If its only a two blade turbine I'd try flying between the blades at take off and landing, however if its three blades its a little more tricky, not impossible by any means, just that you have to keep your skills up to date? Hows that for a smartarse answer?
On the serious side I think you have a case as you have been flying from that site ands such an empennage is a clear infringement rather like the big bloody Tescos they have decided to build practically in my back garden!
