Hi Adrian,
We have been lifting heavy and expensive payloads for the past three years. We started trying to use off the shelf drones, but they were far too unreliable and could not easily customize them into the purpose built solutions we needed so we started designing and manufacturing our own. We have engineered out 90% of Chinese components.
We have only recently begun selling these drones commercially to local Civil Engineering firms willing to work with us to refine our products. The key there is having first hand knowledge of what is or isn't working and making improvements almost on the spot.
Just wanted to let you know that there are alternatives, and I'm sure we're not the only ones, who are coming out with real industrial grade drones.
We developed and manufacture our own flight controllers that use the same methodology for flight control across all platforms. We have six multirotor models that are modular and can lift from 12 pounds AUW to 48 pounds AUW.
This Y6 lifts 36 pounds AUW. With the payload shown here we can add 44,000 MAh for a flight time of ~40+ minutes.
You can also switch out the booms and motors with the smaller motors and props with less battery and still fly 20+ minutes.
These booms are plug-n-play so you can configure the drone that's the best fit for the mission.
So here it is configured to carry 18 pounds AUW
And configured to carry 36 pounds AUW.
We have the same setup for Quad and X8.
