Think minor language thing. @pineapple think you meant "Industrial grade" UAV enthusiast as in commercial or industrial applications for UAV?
Most people on the forum here are hobbyists or just tinkering or trying to get "toy-grade" things working (stuff that is meant to just work off the shelf with what it comes with not components). There are a handful of us who build from scratch but still mostly in the 5" size range and for acrobatic or "the joy of flight" and a handful of others who buy DJI or similar to get some awesome aerial views. Occasionally someone in the "commercial" or "industrial" grade category comes through here but not a lot of regulars just FYI.
You could also say there is a "sector" or a "market" for commercial/industrial drones but a whole "industry" implies many sectors within that industry and is typically used as a high level category like the "semiconductor industry" (billions of little chips made to go in everything)
We have a studio, and we have developed two mount series on DJI's UAV, so that the UAV can meet the needs of industry applications, such as fire protection, power, police, forestry, environmental protection programs, etc. Based on the flight control of DJI, the UAV with a load of 10kg and a flight time of 40 minutes and a heavy load of 60kg are manufactured. Inspirational to popularize UAV operation!
