Forget about flying DLG or most gliders for that matter at any model flying club. While some members would be OK with it most will have an issue.(club rules or not!)
One reason I stopped flying at clubs was all the heir-achy within the club members themselves, especially when it came to the models they fly.
I now fly smaller electric models and DLG gliders (responsibly) at large local parks in my area and never looked back.
