sabertooth controller on eagle dozer problems

[Yard Toad]

Ariari not sure if your dozer came with a stand alone ubec rated for 5v-6v 3amp. It’s the one with the wires that are wrapped around the green ferrite ring. My came stock it is what I use to power receiver and all upgrade digital servos. Disconnect the pump and motors red wire at the Servo plugs going into the receiver. Plug in the ubec into the receiver ( Servo plug only has two wires red black). This will power everything.

The specs for the Sabertooth show that the bec only puts out one amp.
