I was playing about with my SC tonight and decided I didn't think that the rudder or elevator were moving to each side as much as they should. I'll limit this thread to the rudder, as I have not played with the elevator just yet. My battery to my old camera is about to die, so the focus may be off a bit on the photos attached.
I laid a popsicle stick on my table and measured it at 6" long. I marked the center line at 3" and then increments of a quarter inch from the center outward. At first I slid the stick and held it vertical against the vertical stabilizer, but later I simply let it lay flat on the tail piece to see the readings as the rudder was moved about. Unfortunately, the lens angle can actually make some of the readings appear different than they are. I seemed to get an equal throw of about 1/4" to each side when the tx was at zero trim and the stick was moved to change the furthest movement of the rudder to each side. Before any of this was done, the servos were each checked to ensure they were centered and the tail was looked at to make sure it looked centered.
I know I can adjust things with the clevis to each or even changing the servo arms positions, but I want to keep any adjustments to the movement of the clevis or perhaps moving the control rod to a upper position on the control horns. I also know that I can trim the thing with the tx., too.
Is 1/4" pretty much the acceptable distance the rudder should move outward or should it be adjusted to move it more toward 3/4" or so? I am not a pro at flying this bird, so I didn't really want to start moving the control horns closer inward at this point.
Any thoughts on this or are things pretty normal at the rudder so far?
The weather and holidays have not been great for getting any flight trials behind me recently, but I am having fun in doing some mods, regardless.
