Step 1.

The Sabertooth 2X10 RC has a feature called battery elimination circuit (BEC) that provides power to the RC receiver. It can provide enough current to power the receiver alone, but not if servos are used. In order to provide enough power for the receiver and the servos attached to it, we need to add a separate battery pack. In addition, we need to bypass the Sabertooth's BEC to prevent it from interfering with the battery pack.

Use an exacto knife to carefully pry the black tab up and slip the red wire out of the black housing as shown in Figure 1.

Bend the red wires up and use electrical tape to cover them as shown. This will prevent accidental shorts.

Step 2.

Plug the Sabertooth into the receiver as shown. Make sure the yellow wires are toward the middle of the receiver. On some versions, there are two connections marked "AILE". Use the slot between THRO and ELEV for CH 1.
