Hi everyone, 

I want to transform my old RC car, i have the APM and everything that i need to transform, but i have some doubts about how to power it.

First of all my ESC is a Hobbywing xerun 120A : http://www.hobbywing.com/goods.php?id=350
And im using a lipo 2S, and i will use one servo.

I've thinking about 2 ways.

1.-  Keep the JP1 connected and don't use the power module
2.- Use the power module and take off the red wire of the ESC ( or remove the JP1 and connect the red wire )

Which one should be better? Any recommendations or tips?

Thank you so much
