One common question is "Where can I fly my radio controlled aeroplane ?"
...and the answer is (as it so often is) it depends!
If you're asking about a park flying model then the answer is almost anywhere, where it won't be a danger to people, animals, or itself! ...
You can probably fly your park flying radio controlled aeroplane in a medium sized park...
where there's an open space away from trees. You don't really want to be climbing trees or sending a child up there to get it back (health and safety and all that, do kids still climb trees?). Find a corner of the recreation ground far away from others and you'll be ok (but don't worry you'll probably still attract a crowd) ! Any common ground or quiet open public area should be ok for flying the smaller radio controlled aeroplanes.
Another place you could think about is a local industrial park at night when it's not busy, or a closed supermarket car park (or even a closed down supermarket car park!)
If you want to fly a larger plane then maybe a friendly farmer's field or out in the countryside (Last of the Summer Wine style).
... but if you have to have the biggest and shiniest on the park then possibly the park won't be the best place to fly your bigger and better radio controlled aeroplane. In that case you should seek out your local radio controlled aeroplane club and they will advise where to fly and also teach you the basics and also crucially provide the necessary liability insurance. Remember people have been killed by model aeroplanes ( or is that an urban park myth?)
Here's a little tip I learned: Look up Google Earth satellite view and look around your area for any large open space.
Use your imagination a little.
Another thing you could consider is indoor flying.
You can get micro model aeroplanes or helicopters which even fly in your house! Also you can fly in larger indoor areas like leisure centres or a community centre but obviously you'd have to organise this and book a room for a few enthusiasts - maybe a club. You'll soon attract spectators if you're a good pilot. Then there are also other indoor spaces maybe a warehouse or somewhere else that you can (legally) get access to.
Hope these ideas spur you on to find a safe place to fly your radio controlled aeroplane....................
