Program your Zues "Littlebee ESC" or DYS XM20A using this. But, it doesn't stop there. This is a universal programmer. Meaning it can propgram both Silabs and Atmel based ESC's. No need for separate linkers. This is an all-in-one tool. 


Steps to Program your ESC: 

  1. Make sure you download and install the BLHeli Suite software from HERE

  2. Once downloaded, run BLHeliSuite.exe to launch the programming software.  

  3. This programmer will work with both Silabs and Atmel based ESCs. Select the "Select Silabs/Atmel Interface" drop down menu and choose either "SILABS BLHeli Bootloader (4 way-if)" or "ATMEL BLHeli Bootloader (4 way-if)" depending which chip type your ESC is. 

  4. You are now ready to connect your Flasher to your PC, and flash your ESCs!

  5. Plug the programmer into your Computer USB port. Don't worry! Yes, the part that plugs into your USB ports looks strange. 

  6. Apply Battery voltage to the ESC. 

  7. Click on the "Connect" button in BLHeli Suite. 

  8. Click on the "Read Setup" button in BLheli Suite to see all of the current settings saved on the ESC.

  9. For most setups the majority of settings you remain unchanged. But, there are a few items to check.

  10. Oneshot - This setting will not be listed anywhere on the BLheli GUI. This is because Oneshot is automatically detected by your ESC. The location you need to activate Oneshot is within your FC software (Cleanflight, Baseflight, etc).

  11.  Startup power - This one is VERY important. Make sure to set your startup power at .25 (1/4) or lower. 

  12. Motor direction - Set this to change the rotational direction of your motor, if needed. 
  13. PWM Frequency / Damped  - This setting is where you accomplish "damped light" everyone talks about! Setting to damped light actively brakes the motor on throttle reduction from your transmitter. This allows you to change altitude very quickly during flight, which is a huge advantage in racing applications. 
  14. After adjusting the settings, you MUST click "Write Setup" or your settings will not take effect.










Note: All shipping prices listed on our site are for shipping and handling costs associated with shipping your order. 

Domestic Shipping within the USA

By default we ship via USPS (United States Postal Service) to anywhere in the United States. But, if you are interested in a faster option such as DHL email us at and we can give you instructions on how to get expedited shipping. If you want expedited shipping be sure to email us prior to checking out with your order. We will arrange a shipping quote for you and then give you instructions on how to include this shipping option at checkout. Our USPS shipping option usually takes 2 to 4 days to reach anywhere in the USA. By default this shipping option will NOT require a signature. If you want us to specify signature required please let us know prior to placing your order. 

USPS Insurance 

USPS shipping includes $50 insurance by default. If you require more please let us know prior to placing your order. PLEASE NOTE: We will not be held liable in the event your package or package contents are lost, damaged, or stolen during shipping. When your package leaves our shop and is placed in the hands of the shipping service it is out of our hands. We have no control of what happens to your package after it leaves our doors.

That is what shipping insurance is for. If you would like to add shipping insurance to cover the value of your purchase email us at for more info. 

International Shipping 

We can ship to almost anywhere in the world! Available international shipping options are using United States Postal Service (USPS) or DHL. USPS shipping will be per the flat rate option. This is $28 and can take 6-10 days to reach your country. From here your country postal service will deliver your package and can add additional delivery time. Usually USPS tracking ends once the package reaches your country. Our second shipping option is using DHL. This is considered a premium option and is very fast. Customer service with DHL is the best in the shipping business. Typically DHL only takes 2-3 days to delivery to most locations throughout the world. DHL international shipping always comes with tracking. While this is a more expensive option it is much better than USPS.
