Default autopilot add-on

Has anyone added a 2 axis autopilot after the -3 was built?
Just wondering how difficult this might be ??

Not too bad. The wing mounts are retrofittable and so are the fuselage ones.

You're welcome to stop by and see the fuselage pitch servo mount. The wings are out at the Longmont hangar so that's where you'd see that.

Email sent.

I'm hoping to add a 2-axis Garmin autopilot to my new-to-me RV-3 at some point in the future. I had hoped to do it this winter, but I've got too many non-aviation obligations pulling at my time.

I'll probably do as much planning and research as I can between now and this time next year in hopes of pulling the trigger next winter season. If you'd like, we can provide updates via this thread so everyone benefits from the research.

I'm tempted to order a few Garmin brackets and a servo or two. I don't think there's any reason I can't install the servos before the rest of the G3x system is ready for installation.

What type (brand) of autopilot and servos are you considering?

For Garmin, look up Ironflight's postings in this section. They installed one in their 3B as he built it.

Hi Mike,

Thanks a ton for posting those pictures. I’ve downloaded them and I’m sure they’ll be very useful when I install my Garmin servos.

Did you fabricate custom brackets, or are this Garmin stock parts. I’ve heard of some using the RV4 brackets for the pitch servo and I don’t know what they’re using for the roll.

Mines a non-B wing spar, so I’m not sure how that’ll change things.

Hi Rod. I used the RV7 mounts modified a little for the wing and the RV8 mounts again modified just abit for the pitch. It was pretty easy.
Let me know if I can help with more info, etc.
Thanks,Mike
