Your engine should be able to power a 4Star 60. I would add an inch to the rudder and build it as per the kit. Great flying plane - I recommend it as a trainer. It is not that much harder to fly than a trainer. The price is reasonable, it flys great for what it is - you can use it to sharpen your flying skills. I have two that I take out occasionaly and let my buddies fly them in between their giant 3D and scale stuff. They enjoy them as much as I do to just relax and fly some nice 'sorta' precision flying.
