The all new BLHeli_S Spring Bee versions of the popular Little Bee ESCs deliving a "smooth as silk" throttle response and support for DSHOT. With all the great features of the  20A Little Bees, this 40A variant gives you the headroom needed for powerful 6" 6S setups. These ESCs now supprt up to 6S LiPos and are capable of handling 40A current with up to 10s 45A bursts.

Don't forget - these ESCs have no BEC so you will still need a 5V power source for your flight controller, receiver, etc. Have a look at the related items below for suitable a suitable PDB and BEC. You may also need wire and bullet connectors unless you intend to solder your motors direct to the ESCs.

Warranty Exclusion: Please note we can't provide any warranty on escs once soldered. Please test your escs in a non destructive manner BEFORE soldering them onto your quad. Removing the motor wires and soldering directly is in our experience risky - many escs get damaged in this way.
