Greetings Sandor and others:

I have two questions about my landing gear if I may:

1) In the first photo, the red arrow is pointing to a cap head screw on the strut. It seems to me that turning this screw adjusts the tension of the trailing link spring. Is this correct? Is there an optimal adjustment?

2) It is very hard to see in the second photo, but a less-than-perfect landing put some side load on my gear and they are both bent slightly toward one side as indicated by the red arrows. Is there any way to bring these back to straight?

Thanks as always for your help.

Steve
