Help we are newbies to all of this.

My son bought a voltenex catermeran and we are trying to install a new dynamite 90 amp esc. Did not come with instructions. We found some online for the 120 amp and followed those. But not working.

Here is what we are doing:

Turn radio on and pull throttle to full forward postion
Next we connect battery and then turn on esc
It then makes constant beeps and shows a green light on esc. While doing this the motor is glittering.
We then try putting in neutral but still nothing changes.

What can or do we do next?

I have attached a pic. I have a video here on YouTube

Also Note: The ESC has an on off with and another button that says SET. Not sure what SET button does or how it plays a part in all of this.
