In a previous UCD post, rumor had it that GP had shipped some models with and without required firewall thrust angle. I also thought I heard some one else say that they had a UCD that actually had LEFT thrust angle built in. Well,... mine is an example of just that. Study the picture below. Looking at the picture, notice the gap along the front right fuselage edge and the inside transition of the T-square. The vertical edge of the T-square touches the fuselage further down the fuselage, indicating left thrust. I still need to add 3 washers most likely in order to get the required right thrust. After reviewing some video of me flying last month, I heard myself say a few times "Geee, see how it pulls to the left when I gun it!". That got me thinking.
