My second pack ever on the new Leader 3s (turnigy nanotech 3s 450mah). Sorry about the flying, yaw rate is a little different to my usual. Very smooth on 3s, stock tune is tight with very little prop wash. Speed is comparable to babyhawk r 3 inch, maybe a fraction faster. You probably can't tell from the DVR but the video feed is exceptionally clean.
