I was surprised at how insensitive the rigging is. Fairly course adjustments to the lateral rigging have only a small effect on roll trim. My aileron trim tab (I only have one) had about 1.5 CM of deflection. It took 0.4 degrees of wing adjustment to cancel that, and get the trim tab back to neutral.
I know its not authentic Swiss army, but it means a lot to me :)
The final rigging check involves locking the control surfacse in the exactly central position, and then measuring the position of the control stick in the cockpit. Once the controls were measured and fixed, I installed some strings in the cockpit and placed a knot where they lined up with the top of the stick.
In flight, I trimmed for level flight, took my hands and feet off the controls and verified that the knots still lined up precisely with the stick. - They did, so now I know the rigging is correct and in cruise flight, all the control surface are neutral.
I wanted to see if the Jungmann touched down in the proper three point attitude, but I'm afraid that my not having flown it for three months combined with a 12 kt 90 degree crosswind produced a landing that had birds and people alike rolling on the ground wth laughter. I need to go practice in secret somewhere, prefreably somewhere with a grass runway.
4.9 hours now and no problems so far.
