Telemetry
The graph below is from a Spektrum DX6 transmitter + UMX Night Vapor plane + Spektrum Telemetry Log Viewer software (http://www.tlmviewer.com, free, running on a Windows 10 PC). It shows a 7-minute indoor flight at the HUB Sports Center Saturday 1/29 4-7 pm. I thought it was interesting, even if not that useful for flying there. Five things are graphed, each with a different color, after software filtering to smooth out the lines. I am curious if other club members have actually made good use of data like this.
* ESC Voltage (light blue) and Receiver Voltage (yellow) track each other and show an initial full-throttle take-off dip, drain during flying, and recovery after landing.
* Holds (dark blue, received signal loss for about 1 second) stays at 0.
* Frame Loss (green, received signal fades) climbs from 90 to 350 during the flight. I don't know why it starts at 90 and not 0. From what I read less than 20 per flight is good, so this looks very bad. It seems odd to me that it climbs so steadily instead of being a rare event. So I am questioning its accuracy.
* A Level (red, received radio signal strength) changes per loop around the HUB basketball courts. You can see during the full-throttle take off that I was making a few close tight loops instead of going all the way around the courts like the rest of the graph.
