I'm sorry if I offended you Damnathius, but I also am speaking from about 50 years of experience in flying models, all the way from rubber powered back in the '30's to 1/4 scale and sport since 1958. My mentors convinced me by study and practical experience how important thrust line adjustments are for RC aircraft. True, if you only want to go straight ahead at a constant speed and no aerobatics, you can dial in rudder trim and get by quite nicely and it is not needed. On all my new planes, I often spend quite a bit of time on the initial flights to tune in the thrust settings so that I get no deviation in attitude with throttle changes as it makes the plane so much more pleasant to fly. I have no objection to building one without thrust settings but, for my own pleasure, I dial in whatever it takes to make that particular plane fly correctly under all throttle settings without my having to fight the trim tabs.
