Went through a few trial and error cycles trying to get an acceptable result on the rudder return springs. Originally had spring "in line" with rudder pedal movement. This presented the problem of finding a spring that extends long enough and is short enough to not cause interference when compressed. The spring can't get out of the way when the rudder pedal is full forward. Decided to drill the attach hole on the fuselage inboard, at an angle, to remedy this issue.
First spring I tried was a 3/4" diameter X 2 7/8" long. These springs were too strong and seemed like excessive force on the rudder pedals.
A 5/8" diameter x 2 1/2" long seemed to work right.
