<div>About 2-56 steel rods...whether adequate or not for the 2 meter jobs. I think this material is borderline even in short lengths of 4-6 inches. I've had rods bend like pretzels before. </div>
<div> </div>
<div>I employ 1/8" carbon tubes to reinforce the steel when steel lengths are in this range. The tubing has .078" ID and fits the typical 2-56 rods perfectly. It weighs next to nothing but adds terrific bending strength to the rod. I highly recommend it for a significantly lighter solution than 4-40 rods and clevises<br>

First saw that servo being used by CPLR. Only 50+ oz torque, but lightning (.04) fast at 6V. Once again though, this is personal preference or could be necessary depending on your CG. They both work great though.</SPAN></FONT></div>

<div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The pull pull seems to be the lightest and possibly the easiest way to go. The twin servo’s also seems easy but adds another servo. I don’t have the small servo’s required so that’s a consideration as well. The deps seems to be a good way but possibly the hardest of all to install. The old tried and trued Y pushrod is what I’ve used for years and have always used a bearing tube where it exits the fuse. This is a composite fuse already painted and I’d rather not screw it up by trying to put a former for the rear of the pushrod Like Dave has in the Focus.</SPAN></FONT></div>
