I have been using Castle since I started electric. This year I got an OS 110HV for my 2M and LOVE IT. Very easy to use, very smooth, quiet, and cool, and the brake actually WORKS.

I am flying the Plettenberg Advance which I think is 20 poles? I would have to double-check that. But I set the thing up once, looked at the instructions once, and have been using it flawlessly since the first flight. I love it.

I suggest getting the field programmer. I am thinking about selling all my CC and getting more OS.
