I am having trouble figuring out where and how to mount the ray allen potentiometer flap indicator. Does anybody in the system have a picture or suggestion as to where and how to mount this?

   Thank you for your help,

If you search the archives for my name/email and/or flap stuff, you should find the info for an easy installation.  Let me know if you can't find it and I will resend when I am at home.

Can't remember who I borrowed this from, but this is the way I did it.

2 points. The movement is non linear because of the hinge. It is great for

indicating flaps up or down but not partial flaps. Also if the POS

overextends it breaks and you will get no reading so be careful how far you

let it extend.

I mount mine in the tunnel with a small "L" iron that I epoxied to the flap actuating tube. Seems to work well there away from moisture. I get almost no reading on the first 3 degrees of flaps, but works well after that with the flap positioning system. I would add caution as was mentioned before - DO NOT LET THE SHAFT HYPER-EXTEND. I did and the replacement is $40.

I like this simple solution to mounting the POS-12.  It is inside the airplane (keeping it out of the weather) and easily accessible for maintenance.  This is my implementation(see attached picture).  To get the 1 inch travel, I found that having the arm attached close to the outside of the flap tube worked well.  I just bent a piece of scrap aluminum, drilling a hole close to the flap tube.  I used a 4-40 bolt (with loctite on the nuts) and a short piece of plastic spacer material (from Lowes).  This eliminated possible interference between the POS-12 arm and the metal tab.  To keep it even simpler, I just placed the angle bracket under the cushion clamp and it seems to work fine.  (No drilling in the flap tube.)  The total travel of the POS-12 is just about 1 inch of the total 1.2 in available.  The comment was made that this provided a non-linear representation of the actual flap extension.  This is true, but I'll be calibrating it for the VP-X display with actual flap position measurements that should be close enough.  Remember, many folks don't even bother with flap position information, relying on their eyeball measurement by looking out the window.
