Hooking up 2 BEC without going thru RX

[rcs2022]

The second diagram was a test if i needed to hookup 2 BEC's; not for power but to have 6v and 7.2 v respectively for the throttle and Steering servo. I can run (which just finished hooking up on one 6v bec) both servos on 6V which would be sufficient and ok. The servo i have switched to is the HK15298B; 18kg-cm on 6v and 20kg-cm on 7.4v; a 18kg-cm is already a substantial increase over the 12kg-cm of the SF-50 stock Savage Flux servo. Or i might have to find myself a decent and cheap 7.4 v for the throttle.

Got the HK to see if 120 or 150 usd for a higher torque servo like one of these have my eye on:
Hitec HS-7955TG or Hitec HS-7950TH

Probably then would stick to the 7955 as it is max rated at 6v.
