    Urgent help with ESC Seaking V3, from 180A (to fail)

    on April 2, 2019

    I live in Brazil (I'm sorry for English errors), I'm trying to build a TFL Genesis, but with a lot of problems, I think it's ESC:
    Propeller Shaft: OSE
    Engine: SSS 4082 2200KV
    Lipo battery: 2 x 3S - 50C 6000mha
    Propeller: 1716 from Pro Boat (from Veles) and X642 (octura).
    ESC: SeakingV3 180A
    ESC Settings:
    1 - Forward and Backward (default)
    2 - Auto Calculate (default)
    3 - 3.2V/Cell (default)
    4 - Timing modified to 7.50° (default is 15.00°)

    The boat fell into the water - soon after 10 seconds it started to fail, I believe it is ESC.
    You have a video and pictures attached.
    Can someone help me? Did I do something wrong?
    I think I'll go back to the lake now (after lunch) and try other settings .
    Is it true that this ESC fails anyway?


    to complete: At other times, the ESC failed (quick cut) but the boat did not stop. ESC, Engine and batteries did not heat up. The only thing I noticed that warmed up a bit was the two capacitors in the wiring of the ESC.




    Propeller Shaft: OSE
    Engine: SSS 4082 2200KV
    Lipo battery: 2 x 3S - 50C 6000mha = 22.2v
    Propeller: 1715 dasboata.com
    ESC: SeakingV3 180A
    ESC Settings:
    1 - Forward Only (default forward and backward)
    2 - 6S Lipo Cells (default auto calculate)
    3 - 3.2V/Cell (default)
    4 - Timing modified to 7.50° (default is 15.00°)

    Hi all,
    Today I did several tests, unfortunately all without success.
    It was running with 2 5600mA 100C - 7.4v (2S) batteries.
    Notice in the video that with the boat "totally cold", in 8 seconds it already fails ...

    1st test - ESC configuration:
    1 - Forward and Backward
    2 - S4
    3 - 3.2V/Cell (default)
    4 - Timing modified to 7.50°

    2 X 5600mA 100C - 7.4v (2S) batteries


    I then moved to:
    2nd test - ESC configuration:

    1 - Forward and Backward
    2 - S4
    3 - LVC
    4 - Timing modified to 7.50°
    2 X 5600mA 100C - 7.4v (2S) batteries

    Unfortunately I do not have this video, but the boat kept crashing, I accelerated at most, it was too slow for 4S (but it was fast, I mean slow because it was a SSS 4072 2200KV engine). It ran for just over 1 minute, stopped for a few moments ... but there was no speed expected from this configuration. After 1 minutes the boat stopped. I had to rescue him.
    When I opened it, I noticed that the battery plugs melted ... check the image. It melted not only the plugs, but also the battery case. But it was not fast for this havoc.

    -----------

    3rd test - ESC configuration:

    1 - Forward and Backward
    2 - S6
    3 - LVC
    4 - Timing modified to 7.50°
    2 X 6000mA 100C - 11.2 (3S) batteries


    in 5 seconds it failed again, I returned with the boat.

    --------

    4th test

    1 - Forward and Backward
    2 - S6
    3 - LVC
    4 - Timing modified to 3.75.
    2 X 6000mA 100C - 11.2 (3S) batteries


    in 5 seconds it failed again, I returned with the boat.


    ---------

    I have 2 things to do and I wanted suggestions:
    Remove this ESC and put a Flycolor 150A (it's the only one I have in Brazil for now);
    or
    Redo the connections (solder again - I thought there might be some failure in soldering of the EC5 pulgs ...
    On redo soldering of the plugs - it is laborious and I will lose the plugs that I soldered, but it would be possible in this picture (which burned / melted 2 2S batteries (the plugs) having failed my solder? These plugs that I soldered did not melt, I believe that the service is good ...

    thanks

    Set timing to 0*, turn off LVC and time your runs.

    Hi Peter A

    thank you very much. I'll do this setup.

    Hi Marcos,

    How high is the the propeller from the bottom of the hull ?
    You should have 5mm high from the bottom of the hull and 0° angle.

    I don't have SSS motor, but I have 15° timing for a Leopard and 3.75° with TP.
    Both are 4 poles, but it depends on the brand/manufacturer.

    IMO The pitch of your props is high to begin the settings of your boat, this overload the motor unnecessarily
    Try a 1.4 ratio pitch/diameter like octura X445, or 45 aluminium prop.

    For a 2x 2S setup try this setting:

    1- Forward only.
    2- S4
    3- None
    4- 0°

    If it works well, change the cut-off value to save your batteries from deep discharge.

    regards.
