| Mamba X 3800 issue
I have a trx4 that I installed a Mamba X 3800 “Crawler Edition” combo. It’s been ran 3-4 times and worked excellent. No problems at all. Today I went to program it with the B-Link and it gives me 2short beeps and one long beep. It not hot since it hasn’t been ran in a few days and my condo is kept pretty cool. I’ve tried using b-link to reset programming and are sure the thermo shut down is off (default setting). What am I doing wrong here? |

2 short beeps followed by a long beep (along with all ESC lights flashing) indicates the ESC is not getting a radio signal from the receiver. Double check the ESC is plugged into the receiver correctly and the receiver is getting power. Even the most experienced among us is not above plugging in a receiver plug the wrong way from time to time. |

Also I’m an idiot and read the guide as - - • being short short long instead of long long short. You guys are probably right and I didn’t plug something in correctly. Hoping I can get it going when I get home. Thanks for the quick responses. I’ll update tonight. |

Ended up being the receiver. Pulled the traxxas receiver and put in a futuba system I had and it works perfectly fine.
