Will variable PWM on your 3" Cinewhoop make it fly better, should you upgrade?
I compare 24kHz, 48kHz and variable 24-48kHz using Blackbox on the 650gram AUW Eachine CVATAR 3" 4S Cinewhoop with the full size Insta360 One R camera in order to find out.

The CVATAR was running the motors HOT on the stock 24kHz PWM using BLHeli32 v32.7 even after I enabled RPM filtering. I upgraded to BLHeli_32 v32.8 so I could test Variable PWM Frequency.

Download the BLHeliSuite32 from here: [ Ссылка ] and upgrade to v32.8

Footage captured with the Insta360 One R 4K at 30fps. Flowstate Stabilization applied in Insta360 Studio (when applicable) and exported at 100Mbps. Edited at 4K in Hitfilm express.

Note: this video is in no way sponsored by Insta360 nor Eachine. I just happened to have & use both of these products.
Note: My 4S Analogue CVATAR came with the Eachine 20x20 BLHeli32 stack but the product description for the CVATAR states BLHeli_S at least on the Banggood page so double check what ESC it actually ships with. BLHeli32 is required if you want to use Variable PWM. Repeat: Variable PWM will NOT work on BLHeli_S ESCs.
