Hi EMWIN,
I am also installing my CAPX with a Saito FA220a. I'm going to use the supplied motor mount, eventhouh in the instructions it is installed with a 180. I'll remove the predilled holes in the firewall by filling in it with 15 minutes epoxy, and redrill new holes so the FA200A is wider than FA180 & 150.
I have doubts about if the supplied motor mount will be strong enough to support the 220. I hope so
Regards,
