I have finally started servo installation on my Dragonus SA and wanted some feed back if I am doing it right. the manual that came with the heli shows how to position the servo arms before installing them into the heli. they show all arms are at 90 degrees in various positions straight forward or to the side depending on where the servo is installed. When installing the arms to the front of the servo the arms are positioned correctly, when the arm needs to point from the side of the servo I can't get them to 90 degrees,the splines engage one tooth to the front or rear but not perfectly straight to the side.(radio turned on and all servos hooked to receiver,trims set to 0 and let the servo self center before installing arms) also the holes in the servo arms are extremely small as if only a z bend wire was intended to be installed. When I installed the balls through the holes with the provided screws it was extremely tight and I could see the plastic on the arm discolor as I screwed the balls in. I don't like what I see but have no experience to base my feelings on. I imagine that not having the arms at 90 degrees means my mechanical setup will be off and I am afraid that one of the balls may break out of the arm.....should I get different arms, am I correct by turning on my radio and letting the arms self center before installing the arms? :dontknow
