I think the A56 part is a typo. The A50 is very popular for the Wind 110. Another option if you want to go cheaper and want to get started is the Wind S 50e. I have one and I really flies nice. Not a lot smaller than the 110, but flies very nice as well. The Wind 110 is its own design, it is not a scaled down Wind S pro, whereas the 50e is a scaled down Wind S Pro and flies very nice. You can run the smaller and cheaper setup with the A50, 16S, and a 6S setup and it is a rocket ship if you want it to be. I have one and on a calm day it flies very similar to my 2m version. The Wind 110 is very nice also, but just more expensive. It is a little larger and heavier, so it does handle winds a little better. I don't think you can go wrong with either setup.
