You might need to ask these questions in the Walkera sub-forum section.
I don't know how many Walkera people would look here in the general section.
Most of them would probably not look at the "Impulse Buy..." title you used.
There are a number of other sources for parts. I did a Google search for "Walkera 5G6" and came up with some hits that are worth checking out.
RC Fever and some others had some parts. Plus someone was selling parts on ebay as well.
