    Subject: Bendix M4 Autopilot
    --> Commander-List message posted by: "Ray Mansfied" <hcourier@cox.net> Am looking for a Bendix M4 autopilot computer, model # 5536. Does anyone out there have one to sell that works? My autopliot quit working quite a while ago. One shop said it was beyond economical repair. Another shop, the guy's worked on the M4s since 1961, said it could probably be repaired but needed the computer. Let me know if you have one you are willing to sell and the price. I fly a 680 FLP, thank you. Ray Mansfield hcourier@cox.net

    --> Commander-List message posted by: YOURTCFG@aol.com HI KIDS. I had the privilege of hosting the TCFG historian, Barry Collman at our home this weekend. Barry and Chris Hagg are spending three weeks at TCAC looking through the old records. They have uncovered some amazing tidbits. Like, the first Commander to receive Pressurization was not the 720. A 520 was modified as far back as 1956 as a test bed for the new system. We had a great time talking Commanders. We jumped in triple 2 and flew to Scappoose Or. for lunch and flew the canyon rout back home. It was a great afternoon. Barry will be another week in Arlington. Hope al is well in your world. jb

    --> Commander-List message posted by: "tylor.hall" <tylor.hall@sbcglobal.net> Ray, You may want to contact Moe Mills. He just took his M4 out of his 680FP. He may be willing to part with parts and the manual. Make him an offer.

    Subject: Re: Skydrol or 5606?
    --> Commander-List message posted by: "Lowell Girod" <dongirod@earthlink.net> Commanderland; Since everyone is talking about hydraulics, I have a question. My 560E with its 1000-1200 PSI will not turn the nose wheel if the airplane is not moving. Is this normal? Or do I have a problem and need to do something? I normal just use differential power and or brakes, but it would be a problem if I ever needed to taxi with only one engine.

    --> Commander-List message posted by: "Jim Addington" <jtaddington@charter.net> Ray, I don't know what Mason Chevillier had in his, or the condition, but I know he changed to a new one. He has a 680FP.
