Is your feature request related to a problem? Please describe.
the power distribution on the FC for 3.3V, 5V and 10V is crucial as of potential brown-out problems.

Describe the solution you'd like

• 3.3V MCU: feed MCU with safe-guarded 3.3V, eg. direct conversion from bat to 3.3V via dedicated BEC
• 3.3V sensors: separate 3.3V for sensors, ext. components
• 5V Vx: dedicated BEC to provide high-current servo power
• 10V VTX: VTX power delivery needed ????

Describe alternatives you've considered
Alternative:
cascaded step-down Vbat --> BEC (5V) --> LDO (3.3V)
