I have the same as you. It is not that I think the plane is incapable...it is me. For some reason I get disoriented quickly doing the loop..well I did. I can do inside and outside loops on the electric and have done a couple of full loops but it takes a toll on my vision for some reason. Also for now I keep the plane close and venture a little each day. When the sun is beaming in my eyes I will loose the plane for a sec and I begin to look for tires or tail wing. I keep it high enough just incase so I will have time to recover. I almost lost it Sat morning due to the sun and did some unplaned rolls and an unplaned short inverted flight but I did finally regain controll but was very close to the ground. I heard guys at the local air club to stay 3 mistakes high and I have been watching them. I believe in 4 high for an untrained person like myself and it came in handy yesterday.

Also I tried out the 10x7 prop and it seems to work well. To me it is a little sluggish but more thrust. It made the very slow fly bys neat. Especially when I was about 10 inches off the runway and would putter along and then mash the gas...that was fun
