I used this 40A ESC on my newest beetleweight (3lb) robot, Fever Dream, for its weapon motor using the 1100kV JCR RDY-MINI-4022-V2 Hubmotor with a 0.2" JCR Promo blade. I updated the settings on this ESC using a USB AM32 programmer (super easy) with the kV rating on my motor and it worked like a charm! I also experimented and found that you can re-program this ESC to be reversible in a pinch.

Anecdotally, the spin-up felt faster and more reliable than the equivalent BLHeli32 version that I run on my other 3lb bot. Your mileage may vary depending on your ESC's configuration. I spent a good amount of time playing with the AM32 settings on this ESC to try to optimize and that worked out very well.
