Just put a set on a PT-19. They dress a model up nicely. I had to get some help since I don`t have all the tools necessary, primarily drills to drill holes in the struts Then you have to tap out the holes to fit set screws to attach the struts to what`s left of the original wire landing gear on the plane. If you do install them, make sure those set screws are good and tight. The struts do absorb shock and help with landings, in my opinion, although you may find that you`ll have to adjust the spring tension in the strut ( not hard to do ). Hope this helps.
