Didn't really care much for the Acro performance (TWR) of a 2" outdoors so I recently rebuilt my 2" Whirlygig into a 3" (https://rotorbuilds.com/build/19157)
This little Tri is uses Betaflight 4.1.1 and its "fancy" motor-filtering to provide superior handling.
Specs
Build weight 37 grams only camera but 54 grams with 2S 300mAh LiPo attached.
Note: Picture showing the scale is the same Tri but with the older 2" props. (Weights the same though)
Hover time 8:45 (confirmed)
Acro time 3:50 (confirmed)
Video
Updated 3/28/2020 with Nano Whirlygig's 1st spring flight. (man I'm out of practice)

You went back from Dronin to Betaflight? Is BF back to being ok for tri's?
No reason to stay wth dRonin considering the lack of forum support, lack of development and lack of features.
Sounds about right, that was me commenting on your youtube video btw. I might hit you up with a million and one questins lol.
