Hi,

I am completing assembly of my Align T-Rex 700X Super Combo which comes with Align 850MX motor, Align rebranded Hobbywing 120A ESC with built in BEC, Microbeast PLUS FBL. I am using a Futaba R7008SB setup in a standard configuration, non SBus. My batteries are two LiPo 6S 22.2V 5000 mAh 60C connected in Series for 12S. I have already bench tested this setup successfully just to confirm everything works and it does. For convenience and safety reasons, during servo installation and FBL programming, I used a LiPo 2S 7.4V 2200 mAh battery plugged into the R7008 SB battery channel.

Prior to this build, my experience in electric helis have been limited to 500 size. This is my first 700 and I wish to set it up with the separate battery for the receiver and servos. I woul like to solicit the help of the forum members to make this possible.

Thank you!

Just disconnect the hot wire from the throttle servo wire. Just lift the tab and fold it back along itself. That will disconnect the bec. then you'll be able to use a 2S batt direct to your rx if it can handle that or you'd have to use a bec to bring the voltage down to where you need it to be.
