LittleBee PRO 20Ax4 ESC With 5V BEC BLHeli 2-4S - OneShot125, MultiShot Capable!

$ 62.99

Note these 4x1 boards come with the correct M3 mounting hole size. Previous batches had the incorrect size, and this has been fixed by the factory

This is the latest 4x1 LittleBee PRO version from FVT. Featuring the latest SiLabs F396 MCU processor which at 48Mhz runs twice as fast as the older versions and is equipped with more flash memory. These ESCs are capable of running the newest MultiShot protocol, which is 10 times faster than Oneshot125, giving you a noticeable increase in response resolution. Some of our pilots have been reporting that with the new MultiShot protocol enabled, these ESC outperform even the KISS ESCs. 

This board also has a 5V out pad for powering the Flight Controller, Vtx, and FPV Cam. No need for seperate PDB.

This board comes from the factory flashed with BLHeli, but you can download and flash it with the MultiShot firmware using the FVT_LITTLEBEE_20A_PRO version of the hex file. The only difference between the 3 versions of the firmware (Fast March, Crazy Start, and Crazy Start) is the startup tone the ESC plays when powered up. Everyone likes Fast March. 

See the great review over at Oscar Liang's blog that goes into the details of this ESC and compares it against the new DYS XM20 amp ones

MultiShot is so far only supported in latest BetaFlight or RaceFlight. To enable MultiShot use the following CLI commands:

  • BetaFlight (2.7.1 and higher): "set fast_pwm_protocol = MULTISHOT" and then "save".
  • RaceFlight: "feature multishot" and "save". You can also activate it on the configuration tab.

The absolute latest in ESC technology, in a super compact size. With the included 5V out pad you no longer need a Power Distribution Board. Just stack this ESC board with your Flight Controller, keeping all the weight in the center of gravity of the quad, giving a boost in performance and cornering.

What about Free Shipping?

We get this request from our customers a lot, and we are working hard towards our goal of being able to offer Free Shipping for our orders, but we are not quite there yet. We are still a new shop that has only been open for less than a year and we are not quite up to the order volumes required to be able to offer Free Shipping. 

But the more awesome customers that we get, such as yourself, the faster we can reach our goal!

Want to see the rate you would get? Its simple! Just add the desired items to your cart and initiate the checkout process. Once you have entered your address you will see the best rates that we can generate for you on the next screen.

Where is my shipment?

We send an email out with a tracking number for every order that we ship! You can log into your account to find a specific order #, and then just search your email inbox for that number to find the tracking email from us!

What if my package is lost?

If you used the US Post Office to ship your package and it has not arrived, it is your responsibility to reach out to the Post Office and open a case with them. We are not responsible for lost packages and cannot issue refunds due to such a situation. We drop all our USPS mail at our local Post Office and as soon as the label is scanned it becomes the responsibility of the Post Office and the customer.
