I have sent this to Van's Support but I usually get more timely responses rom my fellow builders
I have a question about the range of movement of the stabilator on my 12iS build. I start with the fuselage in ‘level flight’ attitude (measured at the longeron line next to the cockpit) as a base figure of zero degrees. Then I’ll hold the stabilator at zero degrees. From zero, the stabilator will rotate up (at the trailing edge) 18 degrees. However, it will only rotate down from zero 1.8 degrees (at the trailing edge). The measurements at the stabilator are taken at the main stabilator spar and confirmed at the upper skin over the spar.The movement limits appear to be established by the hinge stops (attached to the hinge bracket assemblies) contacting the aft notches in the F-1211C-R&L hinge brackets. Is this range of movement normal or do I have some hardware installed incorrectly? I have checked the PAP and cannot find the answer there.
