For a stable output voltage, the BEC should be set to at least 1.5v lower than the lowest supply voltage. Setting the BEC for 7.4v on 2s will cause the actual BEC voltage to be around 1v lower than the battery voltage and it will fluctuate as battery voltage dips and rises with the load. The servo may be able to handle this ok, but the receiver may have problems with the fluctuating voltage.

I would set it for 6v max for best results.
