Hi all,

I've been playing around with my Ez-B 4 controller and loving every minute learning about its features.

The robot I intend to install it into is a Lynxmotion Johnny 5 tracked robot, with minor modifications (the original SSC-32 servo controller has been removed). I've become really confused on how to set up the Sabertooth 2x5 R/C motor controller however on the EZ-B.

The Sabertooth is the R/C model with three separate servo wires for FWD CH1/FLIP/TURN CH2, set to independent control, connected to a 3800mAh 11.1V Lipo battery. As per the SSC-32 setup, I have disabled the battery elimination circuit (BEC) by removing the centre red pin of the CH1 and CH2 channel (scrolll down 3/4 of the install guide below for this):

The Ez-B 4 is connected to a 7.4V Lipo battery

The problem ...

• When I plug in the 2x5 CH1 and CH2 servo wires into the EZ-B controller, it powers up the EZ-B! I thought I'd disabled the BEC, and am concerned about 11.1V frying my servos (Hitec 645-MG)

• Can I run the 2x5 off the 11.1V Lipo, and the EZ-B off the 7.4V Lipo (to run the ~ 14 or so 645-MG servos)? The reason I want the 2x5 running off 11.1V is for faster motor speeds (this robot will be used in gait analysis, tracking people's movements).

• Is there another controller that will make things easier - noting I've potentially the wrong Sabertooth (R/C model)?

Thanks in advance - I know I've missed something simple, hopefully ...
