Commercial Grade2019-05-30T13:41:11+01:00

There are various levels of drone craft – toy grade, hobby grade and commercial grade. Commercial grade drones will have a raft of features that allow them to be used in a business environment, such as flight stabilisation, mounts to allow cameras to be changed, return to home and sense and avoid systems.  They will be more rugged in construction, often contain multiple batteries to extend the flight time and of course be more expensive.

Hobby Grade2019-05-30T13:21:47+01:00

There are various levels of drone craft – toy grade, hobby grade and commercial grade.  Hobby grade drones have more sophisticated sensors and the ability to perform tasks based on location as well as replaceable parts such as propellers.  As they are not designed for absolute beginners, a hobby grade drone may require some flying experience.
