Perhaps I should add to my comment that our club rules limit three aircraft flying at anyone time, to prevent the sky becoming overcrowded and minimising the risk of midairs. 10-15 planes in the air at the same time? Don't think I would fly there.
It is also expected that if you are landing, taking off, or doing low passes you comunicate this to other pilots so that they can fly accordingly.
Good comunication and being sensible means every one can be kept happy.
