Vortex,

Checked out the pic of your dual pushrod system and I like it; clever method of eliminating the differential the two elevator halves will see with a typical split pushrod system. Probably won't be able to install that in the Javelin without a lot of butchering but I'll definitely keep this in mind.

Rbacons,

As you stated, trying to modify the Javelin is probably not in my best interests (other than landing gear and a few other minor points); the question was really more of an academic one- other than some quick and easy fix. I'll need to disagree about the lack of differential between the elevator halves, though. The pushrod is moving in two axis (well, actually three if you count the up and down movement the elevator imparts to the pushrod) as the servo wheel moves about its axis of rotation. The pushrod moves both fore and aft and side to side- the side to side motion imparting the differential in the elevator halves. Granted, it's a small amount, but it's still present. I suppose it's easier to visualize if you picture a split pushrod lying flat on the table with a vertical axis (perpendicular to the table) in the center of the rod. Moving the rod side to side about this axis shows that the two pushrods (split pair, that is) go through an axis of rotation- thus imparting differential to the elevator halves.

Keep it coming guys, more discussion is good!
