. Because the board worked fine and there were no crashes, I’m guessing that it’s a poor connection between the board and the wires. Again, it would be a great help to see pictures of your build in diagnosing and fixing the problem.

    Good luck! Hope that we can get it resolved. By the way, I’m not completely sure but I don’t think it’s possible to get the PWM signal to the left pad in any other way, unfortunately.


    @fallkon Have you tried opening a support ticket with RCExplorer support? They would certainly have some good input.
