About a week
I usually try to take everything apart on a Friday evening, then go through a detailed checklist . I usually find something to fix, but almost always minor. This is what takes the time.
I lubricate all the rod ends, check torques on the control system bolts and wing spar (check these, I have found loose nuts!) The wheel pants need to come off, possibly replace the brake pads, ...
So, take it apart Friday, work an 8 hour day on Saturday, 4 hours or so on Sunday, about 4 hours more during the week, and then put it all back together. Take your time and have fun.
