The BLHeli developers have released the new code and added the S to set it apart from the base code, the S represents something special. And will it actually make a difference to your multirotor flight performance? Read more to find out. Since the initial release of BLHeli, hardware has improved so the new code is designed to take advantage of the new hardware improvements with the most signification being hardware generated PWM which gives much better performance.
Because the hardware generated PWM signal is synchronized with the micro controller clock on the ESC, the motors run more silently and efficiently with less high pitch squeal.
Because your motors are getting updates much faster the control is much more precise and smoother response. This means that each ESC has alot more processing power to do more advanced stuff. This means that this combination of easier programming language and more processing power will make adding novel features abit easier. Once you are up in the air flying I could not tell any difference in performance. It is worth noting that I am not exactly the best FPV pilot you can just about manage the odd flip in a wide open area.
So perhaps more experienced racing pilots will be able to feel the improvements let me know. The active breaking definitely improves the responsiveness of your quad, but that is an also option with regular BLHeli ESCs. Search for: Search. Why is hardware PWM better? Are 32 bit ESC any better? Post navigation.

We were getting closer. I immediately pulled the trigger on both the 20a and 30a variants. Noone has isolated the problem for sure yet, but some suspect a capacitance issue.How to flash BLHeli ESC with BLHeli Configurator
When I received the ESCs, I was happy to find that both the 20a and 30a variants are pretty close to the form factor of the 20a Littlebee. This not only means they are drop in replacements for all my quads, but they also will fit on the arms with no overlap.
As expected, installation was a breeze. Next came programming. Passthrough works so absolutely no work was required. Just plug the quad in, set up the end points and motor direction, and go fly. You will notice the advantage of hardware PWM as soon as you arm your quadcopter for the first time. Eerily so. This is more or less what I expected, but it was a little bit disappointing. It is worth noting that the increased motor smoothness and throttle should allow you to increase your P gain a bit, adding improved precision to your flying, but that will require additional tuning and is not likely to make a huge difference in the average pilots flying.
Depends — probably not if you are looking for an upgrade. Check out our intermediate pilots article for some suggestions on that front. If you are building a new quad, though, I absolutely recommend these racer stars.
From my limited experience thus far, they are just as good as my beloved Littlebees, at just as good a price, with slightly improved performance. Plus, that buttery smooth idle is just to die for. Note: The above links are affiliate links.
Thanks for your support if you buy any of these items! If you are new to the site and liked this article, consider checking out our ESC buyers guide — which discusses much more about multirotor ESCs. Should I Upgrade?RPM Filter is a great boost to the performance of your quad. As far as i know there is no performance difference between the two firmware, but JESC has its own configurator and it perhaps makes setting up slightly easier.
Connect to BLHeli Configurator how to. You can see your ESC code name in the title, for example, mini is G-H as shown in the screenshot below. Find your firmware file following the name you found in BLHeli Configurator. Look, I found mine!
This file is not for you, this is only an example! Click on the link, will bring you to a new page full of numbers and letters. It should be a. Good luck! Thanks to Oscar for that short and precise tutorial!
Joe Lucid had to call them out basically. Also the pyro board is the same as nameless down to the firmware. I also fried one of my 4 in 1 using jazz mav and bardwells settings. I noticed there were several direcotries, which is the best one? Hex files And in the other branch github.
Some people say to use P-H instead of P-H in this case. Your email address will not be published. Are you Robot? Sign me up for the newsletter! Related Articles. Leave a Reply Cancel reply Your email address will not be published. For prompt technical support, please use our forum IntoFPV.
Most importantly I want to try and clear up some of the confusion beginners experience from such a wide selection. When I started in the hobby, connecting an ESC to a flight controller was pretty straight-forward. But now there is much more to consider: ESC settings, protocols, firmware etc.
All these options can be confusing and overwhelming for someone just starting out in this hobby. There is certainly a learning curve, I hope this guide can give you an helping hand through some of the difficult sections. Check out this guide about how to choose ESC for mini quad. The firmware that an ESC can use is dependent on the hardware.
Since then BLHeli has taken over the market due its more user-friendly interface and consistent development. As ESC technology continues to evolve, newer BLHeli firmware is being written specifically for the advances in hardware.
Anyway this should be clearly stated in the product description. You do however, need to make sure the firmware is up to date for bug fixes and improvement. Here are all the ESC protocols available for a mini quad, and their respective signal width — the time it takes to send one data packet click the links for more info :.
These protocols are all analog signals similar to standard PWM, but much faster. These protocols are synced to the PID loop to reduce jitters, improve performance and reduce delay between stick inputs and the reaction of the craft.
DShot is the latest ESC protocol which is a digital signal. Make sure to double check the specification when planning a new build. I hope this guide gave you an overview of all the ESC software and protocols.
Thanks a lot. You have a very interesting website.You can use either software to flash firmware and configure your ESC. This guide explains the difference in these two firmware.
Once connected, you will get a blank page. You should now plug in the battery to the quad to power up the ESC.
You will be prompted to choose a firmware version. The type of ESC should be selected automatically, if not you can look it up in the previous screen the name is in the title of each ESC.
BLHeli - Configurator
The latest was I am kinda new to the drone community. I am able to load almost all versions of J-H Also, what do the different types and models mean?
Does anyone know? There is little to no information online. My issue is that the motors do not spin up the same and sometimes reset mid flight. Anyone experience a similar problem? Also, the trottle response is almost none, once I give it one click of throttle the motors spool up to full speed and do not register a drop in throttle from the controller.
Is this a software issue or a bad esc? I am willing to provide more information to anyone willing to help. The reason being is that my FC is a pixhawk 4 and it only takes analog input but the ESC I currently have uses digital input. Is there a way this can be accomplished? You will flash it with non S firmware.
They have the same names.

You should also check out this guide about how to choose ESC. Check out this article to learn about ESC firmware. The changes in programming are directly related to the ability of improved hardware that is being implemented. The great thing about using dedicated hardware to generate the PWM is that the speed at which the ESC writes the values to the motors is doubled! These means that your motors are getting input even faster which allows for better response.
They have hardware generated PWM and the smoothness and response you get with those is hard to beat. Three of these ESCs are actually using 32 bit processors on them. More processing power is generally better with every bit of technology. In the future 32 bits may become a requirement as coding gets more complex. Right now the only difference between the two is from a coding perspective.
Does it make a difference in practice? Keep your eyes out for them! What can I do? If you have a information, please tell me. Have a nice day, Heinz. I only tried them at hover and some flips but no fpv yet. I tried going to dshot but motors still getting hot. Some told me to try multishot. When I was about to flush them with blheli I noticed that the PCB is different than the one seen in the blheli guide, on mine the MCU is F but it is turnd 90 degrees as well as the programming pinouts.
Details: Internal ns dead time. I have contacted hobbywing and they have confirmed the the new circuit is genuine.
I have attached images of the new and old PCB. Do you have any further informations on this? In theory you can get the same result but drawing is probably at least times slower. A programmer profound to a certain MCU type does not need much more time. Otherwise no one would do so.
