One battery at the summit

What better way to maiden a new quadcopter than to bring it on top of a mountain and send it into the void? To be fair, I had done one flight before, just to make sure everything was working perfectly. That HelioRC Spring flight controller is really something! Without any tuning, I get already some very good flight performance out of a totally new build, with 6 and 7" propellers that is! If you've ever built a 7", you know how hard it can be to get rid of nasty vibrations. I noticed some low-throttle growly oscillations that I can apparently tune out by increasing the Q value of the imuf (gyro) filter in Butterflight. We'll see! Some mid-throttle jello is still present but it's quite minimal and I think I can make it better with some MoonGel.
