I am selling my F550 with 3mm Carbon arm extensions (I bought the extensions from a member here on this board), along with a set of plastic gear. I drilled the lower plate to mount my PS1 mkTR Pro and sanded back the copper so it wouldn't short out when I put screws through it. Never actually flew the hex, I took it apart and used the equipment to build a y6 instead.
