Hi Dave:

It's the Son of the Daddy of back up units but not the Daddy itself......I have the Emcotec DPSI Twin in my UB....it's been around for more than a year....dual batts, dual RX, line isolators and amplifiers, failsafe master switch, etc.....8 channels for servo control and uses 1 channel for failsafe detection and RX switching......can control up to 25 servos......

The more channels you have to route direct to the RX, the more chance you have of introducing interference....

I wish both Emcotec and Duralite would come out with 12 channel units thru the box....
