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.

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