I have flown with Clarence Grubbs on a number of occasions, and he has a pretty cool way of doing this. During construction, he installed a small spirit-level on the passenger side longeron where he could see it from the pilot seat. He set this so the bubble was centered when the aircraft was level. During cruise flight, he adjusts the flap reflex for 1.5 degrees "down bubble", I think it is. He believes this to be the minimum drag angle for the airframe on his aircraft. Actually, now that I think of it, he also has a "cruise" mark on his elevator trim handle, and the flap reflex works out so that his aircraft should trim out level at that point (elevators in trail). Guess he cross checks both things. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html Builders' Bookstore: http://www.buildersbooks.com/lancair >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
