Flying from your own land
Unless you are situated in an 'Article 4' area you will be able to avail yourself of flying (for 28 days) unless the local authority take an interest in your activity on H & S or 'nuisance' grounds. This means that if your activity does not cause an unreasonable effect on others then it has nothing to do with the CAA (unless you have an accident)
Therefore if you operate in a considerate and careful manner (in relation to others) you should be ok. Choose a quiet machine and avoid 'overflights'.
