I only chocked the airplane and did the adjustment. Of course, removing the
plugs would help but I didn't find it necessary, I just spin the prop slowly
and carefully. Don't forget to put some wood blocks under the outriggers if you
have a mono like me.

But I didn't go overboard (except making sure blades are at the same position
with the protractor when you swap them.
