You CAN NOT just buy the A11 piece.

You CAN strip off anodizing, mine started out blue, but finished chrome I just used some wet and dry (1200 grit sand paper) to get it off, then used some aluminium polish to make it look sexy.

I actually don't use the huge piece of plastic that mounts the servo. I just use normal servo mounts, and I am going to run my reciever onto top in the carbon upper brace when I get it. Well that is what most people do with their TT-01's.
