my balance is at 5" also right now. the flat spins aren't super flat yet but ahven't experimetned a whole lot yet. i am about full thorttle towards teh end of the spin when it is getting flatter. mine won't slow down that good but i ahve a 16 8 prop, i wish i could get like a 17*4W or 176 but looked at apc's website and it loks like i am about stuff wiht this one. mine doesn't harrier to good, wants to wing rock some. kife edge is good, slight roll coupling. i have got my rudder on pull pull w/ tons of throw, not sure of exact amt but a lot, the elevator is also maxed out. i ahve the ailevators set up but couldn't tell much of a difference tosay also they did make it do a funny flat spin. anyone else using these and how do they help. i am using the new futaba 9caf on it .
thx
