Well that was probably the best RC video I've seen posted on RCU, or anywhere else for that matter. Truely awesome job! High quality, well correographed, great music & awesome flying! Get enough guys to watch this video and you'll have the next Zagi on your hands! Can I ask a aquestion? I'm purely a hobbiest when it comes to aerodynamics, but how do you calculate the torque roll rate / what factors impact it?
