Making an S bend in the pitch horn and ending up at the cone hinge would give you a 72-degree pith horn with an odd shape. In order to have a 90-degree pitch horn you would have to cross the cone hinge and end up at the teeter hinge like on a Bell.
This would cause severe pitch coupling so strong as to render the helicopter uncontrollable. All of this has been said in past posts and most likely will cause a lot of pain on the part of the participants on this thread if I have to repeat my comments. Please read the past posts as indicated in my response to vorticey above.
