Roger,
since i'm building a "relatively" small plane, at 60" span, I set up my tabs on the elevator with 2/56 ball and socket joints, and threaded rod, my problem now, is that i have more movement in one direction than the other, because of the offset from the hinge-line, is this ok? or should i figure out how to get the balls even with the hinge line for even boost each way? i assume i would want more boost in the up elevator direction than down.
thanks,
Dennis
If it were an aerobatic airplane, you would want the same movement in the up and down position, but being a Warbird if I remember correctly, it would be OK.
You should as much as possible get the ball in line with the hinge line.
But because you are using a very small boost tab, you should consider the nor 1/2a control horn and the small nylon clevis. This would help keep the weight down which would also help in the balance of the control surface.
