Autopilot for 337 - Cheap!

I have basically a complete Navomatic 400 series autopilot out of a 1973 skymaster. Let me know if you have any needs - Letting it go dirt cheap!

Cool Big Cheese

And 'cheap' means? I'm always interested in spare bits, and I going to rescue my own 337.

Make offer!

Make an offer! Let me know what parts you need and name your price. I can post pictures and part numbers

Don't have a good set of rear or front engine baffles?

Thanks!

Mike

Navomatic

Not to lowball, but ine works. That said, having spare ailteroon elevator servos, DG, control head, main processor, etc probably not a bad idea.

$500 for the whole thing, plus shipping?

Autopilot Information

Hi David,

Sorry it has taken me a little bit to get back to you. It has been too hot for me to work in my hangar to pull the components until last night!

Here is what I pulled so far. If you could, let me know if I am missing anything. Also, do you know where the servos are located for this autopilot system?

Smile Servo location

The aileron servo is in a panel on the passenger side wing. I think the panel was about 2/3rds of the way out.

The elevator servo is behind the long panel on the pilot site boom. Its held in by 4 screws accessible on the outside of the boom.

Do you remember if it was it all working when it came out?

Servos

Hi David,

I didn't realize it but one of the mechanics that helps me with my aircraft had already pulled the servos for his airplane. I had completely forgot until he met me out there and asked what I was looking for!

Anyhow, if you are still interested in the remaining items, I would drop the price to $300.

Thanks!

Mike

There are several Skymaster being parted out. Might be able to find what you are looking for from them. Check out Barnstormers


https://www.barnstormers.com/Cessna,...lassifieds.htm

There is another one here in Michigan at South Haven that I don't see classified for right now.

We are chasing some ghosts. What would you be willing to sell just the brains, control head, etc? Do you still have?

My email is bigcheese@potomac-airfield.com 301 248 5720

Thanks

Autopilot parts

This has been going on for a while. Tell me what you got and what you want and I will take it. I am trying to get my autopilot up and running. Thanks,

Hi Dan

Mike doesn't have the auto pilot components any more, I grabbed them as spares for my plane mid last year during one of my trips to the USA.
