I received these Holybro Tekko32 35A ESC a few months back but I haven’t had time to test them yet on a mini quad. Anyway I want to get it out of the way so here is an overview of these ESC’s. We will take a look at the features and build quality, and I will update this post once I have tested them.
- Buy: Banggood
- Tutorial: How to choose ESC for mini quad
First Impression
The Tekko32 ESC runs BLHeli_32 firmware. Here are the spec:
- 2S – 6S
- 35A Con., 50A burst
- Weight: 5.2g
- Dimension: 15x30mm
- Supports DShot1200 Protocol
It has on-board current sensor, and there are two LED’s on both sides of the ESC. So it doesn’t matter which side you mount your ESC on the quad the light will always be visible.
The Tekko32 seems to have the exact same spec and design as the Airbot Wraith32 V2 ESC’s, maybe it’s just a rebranded product but I am not entirely sure.
It has two huge arrays of capacitors on sides for noise filtering which is good to see :)
The solder pads for ESC signal, signal ground and ESC telemetry are conveniently located at the top edge of the ESC. The pads for power and motor are well sized, and available on both sides which makes working with these ESC’s really easy.
I have to say, the build quality of the Tekko32 ESC is top notch, probably one of the best I’ve seen, and so far I really like the layout.
Combo
You can actually get these ESC’s with the Kakute F4 V2 AIO FC, as well as the Atlatl VTX as a bundle for cheaper prices.
- Kakute F4 AIO V2 + 4x Tekko32 35A BLHeli_32 ESC’s
- Kakute F4 AIO V2 + 4x Tekko32 35A BLHeli_32 ESC’s + Atlatl HV VTX
Testing
I am testing these ESC’s on my Flipmode quad, check out the build log to find out any updates and videos regarding them.

Oscar,
Can you tie the “Tx” Telemetry output from this Tekko32 ESC to the Pixhawk-4 UART/I2C port, pin-3?
Thank you.

Take a close look at the solder joints on the caps. Not good. I have seen this problem repeatedly with their products and other companies who use a line of ceramic caps. Especially the 4-in-1 ESC. Oh, and those caps are generally for bulk (power surge when MOSFETs switch on); not “noise”. They are the latest fad in China since their cost has come way down. However, having them in a row like that is a bad PCB design practice; notice the cracking already! They could have used larger ceramics. but that would have added anther ten cents. This ESC is already obsolete; being replaced by ESC with DirectFETs. DirectFETS have about a 60/40 heat distribution top/bottom vs standard MOSFETs with a 90/10 % heat distribution. Problem though is with the metal DiretFETSs the top is live since it the MOSFET “drain”.
I have Holybro Tekko32 35A esc’s on my quad, but when connected to BLHeli configurator and reading their settings, I get that they have Airbot Wraith32_ST Rev. 32.6 firmware installed on them. So this might be a strong suggestion that they are both a copies of each other, just under different name. Only I’m curious why Tekko32 is 19EUR, while Wraith32 is 14EUR if they are the same, and if they are interchangable. I mean, can you swap 1 tekko for 1 wraith, and still have all the 3 others tekko.
Hello Oscar, I’ve been following your blog for years, without a doubt you’re the best and I congratulate you for that, I’ve been thinking for some time about buying quad for my quad and my main need is that I do not want to have noise in the video when I accelerate. What esc do you recommend?
Sorry for my English.
Greetings from Andalucia, Spain.
This one in the article is very good :) I recommend it!
But regardless what ESC, by adding a 1000uF low ESR capacitor in the power lead always help too :)
Hi Oscar
I recently bought the FAKUTE F7 combo with TEKKA32 ESC. After soldering them together, I am not able to the motor to work.
Are yoi avle to advise me what I’d done wrong?
Alex
There is a bug with the Kakute F7 in older Betaflight firmware, Update your FC to 3.5 or newer should fix it.
How to setup them in bhelli???
Connect it to a flight controller, and use FC passthrough to configure them.
So i tried to use BLHeliSuite32 via FC passthrough to configure those and it worked well, but when I tried to flash the 32.4 version to 32.52, with:
github.com/bitdump/BLHeli/blob/master/BLHeli_32%20ARM/Rev32.52%20hex%20files/Airbot_Wraith32_ST_Multi_32_52.Hex
It failed to verify and the ESC is bricked.
Has anyone successfully updated these ESC? (knowing they show up as Wrait32 ST in BLHeliSuite32)
Since they seem to be the same, anyone know if you can mix and match wraith32 V2 and the Tekko32 ?
Yea that should work. You probably have more luck on DShot as well.
dronemesh on youtube test esc noise with a wavescop and these tekko32 are the best esc to date with lowest noise and put out sine wave power to the motor
That’s a Wraith32 V2 ESC, there’s also V1 and V1.1. I have them on one of my quads. All 3 versions are available on readytoflyquads.com if you want to compare. They are also sold rebranded by Lumenier at Getfpv.
They do look like the Wrath32 V2. Drone Mesh (YT) did noise test on these ESCs. He said they are the cleanest ESCs he has ever seen. I hope they are rebranded. It is difficult to find the Tekko32 from a US vendor.
