A job that took a lot longer than I expected was fitting castellated nuts and split pins to both control stick bracket bolts. The split pins just did not want to go in.
Until now I just had the control sticks temporarily bolted in place but I figure they're never coming out again now, so I might as well fit them properly. I tightened up the castellated nuts but for the life of me then had a bigger of a time getting the split pins in. Anyway, they're done now, so all good.
