Hi Guys,

I have a Futaba 9 Super PCM that will guide my latest plane. I've going to have all my channels filled up, but I want to use 2 separate batteries.
I heard that a battery lead can be spliced into a non-vital servo (brakes) going into the RX, How can this be done with a Futaba servo?


Here's my layout:

1- aileron
2- elev
3- throt
4- rudd
5- gear
6- flap
7- brake valve --(and spliced to batt 2)
8- steering (nose)
9-aux (2nd throttle lead)
DSC- batt 1

Thanks in advance for any advice or your experience,
Mike T

Just use a Y-cable into any channel you like. Be sure to use seperate switches for each battery.

The 2nd battery 'y'd with a servo straight to the rx won't hurt the servo?

A common use of dual batteries is to isolate the retract servo (or servos) with a separate battery on a larger plane with mechanical retracts, that way if a retract jams and drains the pack its not taking the flight pack battery down with it.

Other than that, once the power hits the reciever its distributed over a bus, meaning all the positive and ground pins on the reciever and servos are seeing the same voltage.
