Oh, yes. Strictly on the range basis, with a DX6i, at about four-to-five hundred feet out (horizontally) I've ended up intentionally grounding the bird as gently as I can to keep from losing it. (yeah, I meant to let her get out that far). Eyeballin' it I'd say about 3 hundred feet distance (out plus up combo) is the maximum distance you'd safely fly these babies without losing visual orientation of them, for a relaxing flight of just cruising and enjoying it without constant control input. But I've read the range is +- 1000 feet on the receiver's end (somewhere I cannot recall--correct me if that's inaccurate) and that's with strong batteries on both ends, of course. Our vision is the definate limiter here, unless you've got FPV and are "in the seat" virtually
