Depending on the type of work we use a variety of craft to suit the task and payload. On most occasions we use High Resolution cameras mounted to a 3 axis Gimbal to give a very stable platform. when it comes to Survey or inspection, we might change to a FLIR Camera to provide the client with data used to diagnose wear of components and efficiency.
The craft we use have a proven track record for reliability, loiter time and stability. When airbourne we need to ensure that risk is reduced with proper maintenace records, Flights are recorded along with battery logs for inspection by the CAA.
