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.

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.

Make sure your Sabertooth's dip switches are in the default positions, as shown in Figure 5. It would be a good idea to read the Sabertooth manual to familiarize yourself with the different settings. With the default settings, you can now control the rover although the controls will be reversed. This will be corrected later.

Step 7. (Optional Pan and Tilt)

Create a pan and tilt. Detailed instructions can be found here. Insert the bottom servo into the top panel and secure with 3mm hardware.

Step 8.

To set the controls to behave normally, you must adjust the servo option switches. They are located on the front of the remote. Set them as listed in Table 8.
