This allows continued use of full servo travel and removes the cable tension from the servo shaft and mounting grommets. The servo is connected with a short link with ball end fittings.

<P class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face=Arial color=black size=2><SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial">Ackerman exists if the rudder has control horns (as opposed to a wheel, which is very hard to build into a rudder). The only ideal way to have constant tension is to use a symmetrical servo arm that is offset from its pivot (servo screw) the same amount as the rudder control horn attachment point. This will work every time and is simple, however with a 1" thick rudder post and two 3/4" control horns you will need a 2.5" servo arm (1.25" each side of center) and the servo throw will only be equal to your rudder throw (maybe about 30 degrees) which gives you poor mechanical advantage and poor use of your servo. If you use a shorter servo arm and more servo throw the cables will go slack. The round servo wheel is a compromise by offsetting this slack tendency and letting you get more servo throw. It's not
a perf
ect match but it can be very close.</SPAN></FONT><FONT face=Tahoma color=black size=2><SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Tahoma; mso-color-alt: windowtext"><o:p></o:p></SPAN></FONT></P>
