So we just completed the install of a 430w, BT audio panel, ads-b transponder and G5 hsi. We plan on ditching the vacuum system but are torn on which way to go with it. We are wanting to use this as our IR trainer. As of now I think our AI is slowly on its way out and our TC will be needing some attention as well. My question is what are some of our options to replace both the AI and TC? Our current plan would be to O/H the TC and replace the AI with another G5. Are there any other options that we may have to go all solid state?
