I do not know if these can be bought but they are very easy to make. It takes twice as much hinge to make these. Some people think less is better, but I think I need to make things as good as I can if my life is depending on it. This is by far stronger, and maybe even over-kill but I will bet this set-up is less likely to fail.

That is they were cut to intertwine, a gruesome task. But, it stabilizes the rudder to center point and greatly enhances the strength of the hinges. They work and look great. On the ailerons though, you have to remember the initial way to install the hinges creates aileron differential and that is important. It allows the ail to go up much more than travel down and that reduces drag during a banking turn thus eliminating or almost eliminating the need to use the rudder during a turn. At least, that is way mine works. I believe it is called adverse yaw. During the six or more years I flew my firestar I had to adjust the rudder hinges many times for they would bend in one direction and offset the rudder. The X hinge system fixed this and I now do not worry about the pressure and speeds I now fly. I believe the information is in the archieves but if not, I may be able to get the infor and pattern. Very glad I did it. my two cents.

See if I can figure this out. Cut half the loops off the hinge resulting in a stronger hinge? Lot of work compared using the whole hinge. There is no problem with current hinges or Kolb method of attachment.

Also, I removed the book-binding tape between the aileron and wing and didn't notice one bit of difference in banking the Kolbra.
