I was kinda annoyed when I figured out i needed a regulator too, but that was a year ago and I'm over it. [sm=lol.gif] Now I'm glad I went that route because an entire year of running with one has proved to me how effective they are. Now I'm just more annoyed at Great Planes for designing the plane with such a poor stock fuel tank location. Great planes obvisouly intended for the user to mount their engine inverted, while at the same time placing the tank too high in the fuse. That's design error as far as I'm concerned. But the plane is a great flyer and I'm forced to overlook a lot of that.
