Check with Mr. Morris. I believe he makes  flap horns with wider spacing between the holes for just this purpose!

P.S. NEVER use clevices!

You can always do this...

That's  a cool Ringmaster---had to look twice to make sure! (the flaps of course!).

The main issue with doing it that way is that you have a couple between the two control rods that tends to twist the horn. To be honest, I am not sure how big a deal it is.

Another way is to only use the ball link on the Bell Crank to Flap horn, and then use a simple L bend with soldered washer flap horn side of the elevator rod. Then put a ball link on the elevator horn. This still makes a couple, but the coupling is 1/2 or less of the 2 ball links on opposite sides solution. Another way is to make the little cone standoffs shorter. That will also reduce the size of the couple. I did that one time on my lathe because I had clearance problems---especially in the tail of the plane with the normal standoff.

I go one step further and just use one bolt through both ball links with the horn in the middle.  There's a bit of a twist effect on the horn, but as long the horn is stiff it shouldn't be a problem.
