So I am almost done with the trim tab on the left elevator. All of the hinges are drilled and the trim tab edges are aligned nicely with the rest of the elevator. Only problem is that when I attach the threaded pushrod to the control horn, it is slightly off center with the exit hole on the bottom of the elevator. I followed the plans to mark the outboard hinge hole 3/8 of an inch from the edge of the hinge.
The only other thing I have noticed after looking at other folks pics of their trim tab hinge alignment is that my eyelet order is reversed. I don't think this matters much, as long as the trim tab is in proper alignment with the elevator, but perhaps I am wrong.
I think the alignment, or in this case the mis-alignment of the pushrod, has much more to do with where I drilled that first hole in the trim tab hinge. That, combined with the final placement of the hinge on the elevator side ultimately dictates where the pushrod will end up. Can some one tell me what stupid thing I did here that might have caused this?
I have no problem ordering a new hinge or digging out a sufficient amount of the elevator skin to ensure proper clearance of the pushrod. My main concern is how far over this forces me to move the trim servo mounting brackets on the cover plate to mantain a straight line to the control horn.
Thanks in advance for your comments/answers/thoughts.
