Kenny: I was told that the further out of the hinge line the better since with the horn being further backwards there would be more strength and less backward movement of the airbrake when deployed. I opted for a happy medium...in the centre of the airbrake.

I don't know who told you that but I believe that the opposite is correct. If you put the arm at the outer end of the brake you will run into a problem. If you leave it like it is and look at the linkage while you add pressure to the speed brake you will notice that the servo arm is moving upwards and to the back of the plane before it moves forward towards the servo. Now if you take a horn and place it at the top and move the brake, most of the travel is forward towards the servo. I quarantee if you move the horn your problems will go away.
