4 Blheli_32 ESCs

BLHeli_32 Dshot1200 side by side comparison of the ESCs available on Banggood

After watching Joshua’s video regarding BLHeli_32 I was intrigued to see if there are any available on Banggood and to my surprise, I have found that the bigger manufacturers like RacerStar, Favourite and DYS have already come up with their models based on BLHeli_32 with Dshot1200 support.


I have found 4 models, three of them are 35A and one is 33A. It seems that these are intended for the newer 2206 and 2207 motors that are power hungry.

These are the models that are available at the moment:

Update: The Racer33 is not running the official BLHeli_32 firmware and it is not updatable via the suite, so it is better to avoid this one.

BLHeli_32 is the third generation that runs on  ARM 32bit MCU initially Cortex-M0 running at 48MHz that could run input signals with lower latency at faster rates, you could find more info here.

The next logical step for the manufacturers would be to come up with some 4 in 1 BLHeli_32 ESCs since plenty of the pilots are using them in their super clean builds.

Star20 is the newest 4 in 1 ESC from Racerstar that for the first time offers a unique feature, each ESC is detachable.

I saw this item posted on BangGood and it seemed like a nice logical step forward in the 4 in 1 ESC development so I have decided to take a look and share my thoughts.
This is the long awaited feature for all fpv miniquad racers that are flying 4 in 1 ESC combos on their rigs either they want to have a clean build or they have some of the newer airflow optimized frames with thin arms.

I have seen several burned 4 in 1 ESCs and most of the times nobody cares to repair them so you have to throw it in the garbage even if only one FET is burned. They are a bit cheaper than buying 4 regular ESCs but it seems a waste of money throwing three working ESCs when only one is burned.

4 in 1 ESC separatedThis item is on preorder at the moment and looking at the photos, I’m not sure if the ESCs come soldered or separated (they probably packed with shrink tube). Either way, if they are separated it will be required to put a few blobs of solder in order to connect them and there is no delicate soldering required.
I think that this is the first 4 in 1 ESC of its kind and probably more will follow.

At this moment it is few bucks cheaper ($29.99+$0.34)than regular 4 in 1 20A ESC listed on BangGood from the same company.

I’m considering buying one of these since I’m planning a new build based on the X-Foot frame, but maybe I will have to wait for Racerstar to release Star30 30A 4 in 1 ESC in order to use it with some of the new powerhouse motors that are available on the market lately.

Update: It seems that FPV Model is already offering similar product X-Racer Quadrant 25A and it is in stock at the moment. The only downside is that this one is a bit longer so it may partially protrude out of the frame.
