RE: WHICH ARF?
Hey, RW, long time! How have you been?
I'm on my second Tutor after the first fell victim to a broken up line. In the middle of the best contest flight I've managed, to date, of course. With the OS 46 LA, it's a killer package. The Cardinal is less popular out our way, for some reason. But the differences between the two are pretty small. Both are straight and light. The hardware and covering leave a little to be desired on both. In either one, I would replace the pushrods (with CF), wire LG (with aluminum), and put aluminum motor mount pads on it. Over all, I think (and this is the opinion of a pretty rank amateur) that the Tutor flies a little better. But it comes down to your preferences, I think.
BTW, we've had several each of the Nobler and Oriental and they are both excellent, too.
