I do all my repairs while watching programs on the lube-tube with my wife. It kills 3 birds with 1 stone: Spend time with th wife, enjoy the show, and most importantly fix my babys.
My p-51 I haven't done any maintenance on it except when I have hard landings.
That actually goes for all my planes. I just set them up and don't do anything to them after the maiden except check screws, glue joints, etc. That doesn't take long.
I would guess that you're relatively new to this hobby. The more you do the stuff to those planes, the easier and quicker it will become.
Use lock-tite! I can't stress that enough. Also, put a piece of tubing or something else to keep those clevis pins closed. Lost a c-130 because of that prob.
