I am planning on a meet and greet at the park for people who like to run RC cars. Nothing big and it will be outside in the open area. Will there be any problems running our cars. My focus is security of others

You'll be fine but watch out for people

You shouldn't have any problem just take care of the people around you

I would think you would not have any problem as long as you are respectful of others

Talk to the office.

It's a good place just arrive early which I would reccomend
