I'm more asking than stating.
In the airfields guide, which is more readily available to us weekend warriors, it is stated that no circuits are to be flown to the north of the 09-27 and to the west of 03-21 the smaller circuit on the pic, which are rarely used - then I would presume there is a valid reason for not flying there. If you approach the field, the RC field is very obvious, and that should be the reason then.
I've added this pic for infos sake. The Rc field is 450 m from the threshold of 09 - safe distance by me, and they fly to the north. If you have a look at the circuits that I have added, and the position of the RC field - to go flying there, is looking for trouble. Even if you do not know the field, to go to Rhino park you should know not to fly to the north of the field.

My soul called, and it wants it's life back. Only one thing to do. Let's fly.
