Took the X50b and the LE600 out yesterday. Wind was variable 10mph gusting over 20. The X50 flew great, was able to do some slow pirouettes, attempt some funnels, and do some inverted hovering. Still getting used to the feel of it, but I'm really starting to like the way it handles. The 600 on the other hand, was bobbing up and down, side to side and the tail was all over the place. Thought I finally had the 3G dialed in... guess not.
