RClPlane,
I will say this about the Harmon Rocket ARF: AWESOME!!! I bought one for my son, who went from an Avistar 40 to the Harmon Rocket. This plane is extremely responsive and aerobatic. I powered his with an O.S. 46 and she's a screamer at full throttle. This plane is capable of any aerobatic maneuver the pilot can put her through. She's also docile and gentle at slow speeds. Easy take offs and landings are no problem. Give one a try, you won't be disappointed. Good Luck and Happy Landings.
