I posted several weeks ago about diagnosing an ESC issue after a crash I had. I eventually came to the conclusion that it was indeed an ESC error and I eventually found a new main board in South Africa that I had couriered to me in Swaziland. I have replaced the main board and actually installed 3 new motors at the same time. Now everything "seems" to be working correctly except I can't get the initial startup "beeping" to stop and the motors never turn, even on startup like they normally did. Any ideas on what the issue could be? All the LEDs work fine, the camera works, and the GPS locks in fine. I even get the front solid red LEDs and the flashing green LEDs in the back - which I believe it the right status that everything is okay. The status on my iPhone says everything is good and ready to go. I originally tried it with the old firmware and then upgraded to the new firmware. The update went fine and all indicators say I'm upgraded. I've double-checked my solder joints and they all seem good as well. Thoughts?
