A top-tier ESC. The component quality is evident, the 128K refresh rate delivers silky smoothness, and the 45A rating leaves plenty of headroom. An easy 5/5.

The configurability with Bluejay/ESC Configurator is a dream. Being able to fine-tune every aspect of the motor control took my quad's responsiveness to the next level.

Survived a direct crash into a puddle. Dried it out, and it fired right up! The conformal coating is no joke. Amazing build quality and durability.

After another month of flying (and crashing), it’s still going strong. This ESC is a tank.
Replied by MEPSKING:Incredible story! The conformal coating is there for a reason, but we're still glad it survived! Fly safe!

Upgraded my digital BNF with this. The difference in motor noise and smoothness is immediately noticeable, especially in the goggles. The STM32 MCU is a great choice for tuneability.

Replied by MEPSKING:Glad the upgrade enhanced your digital experience! The STM32 does offer great flexibility. Happy flying!
