No one has really discussed leverage.. I try to spend some time setting up the linkages where the servo has some leverage, and the horn is rotated more in line with the linkage.. this will put a lot less electrical load on the servo when it gets into position..
My best example is probably BVM's flap setup on his jets.. they emphasize that in the manual.. using the shortest servo arm you can, and the longest flap horn you can.. lowered demand..lower constant current
