Receiver model: futaba FP-R102GR
ESC This has no bec
Servo works on that channel and so do other speed controllers.
Not checked with multimeter.
The boat is a fast sports cruiser and so the batteries a run together to give 14.4v. Because of this layout both batteries need to be plugged in to complete the circuit.
The fuse you see in the picture is a 30 A and it has not blown. lastly none of the setting were changed from the last outing.
Receiver is OK for that ESC
Servo working means you get full sweep on that channel. OK
There is a 5 position rotary throttle setting 25%-125%,and a 3 position frequency setting.
You could turn the throttle selecter back and forth to clean it in case the contacts cause a 25% reading.
The higher frequency 2kHz setting will make the ESC less prone to cutout from the motor stall current at startup.
Switch off/on the 4.8 volts after changing the settings.
Don't jump to conclusions if you have the same set up as before.Try a
bulb instead of motor or
reduce the voltage to see if the stall current is triggering an overcurrent trip.
