I have an [link=http://www.geistware.com/rcmodeling/calculators.htm]excel program [/link] like that written by a guy when he was going to MSU. If you come across him, let me know. I need to get him to modify it slightly. It does have a couple of bugs.

Scou,
What servo torque calculator you using? I can't move the rudder(phisically with my hand) against the servo's torque, for fear of breaking something. This servo is very strong, and the servo arm is 1" shorter than my rudder horn, so I should have a mechanical advantage. I just doh know???[sm=confused.gif] besides, we can't be putting "two" 2oz rudder servo's in a 1/4 scale plane[sm=spinnyeyes.gif]
