I sent the original secondary back to Rotorway to have the 30mm shaft replaced with a 35mm shaft this was a requirement from RW. Image 1 shows how we blocked under the forward skids to level the frame to install the new secondary. When the frame is perfectly level it is required to level the secondary assembly this took some time tweaking to get it right. This step is very critical and I was glad to have Homer there for this one. Image 3 is a close up of the secondary assembly installed.Note: The installation requires metal shims and some removal of excess metal so that the proper fit is achieved. Went to the local machine shop for this task wanted to be right on the money and it is.
