I'm afraid that a 4 lb airplane cannot be described as a parkflyer. Being as your a newbie, I won't go into preaching, but a plane of that weight can do some serious damage....If you have an abandoned field that you can fly in, why bother and take chances with the park. I ply parkflyers exclusively and don't fly in parks. I would never consider flying anything larger that a Mini Ultra Stik, or a foam J-3 Cub in a park, and that would be a 6:30 AM when most are asleep and a children are home watching cartoons. I suggest that you also contact your insurance agent about this. Most home owners insurance policies will cover liability on what would be considered a toy. I don't think yours would qualify, and therefore you should think about Joining the AMA, if for nothing else, to get their liability insurance....JMHO...Pat
