Default RE: dual elevator servo setup help.

hey kid chuckles...thanks. now, i'm going to have to have a y harness so i can run these two servos off the same channel. so here's the problem.....and it might not be anything, really. on the u can do, obviously now, the elevator servos are on opposite sides of the fuse and ideally, it would be nice if they were located at the same point on these opposing sides but they're not. however, the only difference in location is latteraly (front to rear) and the height of their mounts are the same. that shouldnt mess up the geometry as long as i can keep the rods parallel to the horizontal stab. the length of the rods shouldnt matter. am i seeing this correctly? and of course, the servo arms would have to be 90 degrees to the rods when the surfaces are at zero. i dont know, i think i'm on the right track here. i'll have to just try it and see. i actually have it set up presently on my futaba 7cap using a pmix ...channel 2 (elev) and channel 5 ( gear ) and it works fairly well except the throws are marginal and setting it up so that it works is a real head ache, believe me. i fooled around with end points til i was blue in the face, and dual rates, sub trim...i hit em all. but the throw is like low rates which doesnt help when flying 3D. i'm going to have to get this reversing thing...no doubt about it. but boy does this thing fly sweet!!!!
