Thanks, and yes the sound is nice now.
If I'm picky maybe the PIDtune/sound could be even better, but it's not far off from how it is tuned now.
Should stay a bit higher for trying new tricks, but overall I rather not go too high.
It is easy to drift away from the location where I'm standing, very hard to tell when not seeing the ground or not hearing the quad.
Also yesterday there was a helicopter flying around in the area, so had to stay a bit low anyway.
