It's a great solid ESC. On a tight build (Hyperlite Floss2.1 with MayDayFPV Canopy), finding good locations to mount a large capacitor is a bit tricky.
The default motor resource mapping is a bit unusual - but using Betaflight/Cleanflight/Raceflight/Butterflight it's a cinch to juggle those around. DO remember to go back and ensure that motor directions are correct in the BHeli Configurator after rearranging the motor resource assignments.
Don't let an easy 4-minute step dissuade you from running this ESC. BLHeli_S, runs DShot600 , handles 5S and 6S, and depending on the FC stack can be quite a clean build.
