(ppsel03) ________________________________ Message 1 _____________________________________ Time: 05:17:32 PM PST US From: "Bud Yerly" Subject: Re: Europa-List: Re: Autopilot Servos Will, The 3:2 is to give the servo a bit more more throw. The pitch tube only moves about 1.25 inches which translates to a very small movement of the pitch servo arm. On the pitch servo in the rear, it takes a fairly high block or bridge. Just make it robust enough. It=99s dimensions escape me as it varies by servo. Depending on your servo choice and orientation, some fiddling is required to get it fairly level and yet clear the main tube and above all, be serviceable. Just make sure the servo can never jam the flight control and is robustly attached to the airframe. Regards.

Is there any reason for the 3:2 arm on option no2 for the pitch servo. Would it be possible just to build a "bridge" over the rudder wires to bring the servo up to the right level?

I did this in 1999 on 419PL when I started building it. I don=99t do this any longer as taller passengers tended to dislike this loss of foot room as it puts their knees higher than comfortable while flying along. OK for those who fly with their feet on the rudder pedals or are a standard sized 5=99 10=9D. Also, these are heavy servos (Navaid, Blue Mountain, etc.) and weigh about 5 pounds. If you put the battery in the front, watch the weight in the cockpit. Strive for the 60-61 inch empty weight CG. You=99ll have to keep the panel light. These are very long servos also, so in a crash, just unscrew it and it makes an excellent club for survival. This setup under the feet also is a bit tough with the Garmin, Dynon, TruTrack and GRT servos. These light weight servos (about 2.5 pounds) are very good also, plus they have a smaller footprint, but they are taller. Reducing the foot well even more. Here are two other ideas I have used for quite some time. 1st is a design I made to put the servo behind the baggage bay. See the drawing. It is dumb simple. It is a 3 to 2 arm on a bearing and two push rods so as to allow the servo to move about 45 degrees. Bob Berube and I consulted on this and I have made it my standard for retrofits where the only place to put the servo is behind the baggage bay. It can be installed after the top is on in a finished airplane by access through the D panel. It is not comfortable. In all my aircraft, the roll servo goes under the pax seat. Make a simple metal plate of .060 aluminum and four nut plates to the face of the inboard seat hole. Attach the servo to it. Make an arm and attachment bracket for the stick. Fab a fiberglass cover to prevent the pax from impacting the arm. 2nd is a simple extension to the stab tube attachment point and hook up. Pretty simple, easy to bolt up if your plane has access panels which are positioned properly. I always have three access holes. A 4 inch sight hole for the MAC trim servo, a 6 inch abeam the mass balance arm as in the book. I then put on the port side a single 6 inch to access below the pitch push rod to stab tube attachment. If you have those small Europa mandated sized holes for drug addicted anorexic maintainers, this may be painful to try unless installed during the build and access holes are well planned. Always plan your servos so they cannot go over center and jam the controls. Many servos come with limit arms to prevent this, use them. The limit arms typically allow 45 degrees of movement max. Why use 45 degrees or close to that is to allow the servo to have a larger movement as the clutches and servo settings do not work well when the servo is limited to a full throw of less than 30 degrees. I have better drawings in my archives, but it will be a while to get them as my servo was hit by lightning and fried so it needs to have its hard drive recovered. Just a thought as legroom in the Europa is at a premium. Regards, Bud Yerly Custom Flight Creations, Inc.

From: "ppsel03" Well, iOS will have to allow for free installs before I'll tackle it. Paying to share a free app makes no sense... Have added SKIGULL to the listed simulator for anyone interested. And hopefully, improved the ease of use a bit...
