put less elevator throw on it. You can do that easy on the arf FS because just changed in on the elevator horn. If you take some tail weight off and make it more noseheavy your manunever won't be as tight. The way it sounds, give it less control on the 2nd part of the loop. Your loops will come easy after you practice them and will look good.
Just watch that you don't to a hit with the ArF FS. They aren't made that strong. The fuselage it hollow, and the motor mount is really week. I braced my motor mount up big time on mine.
Have Fun
