CCMAHAL, the holes in the aluminum landing gear was severely off in mine. I used a small rat tail file to open them up so they would align. I did replace the bolts holding the alum. brackets in as well with some aluminum bolts. My brackets were very loose. When everything aligned, I soaked all the wood with thing ca. I also had to cut the slots for the gear as well. Then I used some aluminum flat washers with the bolts to hold the gear. I used blue loctite. Then I used thick ca to keep the aluminum washers from sliding. I have about forty flights now with no issues with landing gear.
