There is an application called RPM Gauge for audio taching by android phones. I ran your vid on my phone on a split screen with RPM on the other half of the screen, measuring the engine speed by the sound it emits. I made a screenshot on the split screen and that was it.

Oh, okay! I'll see if I can find it and give it a try.

Laughing Laughing  Yeah, you're probably right!!  But man, it was fun!  I still haven't figured out what we were doing wrong with the tether  Huh...  Huh...   I tried just spinning it around me without the engine running, gradually letting out more and more line to the 15 foot limit and it seemed to be balanced just right.  The spin test can be seen here: https://youtu.be/44Em1XJpM7c.  However, under power it just didn't get off the ground as I've watched in other tethered flights on You Tube.

In my heart, I would have loved to try it on the free flight but I just didn't want to have to climb no tall pines so that would have to wait for a nice calm morning.  And it was just too windy to try it on control lines even the 20 footers.  Heck, if the "big boys won't risk their 35's and 40's, I'm sure not going to risk an engine that doesn't belong to me Doh! !! Laughing Laughing   Nevertheless I am so grateful for the opportunity  Clapping  Clapping
