RE: Park Flyer?
With all of your restrictions it makes it hard to give you a specific model.
Try looking at Zagi's, The GWS line of planes and moutain models.
Remember most park flyers by design are not going to compare to the types of planes you seem used to however there is something quit relaxing about flying a GWS Tigermoth full bore (about 7-10mph) around the park at 10ft above the ground. You might find the lower performance models make up in flying satisfication what they lack in flight capabilities
