 Barry, There are basicly three versions of position controls availilable for the N's and fergies. They all do the same thing in slightly diffenent ways. The three systems are:
The Fergy Positioner -~$80 from an austrailian outfit.
The Position Control you can make for ~$20.00 (Pictured above and many photo's in the Parts and Pieces Gallery Do a search on position control)
and
The Zane Thing- Made by Zane Sherman down in Georga. Pictured in the Parts and Pieces Gallery and labled unknown position control. Basicly a rod and two clamps. The position control basicly wors like this... As you know if you move your control lever up and aft. The lift goes up... and move the control lever forward then the lift lowers. The right side lift arm and control lever are right next to each other. Thus if you tie the two together with some hard linkage then you create a feed-back loop for control. Example... The 3-point lowers... the lift arms rotates down pulling on the control lever moving it aft. (control lever moves aft... commands the lift to rise...) Example 2:... The 3 point rises... The lift arms rotate up pushing the control lever forward. (control lever moves forward.... commands the lift to lower...) Thus position control. As the lift drifts with time it automaticly moves the control lever to command the lift back to the origional position. Check out the photos and the plans.
