Well, as promised ..... between forest fires .... I googled for 

jackscrews.  I started with '12 V jackscrew' and got all kinds of weird 

stuff .... so went to '12V linear' and hit paydirt.  There are a lot of 

sources out there.  The price isn't bad if you consider a Ray Allen trim 

servo is $145!!!!



http://www.route66supply.com/store/page26.html in the $120+ range



http://productsearch.machinedesign.com/mdproducts/12v_linear_actuator 

has listings for 515 companies, and no, I didn't check them out.



http://www.servocity.com/html/12v_linear_actuators.html has them for 

$100 .... max speed .5"/sec.



or look here:

I think that with the linear actuator and the torsion spring concept 

.... there's a very good solution to the rudder trim scenario.
