Ok, I finally got to try my tests. Bear in mind though my second esc uses an external BEC which I think may be why that one doesn't fail at all.

1. Rebind SR3500 to MM ESC where the problem is occurring.

NO CHANGE

2. Connect SR3500 to other MM ESC that works fine with SR3000 receiver

It worked fine


3. Connect the new MM ESC I have that shows the issue to the SR3000 reciever and test

The problem showed up


4. Put fresh batteries in the transmitter and see if that helps

NO CHANGE

5. Check connectors on new MM ESC and see if there is an issue (your buddy had poor solder joints for the motor wires, maybe that is part of it for the deans plug?)

Connectors appeared to be fine


So, and this was posted on another thread but I gave it a try prior, looking at how it was just ticking away, I decide to do the setup process to see if that was what it was waiting for. Once I did this, it worked fine. Each receiver booted up, and even would boot at 1 sec interval or 5 sec. Didn't matter. What I am curious about though is that it was said that if you change settings, you need to reconfigure the ESC. I went back and changed a few things, but it still booted up fine. So I am not sure why it needed to be reconfigured then. Seems like it just forgot a setting.

But it works fine now.
