There is a couple of options though. The below listed suggestions is if you use a Castle Creations BEC. The reason why I have chosen that BEC over others is it's fully programmable with the Castle Link.

1. If you want to use the full potential of the SI-4431 and you don't use the logging feature in your RX8 Gen2 ESC you could use a BEC and hok it up to the receiver, doing so means you will have to unplug the + (red) pin in the connector from the ESC




2. If you want to keep the logging feature on your RX8 Gen2 ESC You can do pretty much the same as above but instead of connecting the BEC to the receiver you can connect it directly to the servo but where you connect the signal wire from the servo to the receiver.
