Huison,

Not sure why you are wanting to use the 1.56 version on your ESC. One thing that I have read somewhere is that once you load the newer versions that you cannot go back and load the older versions like you want. Which version did yours come with? If you just recently bought it, it should have a fairly new version installed already. Also, with the newer versions you have a lot more features that you can program, including percentage braking, more options for outrunners, etc. If you have the right controller that is. Just an FYI...
