Assuming.... 1, Your BEC is only powering two servos and not the receiver. ESC powers receiver. 2, Both Servos are fed from the same signal, ie...like used in a Traxxas duel Steering servo set and not independent channels. You didn't specify. |

Yes the BEC will only be powering the servos...i have a Redcat RS10...i saw a different diagram that shows each servos white wire independently still plugged into the receiver, both red power wires connected to the power wire on the BEC and both black grounds connected to the grind wire on BEC

you can use one bec for the two servos even though they are different channels as in the 4ws of the rs10. be sure to run signal and ground from each servo to the receiver and power lead and ground to the bec from each servo as well. the only reason not to also use the bec for the receiver is if you have set the voltage up higher than what the receiver can handle (over 6 volts in most cases) the quality servos can handle 7 and even 7.5 volts. try to find the specs for the servos you will use though 6 or even 6.5 volts should not be a problem Last edited by cabron; 01-05-2015 at 10:21 PM. |

The D772 running on 7.4v. stalls at 2.86A, so you're good to go.

Use a cc bec to power them. You program the bec's output to 7.4v. Just follow the diagram above.

According to the diagram above i splice together the yellow servo wires and plug into the receiver..I've also seen a diagram with each servos yellow wire plugged into the receiver independently (not spliced together) with only the servos red wires spliced together and the black wires spliced together...on a RS10 wich way should the yellow wires be plugged in?...stock configuration has each servo plugged into the receiver separately.
