We fly on 500 feet and flying jets on it is alright, although if you ever have a problem it can be a little tight. We will probably add around 200 to 250 feet to make it 700/750 feet of pavment when funds get right. IMHO with 700 feet or more you should not have a problem getting any sport and most scale jets down. Jets Over The Heartland only has 800 feet and they have a very nice event.
