Some times the worst case scenario is not figured in to the design. Meaning it all works fine until you add some other goodies on like FPV camera and transmitter, the system gets over loaded. The BEC being the heart of the system supplying power has to be rated for the absolute worst case current draw.

If you can replace that as a separate module, I would suggest getting one that is rated to supply a much higher current. Your system will only draw what it needs to run but if it needs more current to stay running, it's nice to have it on tap. Other wise the BEC gets flogged and fries.
