| Why only 1 BEC?
Noobie question... Why is it that when you run an external BEC (or 2 ESC for Dual motors) that one ESC BEC has to be disabled? Wouldn't the 2 BECs working together provide MORE power?

Generally, only the steering servo runs off the BEC. If you are running 2 steering servos for 4ws, you'd want either 2 10 Amp BEC's or 1 Castle Pro 20 Amp BEC. |

Also, the esc bec and a CC bec are generally providing different voltages. One will fry the other if the red wire isn't pulled.

Also people usually run higher volts to their servo but the radio usually can't handle higher voltages reliably. So maybe 6+ to servo, while the radio gets 4.8V usually.
