RTFQ is the first to started shipping -orders on these two BLHeli_32 ESCs. You are having a chance to be the first one in the world receiving the ESCsBLHeli32 is the third generation BLHeli code, following base BLHeli and BLHeli_S.

The RTF BLHeli_32 35A 3-6S DSHOT 1200 ESC w/ LED is a 32bit ESC features the latest gen. BLHeli_32 firmware, and it is compatible with the newest DSHOT 1200 protocol. The 32bit archetecture enables the ESC to run at incredible speeds resulting in better performance, faster input signals and lower latency compared to older 8bit ESCs.
The ESCs are low profile and compact in size, saving weight and making builds easy. These ESCs are OPTO (no BEC) and come without motor and power wires installed, allowing you to customize it to your needs. The ESC features new BLHeli_32 firmware pre-installed on them.
This RTF ESC is equiped with the QFN5x6 Power Mosfets instead tiny QFN 3x3 Mosfets (Most other ESC use). These larger 5x6 Mosfets deliver more current, and better cooling with less heat.

BLHeli32 runs on an ARM 32bit MCU, initially it will be on a Cortex-M0 running at 48MHz, but there are MCUs out there that can run a lot faster.
So what can the increased MCU speed do?
First of all, it can run input signals with lower latency at faster rates.
Dshot up to at least Dshot1200, and at rates up to at least 32kHz is now supported.
Secondly it allows packing of more functionality.
- Like programmable pwm frequency, up to 48kHz, that can run motors even smoother, and also allows for moving of small but potentially disturbing humps in the throttle response. All ESCs have these bumps, with BLHeli_32 they can now be moved in the rpm range, to a place where the system has low sensitivity to them.
- Like auto timing. Which is not the option to choose if you’re after max power. But if you want the most efficient running with very good robustness against desync, it is the perfect choice.
- Like voltage and current limiting. Which is implemented in the code, and will be supported on some ESCs. Voltage limiting is desirable for fixed wing crafts. And current limiting adds protection against ESC failure.
- Like programmable brake on stop force. Which allows control of the braking of fixed wing props.
- Like improved direction change in bidirectional mode.
- Like more to come in the future. Such as setup from the FC by using Dshot commands. Such as telemetry functionality. There is room to grow performance and functionality.
Benefits of BLHeli_32 Firmware on 32-bit ESC
32bit processors run faster than 8bit, at which we can expect better performance from the new 32bit ESC’s. Faster input signals with lower latency and higher update rate would be possible, such as Dshot1200 or even faster protocols! (Read about DSHOT) (Read about DSHOT1200)
The 32-bit platform also allows more functionality and features that simply wasn’t possible on 8bit ESC’s, such as
- Programmable PWM frequency of up to 48KHz
- Auto-timing for higher efficiency and realiability
- Voltage/Current limiting
- Adjustable “Brake on Stop” force
- Improve direction change in Bidirectional mode
- ESC Telemetry
- Configuring from FC using DShot commands
- Note: Not all of these features have been implemented yet. They are ideas from the developer (aka sskaug).

1x BLHeli_32 35A 3-6S DSHOT 1200 ESC w/ LED
BLHeli_32 is the third generation BLHeli code, following base BLHeli and BLHeli_S. When we are talking about the BLHeli_32, its one main feature of Dshot compability over Dshot1200 is always mentioned. But what is Dshot1200 and what have made it a better ESC protocol?
WHAT IS DSHOT ESC PROTOCOL?
DShot is a new communication protocol between flight controller (FC) and ESC, substitute to Oneshot and Multishot. DShot stands for Digital Shot.
The project is developed by Flyduino in collaboration with Betaflight. Many would be surprised by how fast things are moving forward: Multishot has only just been implemented and adopted by the mini quad FPV community, and now there is already a newer, better technology a few months later.
What are the Advantages of DShot?
Compared to Oneshot and Multishot, we are informed that DShot is better because:
No More ESC Calibration Required (no oscillator drift)
More Accurate ESC Signal, and more robust against electrical noise
Higher Resolution of 2048 Steps, compared to others of 1000 steps
Faster Than Oneshot
Safer, every signal – ESC can detect and reject corrupted data
What is DSHOT1200?
DShot1200 is an ESC protocol similar to DShot 600, but twice as fast with lower delay. There are some benefits in using DShot1200, and special hardware is required to run it.
Just like DShot150, DShot300 and DShot600, the number “1200” in DShot1200 signifies the bit-rate in kilobits per second. So in theory DShot1200 is 2 times faster than DShot600.
DShot1200 would be faster than Multishot too. Multishot has a varying signal length between 5us to 25us depends on throttle level, while DShot1200 has a constant, fixed signal length of about 13uS. Unless you fly really slow with Multishot with low throttle, it’s more likely that the delay would be between 15us to 25us (50% to 100% throttle).
What are the Advantages of DShot1200?
Comparing to Analog ESC protocols like Oneshot and Multishot, the same benefits of DShot applies to DShot1200:
Higher resolution and more accurate and reliable data
Data error rejection
Now with the advantage of even higher speed with DShot1200, there are more reasons to change over to digital ESC protocol now from analog
Comparing to other DShot protocol, DShot1200 is simply faster. And faster is always better if the system is capable of running it.
- Programmable PWM frequency of up to 48KHz
