I have been getting qoutes for a drone to add to our inspection business. So far I have quotes from Aibotix, Ascending Technologies, Aeryon and Altus. We currently use a Draganflyer X4. These professional drones have a massive price tag attached to them and I am wondering how they can be so expensive compared to a cinematoghraphy drone thats carrying a red epic camera around a movie set. What makes them so expensive? Whats in there that can add up to 65K. If you ask the manufacturers you get the same answer. There industrial grade, there not mass produced in china, there safer more reliable. yada yada what separates a 65k dollar drone from a drone that can be built with the best motors and best ESC's on a solid platform. Is it the flight controller? Is the flight controller in a falcon x8 or an Altus what separates these drones from the rest? I was wondering if someone could shed some light on this for me.
