rc-hydro Victory ESC turning off

[jacobo.jajati]

(had Posted this in the wrong forum)

I need some help on my RC-Hydro ESC.

After about a year of not running my boat i decided to dust it off, buy some new cells and go to the lake.

I purchased this ESC to replace a stock traxxas 14.4 v Villain EX ESC.

I have run this boat before with 14.4 and 7.2 (for the kids) and it has always worked great.

I have been running small test runs on 7 cells and when i run the boat at 80% it runs great but when we i go 100% it runs for about 5-10 seconds and stops, even with no load outside the water. It look like it cycles through the start up process like when you plug the cells for the first time after a charge

Any help to what might be greatly appraciated.

My Running Gear is:

RC-HYDRO ESC
two Traxxas 14.4 (original EX motors)
Traxxas two channel Reciver
Standard EX transmitter
Offshore Electrics Villain Carbon Prop Upgrade Kit
Water cooling comming first to the ESC then to the motors

thanks again

Exactly which ESC do you have. If it is a Victory it has a cut off voltage for lipos that may have been programmed in.
But I need to know which ESC you have?

If it is the 60 amp Victory model the problem is likely that you're battery voltage is too high - it's only rated for 14V input voltage if I remember correctly. I notice it doesn't work now that you have new cells.

I had this problem with the 60 amp model running it with 12 IB4200 cells. I could recreate the problem on the bench without the motor even connected. With full throttle on the transmitter the LED would be solid green for about 10 - 20 seconds, then would start flickering yellow, and then would go to the flashing red mode. This was with 12 cells. With 7 it worked fine. The LED stayed green indefinitely and it never disarmed. I traded it for one of the models that could handle 10-24 cells and 90 amps and had no more problems.

If you have the 60 amp Victory model you might want to try the test I mentioned.

yes it is the victory 60 amp and im using 8.4 v nimh (7cell)

yes exactly is what is happening

10-20 second and yellow and blinking red

but it never happend before the new cells

and the ESC is cool not even warm to the touch

[jacobo.jajati]

just put the ESC on the bench

16.8V

for 3 min, 100% on the gun

no reset?

Jacobo,

It sounds like your problem is the new pack. Check the connectors, check for a bad cell (do you know how?), etc. Or you have too much load (prop) on the motor.

The ESC is resetting because the incoming voltage went too low. A bad cell that cannot deliver the power is the most common cause, but bad connectors will often show the same symptom.

When people had this problem recurring and they couldn't find it, I would often have them send me the motor, ESC, and batteries and I would pinpoint the failure for them. I don't do that any more (I shut down RC-Hydros.com completely this past winter) but I'm happy to help you learn how to do it yourself.

Andy,
I have a Victory ESC and the instructions say "not recommended for AM frequencies", can you explain the reason? Not compatible or too much noise?
Thanks, Brian

[AndyKunz]

Too much noise.

I wouldn't recommend AM for anything.

Andy

[bwells]

Andy, Thanks. I was leaning that way but thought I had better check!

[bwells]

I have the Victory V90-1032 and just purchased a 2.4 GHz trans/receiver, hooked everything up and I get a flashing red LED. The instructions say if you are using an old style Airtronics receiver, to move the brown wire to the center position on the connector. Have not done this. Could it be that the 2.4 GHz receiver mimics the old Airtronics stuff and this could be my fix?

[AndyKunz]

This is NOT an Airtronics-style thing. They used to use a different pinout than the rest of the world. They are now using the same standard as everybody else.

Which 2.4g system?

The ESC needs to see a valid signal. Did you bind the receiver and transmitter? Are they both turned on? Is the servo working? Are you sure you have it in the right channel? Have you cycled the throttle? What happens if you put a servo into the same location where the ESC is right now?

Andy

[bwells]

I have a Tactic TTX240 2.4 GHz transmitter and receiver and I did bind them, the servo works fine and I moved the servo to channel 2 and it works there as well with the throttle on the trans. Not sure what you mean by cycle the throttle but I did pull the trigger and the LED still flashes and does not miss a beat. I'm using a BEC that puts out 6 volts and 2 7.2 NiMH batts in series.

[JimClark]

try adjusting the radio throttle end point

[bwells]

By turning the trim adjustment on the trans? I miss spoke earlier, the batts I'm using are 7.2 ni-cad and only 1800 Mah. I do have 8.4 4500 Mah NiMh, but I'm gunshy about burning up my OSE 700SC as I'm not sure what voltage it can handle. That is what I would like to use in the end.

[JimClark]

yes on the transmitter
