I have experience building quad copters with PixHawk before. I was wondering what set of components would I need to make a quadcopter (maybe with two motor on each arm, 8 motors total) with a payload capacity of 40kg. Similar to the DJI Agras T40

I was looking for inputs from the community. If someone already did similar projects and how their ones perform.
People who want advice should not be forced to pay for a subscription service.
Nobody is forced to do anything. Don’t you want to figure these things out for yourself with a simple tool? At the cost of a set of props?
Would you rather post a laundry list of hardware and ask if it will fly?
I do not want to financially encourage closed source payware.
What experience do you have. Possibly you like to start with a smaller craft. Then focus on power. Large props can be very dangerous.
Cool. We look forward to your Open Source version.
I know you are being sarcastic but considering this is a web page that has probably not changed in 20 years, uses universal mathematical formulas, could be 50kb of code on Github that anyone can download, and the only real “moat” is the compiled data that users would happily contribute, well…
Having a python library that can run every possible combination hundreds of time per second to find the best configuration, able to be integrated in any sort of software, that would make a lot of people happy. I realize that making something free, open source, and better, is a foreign concept to many in this field, which’ considering where we are and what ArduPilot is; is ironic.
I have a similar and successful solution: using an OCTO X frame composed of 8 Hobbywing X9plus, with a wheelbase of approximately 2.2 meters. When using two 14s78AH semi-solid lithium batteries (4.45v, each battery weighing 13.5kg), it can hover for about 30 minutes with a load of 40kg. This drone weighs about 25kg when empty, and with the batteries, it weighs approximately 52kg. At sea level, it has successfully carried a load of 50kg. I am not aware of your other specific requirements, but I hope this configuration meets your needs.
Please ensure safety and I recommend first trying a 36-inch QUAD as a test.
What is ironic is that you do not know the difficulty of finding users willing to contribute data.
The software has a good price point and they do use the money to collect data. You are not paying for the code, you are paying for the data collection.
I can talk, I create free software: ArduPilot methodic configurator and am willing to do that!
Still I ask users to contribute datasets created using the tool, and they don’t.

I would definitely pay for a subscription to use the dataset, that’s different. (i mean the ecalc one, as it contains a huge variety of test data from a lot of parts, often compiled with user testing, so it is indeed quite an investment)
Are you willing to pay for a “ecalc Multicopter dataset” or are you willing to pay for an “ArduPilot methodic configurator dataset”?
Which one is it?
This argument over paying a pittance to use industry standard software is derailing the topic.
If you’d like to explore creating an open source alternative, please start a new one.
