It would limit travel available overall though right? Hard stops on the servo
Yep. Good call.

You should be using the capstan style of servo for full travel. Mount it aft of the baggage area.No dice on the full travel. it’s too bad would have been a great location, concealed and easy to access inspect/adjust. Im going to try making a longer arm but im not optimistic, it’s a long swing to cover the elevator travel. maybe someone else smarter than me has a hack to make the arm work vs the pulley?
Yea, Have a few friends with the Garmin stuff in a 182 and a Bonanza. I bet there are some Garmin software engineers working overtime. Engaging the autopilot at 2-300 feet in a Bonanza and getting a runaway trim could be disastrous.Only applies if optional auto trim is installed. I don't know how common that option is but it's not used by CubCrafters.
With the basic pitch and roll servos the Garmin system gives a "trim up" or "trim down" alert when the pitch servo is holding torque against an out of trim condition. The proper response is often a change of thrust rather than a change of trim.
I don’t know of anyone running a jackscrew trim with their autopilot.
Main issue I could see would be with the Bonanza where the trim can over power the elevator. I know a guy who did not set the trim on a Bonanza correctly for take off and dam near killed him. My wife and I forgot to set the trim on our 182A once for take off while doing touch and goes, it was very heavy it pitch till I got it trimmed. That was my concern. On a Cub I don't think it would be hard to over power and turn off if the stab trim was rigged up.Trim tabs are pretty simple to overpower for the duration a guy would need to hit the disconnect button. I don’t know of anyone running a jackscrew trim with their autopilot. I’d suggest a Safety Trim controller for anyone with electric trim on a trimming horizontal.
I sorta wish I had the 305 or 507 controller. The AP would be more functional. No plans to upgrade mine. It does enough as it is.
Another vote for the 507 controller if you’re using a GFC500. While the G3X interface works, if you use it much my opinion is a stand alone controller is really helpful. I like knobs and I’ve spent quite a bit of time “dialing-direction” through heavy traffic areas.
The first two pics I took at Jay's shop. This first one shows the under-seat aileron mount (that is Jay's airplane that is shop) - I could not make this work with my large Dynon servo. But you can kind of see how the parts would go.I know this is an old thread but maybe someone can help. Javron Super Cub wide body. Got the autopilot brackets from Jaye. Been scratching my head figuring out how these go. Anybody got any ideas? Thanks
Thanks so much for the reply. This helps alot.The first two pics I took at Jay's shop. This first one shows the under-seat aileron mount (that is Jay's airplane that is shop) - I could not make this work with my large Dynon servo. But you can kind of see how the parts would go.

This next one is what goes under the rear baggage. All I got was the big tray (black in this pic) and I will have to custom-make the part to hold the actual servo up - again my Dynon servo is way longer but should not be an issue for the elevator one. That tray then goes on those tabs they probably already welded on the fuselage - I have not installed the elevator one yet so not much more help.

Then below is what I had to do under my seat for the Dynon servo - made a custom bracket out of steel that spans the seat frame and then there is a third attach point welded to the seat tube (bottom of second pic below can see it better).

EDIT: I have the same - widebody Javron.
Is that the GFC500 and is your cub experimental?Yes. My G3X Touch drives a 2-axis AP. I can think of a few other members here who have the same.
I use to feel that way but after flying my Super Cub two hard days to get to Idaho it is kinda nice to travel in an airplane that is comfortable, capable of playing and I am not worn out when I get there. Too bad I can't afford one. I guess this is why so many of our friends have bought Cessna 180s.All you need to ad is a reclining seat and a seat shaker to let you know when you get there
