Spirit System

Plan to connect Spirit to AR7700 by SRXL mode.
According to the manual, RUD--> AR7700, AUX---> ESC, so where to plug the BEC?
For my current Heli, I do need extra BEC connect.
I know change to Pro will fix it, but any solution with Spirit?

Hello,

you can simply put it in the receiver to the THRO port.
