RE: What is the average safe flying distance?
Re: "go to the nearest club and watch..." < great advise! If you can see most of the planes most of the time then you should be ok. A lot of flyers when they started out had trouble telling what the plane was doing. A 6 foot wing at 500 feet away looks pretty small but you get used to it. Thats why trainers are 60 to 70 inches so that you can get used to how the plane looks in the air at the same time that you get used to flying it. Once you get experience and used to the look of the planes you may be able to get into smaller planes such as the World Models Super Sports with a 56" wing. I had a plane with a 48" wing. I could keep track of it but it was a bit smallish for my liking. 56" wing planes are the smallest I will fly now.
