I setup my new 766 (766 main, 116 tail and 25T tail pinion) for 1400/1650/1750 head-speeds in normal/idle-up1/idle-up2 modes. But right now I am a sport/beginner flyer still working-up to inverted flight. That being said, I love lazy circuits, figure-8's, and trying to follow my fixed-wing buddies. So... my question is should I consider a lower head-speed for gentle flying around? And if I go lower... how low is "safe"? I read other forums where people push 750mm blades as low as 800rpm. What does everything think?
