Sounds like you have power to spare, I bet she rises fast at full power!
I'm not sure if that's an ABC whine I hear or not, I am a little hard of hearing at the higher pitches. With some of my recent aircraft I've found myself choosing between the lighter but less efficient 2211 rewind, which is ABC only, and the 2730 dLRK rewind. Between those two the dLRK wind is definitely quieter and a more efficient for an extra 5-10 grams or so. That ABC whine really stands out between these motors, and that's what I think I'm hearing in your video.
Which wind did you use on those 2730's?
