I'm working on the rudder stops and start filing them to measurement. While doing so I stumbled upon these findings which are puzzling me.
The manual says : " The proper 35 degree swing is attained when the clearance between the inboard trailing edge of the elevator skin and rudder skin is 1 1/8" when measured perpendicular to the rudder skin with the
elevator in the neutral position. "
I made a cardboard with a 35 degree angle and held that against the vs and rudder.
When I measure on the pilot side and hold the rudder along to the cardboard, I only measure 1/2 inch between the trailing edge of the end of the trim tab and the rudder with the elevator in neutral position.
On the passenger side, it's even a little closer, here I only measure 13/32 inch.
I'm not quite sure what to do now. What is the most important ? the 35 degree deflection on the rudder or the 1 1/8" distance between the elevator and rudder.
Actually I'm wonderiong if the cardboard method is correct ? The vertical stabilo skin has a little curve to it and the rudder is tapered and triangular. So i'm not sure if the 35 degrees measured should be 35 degrees according to the centerline of the rudder and the centerline of the fuselage. In that case I would probably end up close to and inch distance but then the 35 degrees seems hard to measure.
How did you guys measure this ?
