You need to specify the All Up Weight. Thrust needs to be at least 2 - 3 weight. So you can look at the 380Kv tables for 3s with different props and it will tell you the thrust per motor.

3S is possible with large props like 17".

I tried 3s with same motors on Iron Man 650, without any camera and fpv gear, but with 12" props result is it couldnt even hover.

With 4S I was able to hover and get average hovering time, but with zenmuse and gopro, it couldt hover on 4S

With 6S everything works nice but flight time is really bad.

Please note that I made all these with 12". I ordered 15,17" props, waiting to test with them also

did you try your ESC Afro 20A tubes with 4S or 6S setup. Do you think it would be ok to use them ?
