I’m wondering if anyone has attempted to upgrade an A1 stick grip to the C1 style with built in trim switch? From what I can tell the only difference is 2 relays and the stick grip. I believe the grip is nearly identical other than the top switch.
Diamond has a service bulletin for the early C1’s built with the center trim switch to covert to the later stick mounted trim switch.
Since the SB is for a C1 how would I get the work signed off?
C1 stick grip for an A1?
