preparing to install an autopilot in my -4 and looking for help on hardware. the plan is to stay all Dynon as it already has a D180 in the panel. Most of the posts on the topic in the forum are fairly old and hoping to get some current advice. looks like everything is readily available with the exception of the roll servo hardware. I'd like to install it in the cockpit as this seems like the easier option with the wingtip being riveted on. Does anyone offer the roll servo hardware that includes the clamp for the torque tube ? Didn't see it on any of the websites including Dynon, Trutrak or Stein.
another question is would you install the AP74 or just utilize the autopilot in the D180 ?
