Hi all,
Currently waiting for my copterx to arrive and looking forward to setting it up. I've read a number of posts about what parts to buy but would love some more advice on the following points:
1. What motor? Thinking about a scorpion but not sure which best suits the cx.
2. What esc? Same as above?
3. What cyclic servos? Use SG90's on my HBK2, are these good enough?
4. What tail servo? Use a hitec hg50 on the king but wouldn't mind getting a digital one to increase the response speed with HH gyro, any suggestions?
5. What HH gyro? I use a skya lx303 which I think is the same as a G401B, again wouldn't mind advice on a better one.
6. Batteries? I use 2200mah, 15C, will they work?
7. Replacing screw set, does anyone know where to get the sets?
8. I have a spare Spektrum receiver that I got free, it's an AR6100 which is compatible with my DX6i but quite a basic model, will it do the job?
9. Where do people get spare blades from? I normally get woodies off the bay from HK but I'm not convinced on their quality due to ongoing tracking issues.
10. Any other spares or things I've forgotten?

Sorry that I have so many questions but I'm keen to get the setup right from the outset, it all gets so expensive.
Many thanks in advance.
