Dan,

I thought that would be the fix, but I wanted to make sure. I'll gently bend the joiner arms to match the ribs. It should only be 1.5 degrees per side.

Thanks,
Glen

I cant tell exactly what the issue is. It is fine to gently bend the joiner arms outboard to mate with ribs.

The clamps have no effect on the gaps. I only lightly clamped the joiner control arms in place, because I needed a free hand to take the picture. There is no play in the joiner control arms when they are assembled. The clamps only hold the assembly in place, as the front of the assembly bottoms out on the front of the inner ribs which leaves the 1/8" gaps at the rear. It appears the 30 degree angle formed by the ribs, is not a match for the 27 degree angle formed by the assembled joiner control arms.

Glen,
Try releasing the clamps that are holding the joiners to the rear spar. That may be causing part of the problem.

Let me know.

Paul,
I'm looking forward to the rigging manual part 1. I test fit my elevators to the horizontal stabilizer, and had no problems. I then test fit the assembled joiner control arms (no holes drilled yet), and noticed about a 1/8" gap on each trailing edge. I can't just push the control arms together to close the gap, because everything is pretty sturdy. I measured the inner rib angle, and it's 30 degrees. I measured the angle of the assembled joiner control arms, and it's about 27 degrees. It doesn't seem like much of an angle, but it sure makes a pretty big gap at the ends. I'm wondering if I'm supposed to bend out a 1.5 degree angle on each flange of the control arms, or is there another way to remove these gaps?
