1080 ESC Calibtration Problem

[Matt0676]

Hello everyone!

I am having some serious problems calibrating my 1080 ESC. Let me add that I have watched a ton of videos and read other threads...I feel as though I have a very good understanding of the process and how it is supposed to work.

Here is the rundown...when I turn on the ESC and enter calibrate mode, all is well. However, when I try that first calibration (neutral), it doesn't beep and just turns the LED off completely. I have steering, I have LEDs, I have no throttle.

When I just turn it on normally as though I'm going to crawl, I get 3 beeps (running 3s battery), but no single follow-up beep to signal "ready". It instead blinks constantly with no end in sight.

Here is a list of the troubleshooting steps I have tried:
- Factory reset ESC
- Factory reset ESC with programming card
- Re-bound my Tx and Rx a dozen times
- Quadruple checked that both my Trim and Fine trim are at 0
- Disconnected my servo, keeping only the ESC wired to the Rx
- Swapped batteries
- Checked motor wires and flip-flopped them
- Tried the 3-prong wire from ESC to Rx in both directions

Here is a list of the components I have:
Transmitter - Spektrum DX5C
Receiver - SR6100AT
ESC - Hobbywing 1080
Motor - Holmes Hobbies CrawlMaster 16T
Batteries - 3S 3500mAh
Servo - Savox SA-1230SG

Any help you can provide is greatly appreciated. I am 90% done with my first build and am dying to crawl! The sad part is, our local hobby shop is closed for 2 weeks due to COVID.
