I am hinging my skymaster viper rudder.
I am going to use 6 hinges total. One at very bottom by control horn.
I will also add blocks on fin to support the hinges.
My question is
Is the rotation point parallel to the hinge line. Meaning as I push the hinge points into the rudder will the all be in the same depth???
I am trying to get an easy way to line up all the rotation points on the hinges. (all the same depth)
Any tips would be helpfull

Hi Bill

no the depth decreases as you go from the bottom of the rudder to the top. Draw a line on masking tape from the centre of the radius on top and bottom and this is the hinge line/ pivot point. I think I drew a diagram and posted it on the "another skymaster viperjet" thread, but I'll have a look on my pc at work and see if I still have it

Measure the thickness of rudder leading edge at each hinge location. Divide that by 2 and mark the hinge with that distance from the pin. Install the hinge until the mark is even with the leading edge.
