Kbb swordfish 300 cc 2028 780kv no beeps but it runs ?
Last time I plugged it in and the beeps were quieter now they don't beep at all

[klbo]

This is a 300 amp RC boat ESC any thoughts why it wouldn't be beeping and why was still power up I can't hear the beeps for throttle calibration

[Michlee]

Hello
Did you check if the switch is on when you calibration throttle?

[klbo]

Turn on the radio hold full throttle turn on ESC release after three seconds and it calibrates but no beeps i've switched from a stick radio to a pistol radio and calibration worked but no beeps last time out it felt like it was way down on power

[Jamey]

If you aren't hearing the tones when you power up the esc with the radio at full throttle try reversing the throttle channel. Not sure but it sounds like the throttle isn't getting calibrated. I have the same combo in one of my boats btw. What radios have you tested with?

[klbo]

Spectrum stick radio DX 8 spectrum pistol grip radio r3 when I changed from the stick radio to the pistol it definitely calibrated my neutral on the pistol was right but no beeps and the motor runs

[klbo]

I ran the boat Saturday it beeped on start up but it sounded quiet when I got home now it won't beep

[Jamey]

Hmm you said it seemed down on power too right? Is there any chance you programmed the cutoff for a higher cell count then you tested with? For example if you program the cell count at 6 and connected a 3s battery it will not beep I don't think. Also do you have the plus version with the data logger? You can download and verify full throttle if so.

[klbo]

Lvc I tried seting it to 10 lipo. and Auto still no beeps yes it's the plus data logger said 103% throttle and I wasn't getting any power 32 Mph versus 54

[Jamey]

So were RPMs way down too? What about current draw and voltage during the run?

Do you have another motor to bench test, not actually put in the boat? Might tell you if the motor is the problem if it still doesn't beep.

[Jamey]

So you are running 10s, what hull and prop are you running?

edit: You are the one running the big 58" Fountain! Very curious to know how the amp draw is?

[klbo]

Normal rpm was 27,000 it was only doing 18,000 and yes it's the fountain 58 single highest I've seen is only 186 A with an octura x455 54 mph

[Jamey]

It would be hard to believe you hurt anything running that setup.

What about voltage though? Low voltage in the log. All cells in every battery check out normal?

[Michlee]

Hello, pls check if you calibration throttle as following instruction

1st: Connect ESC to motor, plug receiver lead of ESC to
throttle channel of receiver.
2nd
Push joystick of transmitter to max throttle position,
power on transmitter.
3rd: Power on receiver, connect ESC to battery. Motor emits
three beeps in drop tones.

[klbo]

So what's a good replacement motor for a castle creation 2028 780kv

[Jamey]

If you don't want another 2028 I would research the TP5860

[oscarel]

If it's running, calibration shouldn't be your issue for not hearing the beeps. Most of the controllers the beeps come from the motor. Do you have another you can try? A good replacement is the Castle 2028 800kv :-).

[klbo]

Well I Hooked up my sensored 1/8 scale buggy motor it powers up but still no beeps

[Jamey]

I hate to beat a dead horse but have you double checked your cell voltages? And make sure it is set for the exact cell count you are using. Receiver needs to be connected and powered up as well. Still sounds like a low voltage cutoff issue to me but I am at a loss.

[oscarel]

I agree with James, recheck you setup. Also check to make sure timing is set to auto, seen issues if it's manually set. This won't help with the beeps but seems like it's still working. Do you have the USB dongle to hook it up to a computer and try to update it?

[klbo]

I do have the USB dongle I can change settings but when I go to the update screen there's nothing to update to click on browse and there isn't anything there to update . three folders and are empty

[Jamey]

You have to download the firmware file from Hifei first. Then explore to the folder you saved it in.

I have checked for 300A firmware before and it wasn't available, only 120A. I would try contacting Hifei for the latest firmware or at least discuss with them if you already have the latest. I just bought mine a few months ago so I can give you the firmware version on mine tonight so you can compare if you want.

[oscarel]

Hello
Did you check if the switch is on when you calibration throttle?

Here's your Hifei representative :-).

[klbo]

I reset the firmware it's the newest
switch is on for throttle calibrating
the motor does power on no beeps
but it runs😳

[785boats]

Are all the capacitors ok? Are any of them bulging on the ends?
I had a leaking nipple on one of the cooling plates get that end of a 240V Swordfish all wet once. A couple of the caps blew out.
The ESC would still run but would not make any beeps. Even when I added extra caps as an external bank. It needs all the caps on the ESC to be in perfect condition. I still haven't fixed it, or run it in a boat.
Just a thought.

[klbo]

Ran the boat two more times this weekend only got 30 mph instead of 50 . everything came back cool it's got to be the ESC still no beeps now I can't log onto the data logger

[oscarel]

Sounds like it needs to go back to be looked at. As stated above, did you check to see if the caps look ok? Do you have an external cap bank installed?

[Jamey]

Hey klbo, any updates on your esc issue?

[klbo]

Well I pulled the motor hooked it up to a cordless drill Spun it at 1100 RPM got 1.47 V equally on all motor wires bought an induction meter off eBay for 30 bucks pull the rotor out all wires measured the same 5.48 now I can't log onto the Data logger screens but I can make adjustments on the power side low-voltage timing etc. so I guess it would be the ESC I have to buy parts 😭 Ps it still starts and runs powers up no beeps

[Jamey]

It runs but at reduced power right?

The battery leads are doubled up on the 300SF, two red and two black. When you wired it up did you put same colors together, or at least jumper them together? I am guessing you did but I don't remember seeing any pictures of the inside of your boat.
