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.
