9XL & Mamba Max Shut down!

[glassdoctor]

You can hardwire the fans... to the esc's main power leads from the battery if the fans are 12v, or to the output leads from the ubec that go to the rx if the fans are 5v.

The ubec is easy to wire up... it will have two input wires that go to the battery and two output wires that go to power the rx. You will have to hardwire or make a connector to hook up the input leads. And you might even have to put a rx connector plug on it to plug into the rx...
