Both subjects were suggested in comments to prior videos.
First, we look at changing the Safe/AS3X switch on current EFlite UMX models. It's a quick change. Without Forward Programming you cannot turn AS3X off with Safe enabled, even on a 3way switch. Also, a look at UMX ESC Telemetry.
Then we go over setting up Safe/AS3X/No Gyros again. This time instead of an aircraft I'll use a test bed built out of salvaged parts. I also changed the NX8 display to get more contrast and readability.
