Hi, when you first switch on Tx first thenRx you should see red and green flashing leds this is set up mode. put Tx stick in middle of travel then switch on as Rx lights flash, press set up button [ bottom right ]lights will change push stick all the way forward then slowly all the way back to other end of movement [ full astern ] then return to neutral when solid red and green lights should appear this is neutral no sound , just silence and red and green light, took me a couple of try's to get it right. Switch of Rx first then Tx . when switching on next time Tx first then Rx WAIT for lights to stop flashing on ESC thereby using saved settings, hope this helps.

Please tell us what Transmitter and receiver you are using? A picture would be useful.

The issue with whining motors is directly linked to the operting frequency of the electronic speed control. Low frequency controls produce much more whining than high frequency controls. I do not have any experience with Minitronics that I found encouraging, ie, I do not use them anymore. Some folks say to simply put a louder sound system in the boat or operate it further from shore. I prefer a more poitive approach and use a german controller that is totally silent. They are expensive, but very reliable, I have them in seven ships and they perform flawlessly.
Most of them are LIPO compatable, but can be used with other battery sources without issues.

Instruction to set up esc.

thanks for the reply, but that doesn't work!

could you tell me what the rosary knobs at the top of my transmitter marked Lum and Bac are?

Thanks

Hi Hillro!
I agree with you that the fine tuning is wrong. . . 👍👍👍

Thanks for your reply, the esc is a mtronics viper marine 20...how would I tune it?

You have not said what manufacturer is the esc. It sound to me that you need to tune either the esc or the zero point on your transmitter. The noise indicate that the esc is not quite at zero speed.
