The 53 is a magnum and probably I am just expecting fun-fly performance out of a heavier plane. It hovers at just above half throttle but the pull out is slow, the irvine would be a good choice I was more giving an example of how the 46 wouldn't be enough for a fs. My opinion is that I actually think the freestyles were hyped at the time and they really are not stand out in performance. I know there are people out there that love their fstyles but I really dont think much of mine...
