yes on measuring the Flap angle throws, but I just use a deflection gauge to measure angle. I also measure elevator throw at the root. The alerons are measured at the tip. Don't remember what my elevator throw is (can measure it if you need) but it isn't a lot. I find the elevator on the Classic Fash is very effective and can in fact be pitch sensitive if your CG is a little aft. As for Expo, I use about 30%, but that is more of a personal thing I think.
