ALIGN Control Link - Trex 550 Series / Trex 600 Series

I bought these as spares for my 550 DFC, and mostly for the small screws. The top pic makes it appear that they are steel, but they're brass and can be damaged easily (my installed originals are a little chewed up). It's important to use a correct fitting Phillips bit when installing so that doesn't happen. These tail links are used on a lot of the large Align tail rotors, including the 800.
