Hi,

One word of caution regarding my setup shown in the last pic. I ended up replacing the ball links that were attached to the elevator ends of my setup. I found that they wanted to make the horns on the elevator torque rods turn on the threads since they essentially push/pull on the side of the horn. Once the horn turned on the threads, it resulted in an offset in the elevator halves. (Not a good thing!) I ended up replacing them with standard clevis' which will not allow them to turn on the threads since the pin of the clevis prevents it from rotating. I left the ball links on the servo end, but have the regular clevis on the elevator end and it seems to work fine now with no tendency to rotate on the threaded torque rods.

I don't have a pic of the replaced ends, but they are just regular 4-40 clevis.

Johnny,
Your probably right regarding the hardwood support as opposed to the balsa I used. I know on the Zero with it's very short nose that it tends to result in a very tail heavy condition, so I wanted to limit the amount of weight I was adding to the tail section. I figure there is still enough strength in the balsa stick to adequately support the torque rods. It just gives them a surface to mount to and allow even push/pull on the rods.

Later.
