Kraton Noob question - SR315 receiver

[SaltyLocal]

My apologies for such a newbie question but can some please explain where the ESC, Servo, etc plug into the Spektrum SR315 receiver? I’m not seeing any meanings for the receivers abbreviations: STR, THR, Aux, Batt. I should took a picture prior to disassembling the entire Kraton 6s v5.

Channel 1 for steering servo, channel 2 for esc. Easy way to remember- 1 to turn, 2 to burn

Thank you @joshludden ! Happy New Year!

How about Batt? Secondary battery?

Happy to be of service!Happy new years to you as well

What do you mean? Wouldn't those just connect to the thick ESC leads? I'm assuming you are referring to 3S battery "A" and 3S battery "B"?

I’m referring to the abbreviations on the SR315 receiver seen below.

Oh, I see, sorry. I don't have one of these, so can't just provide a picture of mine or anything, sorry. It's a bit disappointing that the receiver manual doesn't define the different plugs:

How many servo-type cables come off your ESC? If it's just 1, then that would be the throttle-input-signal cable. But the ESC typically also serves the function of a BEC (Battery Eliminator Circuit), taking the main battery voltage, and reducing it down to something for the receiver and servos (6V, 7.4V, etc).

So that throttle signal cable might also provide power to the receiver. If there's just 1 cable from the ESC, plug that one into THR, with the steering servo plugged into STR. Put the car up on blocks to get the wheels off the ground, or remove the wheels, for safety. Leave AUX1 and BATT empty for now. Power up the ESC with the main battery(ies), and see what happens.

I'm guessing that BATT is used if your ESC does not have a BEC function. And instead, you are powering the receiver and servos using a separate small 2S LiPo, or with a separate BEC (not integrated with the ESC).

If your ESC has a second output cable (possible with just 2 wires, instead of 3) that could be a BEC-power-output cable, and it would presumably go to Batt. But it might be OK even without connecting this hypothetical second cable.

I don't think the AUX1 connection would typically be required with most cars. Again, sorry, I wish I could offer concrete details from a Kraton of my own.
