Finished the leading edge of the rudder tonight. I don't know why this part gives so many people trouble. I didn't find it especially challenging. I can see the value of an extra set of hands, but I managed just fine by myself. I also put the rod bearings on the leading edge of the rudder. The manual didn't explain to do it yet but after examining other builder websites I notice about 50% of previous builder have installed them at this point. So I got the data from the blue prints and installed them now instead of later.
