I guess the bottom line is this......
If you want an easy setup and a great heli, the HDE is the way to go.
Well said.
I'd also like to add that somehow I got turned around while flying my Rex on Sunday. I was flying inverted and had been for a few minutes. Then all of a sudden it was upright, still not quite sure how that happened. Anyway Being upright with negative pitch and only about 10 feet from the top of a shed heading down fast, really fast I slammed the collective stick to full positive pitch and the heli just suddered a bit and went up. I was within 3' of the shed when it started back up. This was with my HDE Rex running DS281 servos. So I think the servos are plenty strong and the single servo doesn't seem to be an issue. I mean how much more violent a manuever are most of us gonna do.
