To pushrod or not to pushrod?
Ok guys here's the deal. I'm bulding a Midwest Citabria and am up to the point where it's time to set up and install the servos. The plans call for a single elevator servo and a pushrod to the rear of the airplane connected to a Y going out to each elevator half. Here's my issue, I have this fear of pushrods flexing and a fear that pushrods in a Y going to each half of the elevator will cause uneven deflection through imperfect symmatry. I would love to install two elevator servos in the rear of the airplane but would have to add weight to balance that. I've tried pull pull elevators in the past with poor results (I'm redesigning that airplane also). Am I crazy to think that pushrods are going to flex and that a Y is going to induce a rolling moment? What do you guys thing I ought to do? Thanks for the help!
