The Vision40 finally sold me on the 75mm form factor. With larger, more responsive motors and a digital video transmitter, this quad has plenty of power to justify its higher weight, and fantastic video quality.

Buy the "ready-to-ship" version with Walksnail vTX and ELRS receiver at: https://bit.ly/3qFNJHi

For other receiver types, buy the "built-to-suit" version (up to 2 weeks lead time) at: https://bit.ly/3WEhvYA

The fact that you've started to upload videos early to Patreon really screws up my YouTube algorithm... 😅

You meantioned at least twice, that these "pillow cells" are less performant compared to those in a different packaging. Doesn't make this CNHL lipos more performant than Tattu Funfly lipos as well since they come in a more square package? In this video (https://youtu.be/0j_xoeO1Las) your actual tests only show a difference between PH2 and BT2 but nothing that confirms, that "square cell" is better than "pillow cell". Would love to have proper evidence, that the form factor is the reason why they perform better and not just very good R&D on Tattu's/NBD's end. When looking at this video of yours (https://youtu.be/B8D0hOwTviU) one could say: get smaller lipos instead of bigger ones, because they last longer under "heavy load". In this test you had 4 different 1s NBD 300mAh lipos with a PH2 connector. Yes, they were almost always in the top 5, but you also had "pillow cell" Happymodel 300mAh and 250 mAh cells, there were inbetween the NBDs ones.

The reason that video did not test square vs. pillow is that result was achieved in a previous test: https://youtu.be/B8D0hOwTviU So the previous test confirms that square cell is better. This test further confirms that square cell + bt2.0 is best. That's how I interpret the results anyway, although I do admit at this moment I'm working from memory and haven't gone back and re-famliarized myself with the data before writing this comment.
