RE: Seagull Spacewalker - Elevator Weak?
I doubt you'll be able to control it. But like I said, the technique is sound; ithas and is being used on thousands of radio control and control line airplanes.
If you are still concerned, don't use the connector, use a wye'd pushrod with a horn on each side. You can even leave the connector in place; belts and suspenders. If you do make up a wye puchrod, I'd bind the joint with copper wire and solder it. If you use wheelcollars and CA you are in deeper water than with the connector!
