Circus shoot Phantom 4

[Magicmanp4]

Quick question, doing a shoot tomorrow for a circus, aerial photos mainly, big metal poles everywhere, will that influence my compass etc..

The poles won't mess with your compass just your props, . You need to stay away from High Voltage lines - line transformers - these can make large magnetic fields which can mess with your drone. They also maybe running large 3 phase motors on the rides which are just like transformers, but they rotate, so I wouldn't fly to close tho those either.
