Traxxas 1/16 erevo vxl Bluetooth link update failure and fix.

The Bluetooth link update failed in the app when it got to the receiver and the car would not communicate with the controller. There was no throttle or steering control. The green light would flash rapidly on both the receiver and the speed controller. And occasionally it just flashed red on the receiver but still got no control over the car. Ultimately I turned the car upside down and retried the update through the app. It completed the update and everything worked. So if your car fails the update don't go replacing speed controllers and receivers just try turning the car upside down and redoing the link update through the app. it worked for the 1/16 E-Revo.
