Pre-takeoff checklist
I am looking to purchase maybe something like an Archer II. If I found one with an autopilot unit that needed to be replaced, is that prohibitively expensive? It would be one with the same number of axis controls, so I wouldn't necessarily need to have the airframe (wing or empennage) opened up, right? I would think that if the servos & linkages were okay, an A&P would just need to switch the control unit in the cockpit, but I'm not sure. Approximately how much would something like this run?
