Review: Aikon AK32 4in1 35A ESC

Published: Last Updated on

The AK32 4in1 35A ESC is the latest 4-in-1 ESC from Aikon that runs BLHeli_32 firmware.

I am quite excited about this 4-in-1 about it’s one of the very few BLHeli_32 ESC’s that supports up to 6S LiPo batteries.

Buy: http://amzn.to/2DVzsfg

Note: The unit I reviewed here is a prototype of the latest version. The Spec is exactly the same as the existing model on the market, only with some small changes such as the added JST header and the location of the capacitors.

Unboxing

The Aikon AK32 35A 4in1 ESC only comes with a signal cable and no other accessories. Maybe an XT60 femail connect would be an nice addition?

Spec & Closer Look

  • Voltage Input: 2S-6S
  • Current Rating: 35A continuous, 45A burst
  • 5V, 2A BEC
  • Dimension: 36x36mm
  • Power wires: 14awg 10cm
  • Signal cable: 10cm, 10 wires, GND, GND, BAT, 5V, PWM4, 3, 2, 1, current sensor, TX ESC Telemetry
  • Weight: 20.4g with wires

It supports current sensor and ESC Telemetry which has become a standard in BLHeli_32 ESC.

Due to the beefy FET’s the board extended an extra 5mm to each side of the board, this could be a challenge for some compact frames.

Testing

I am using this ESC in a 6S build, and so far it’s been working great!

And What about kiss com Bheli_32 4×1 esc?

The Kiss identify each one ESC too?

Would you happen to know where I can buy the Version 1 of AIKON – ESC 4in1 AK32 35A 6S AIO?

Do you know if you can swap the 5v BEC for another, perhaps 7v or 12v?
It seems to be just a small PCB soldered onto the main board…

I’m interfacing the AK32 to an Omnibus F4 V5 flight controller through the 4 in 1 ESC connector on the FC. The FC has a jumper to select ESC telemetry or current sensing but apparently not both.
1) Which would you reccomend to pass to the FC?
2) Is there a workaround to get both or is that even necessary?

1) I would use ESC telemetry as you don’t normally need to calibrate it.
2) solder wires to the jumper, instead of bridging it.

Any idea how the Ak32 4/1 noise levels compares to other 4/1 ESCs such as the Tekko32 or HW Xrotor G2?

I’m looking of r something bette than my HW rotor g2 esc that has a BEC on board. I’d get the Tekko32, but it doesn’t have a BEC to power my FC.

Thanks

Hi Oscar, I was wonering if you have any wiring diagrams for this esc?
There seems to be little information out there on these.
In particular where should the telemetry go? Aikon also don’t provide a proper manual so it is very difficult for a new person to understand.

Thanks.

Hi Oscar

I wanna combine the Aikon together with a CLRacing F4S V 1.5. Does the Bat out on the signal cable provide the full battery voltage in order to fire up the FC together with the VTX (TBS Race) which needs at least 7 V? The F4S FC does have a 9V BEC. I’m asking because the wires are a bit thin in my opinion and I’m practically still a newbie (though I already built a Japalura 3 inch).

Oscar 28th August 2018 - 4:52 pm

it should be fine for 2 to 3 amps.

Why doesn’t Aikon have proper documentation. I had my butterflight defaulted to multishot and fried two motors on my maiden test hover. If i replace it, what dShot to set 600 or 1200?

Why are all these manufacturers famous for not providing proper documentation.

Oscar 20th August 2018 - 6:31 pm

You should be able to run DShot1200 on this.

Do you know what I should set the current scale to get accurate readings for amps & mah consumption?

Reply
Oscar 5th April 2018 - 5:42 pm

Sorry i didn’t play with the sensor on this ESC, I used the current sensor on the FC.

Reply
Thomas Houser 5th April 2018 - 8:24 pm

Oscar… What Current Scale did you use for Betaflight?

Reply
Oscar 6th April 2018 - 12:56 am

I am using the Matek CTR, and scale is 178.
Take a look at my tutorial how to calibrate current sensor.

How would you compare this one to the Holybro Tekko32 4in1 35A ESC in therms of performance and reliability for 6s setup ?

Best, :)

Ok, newb question. Can I connect the CURRENT wire from the AK32 to the current sens input on a Brain FPV Radix, which is 3.3V max or to the voltage sens input which is 35V max?

Reply
Thomas Houser 8th April 2018 - 4:52 am

I contacted Brain FPV and asked them that exact question. Response was that they couldn’t comment on the current scale when using the Aikon AK32 35A 4in1 ESC, they haven’t tested with that ESC. They did say that connecting the current sensor wire from the ESC to the Current Pad or Plug Wire of the Radix FC “Shouldn’t be a Problem”. However when I connected from the ESC to the FC, my current was reading 77 amps at idle… which of course was Waaaaaaay Wrong!! Perhaps Oscar could test this issue as he has both the Radix FC and the Aikon AK32 35A 4in1 and has also had several questions on this topic.

They use PVC wires in the conector, please tell them to stop using that wires… We want 30AWG silicone wires.

kevin 26th February 2018 - 8:37 pm

Two questions…

1) Can the 5V BEC be used to drive anything?

2) How can the telemetry from 4 motors be passed using one wire? I’m using the Matek F405 CTR and it has one telemetry pad for each ESC. Being that I am not using stand alone ESC’s, is telemetry even possible?

Reply
Oscar 6th March 2018 - 5:56 pm

1) You can use it to power your FC, or RX, VTX, Camera, LED etc if your FC doesn’t have a big enough 5V regulator.
2) ESC telemetry is passed to the FC using a i2c protocol, the ESC telemetry data is sent to the FC with an unique ID header, and the FC can tell which ESC the data is coming from by checking this id. The same happens when you use individual ESC’s, you still have to connect all the ESC telemetry signals together to the same pin on the FC, the same is happening here.

Gents , I relay apologise fir very novice question.
The 35 A (45A burst) – is it per motor or 35/4 = 8(and a bit)

Reply
Oscar 6th March 2018 - 5:39 pm

No the current rating is per ESC, that’s 35A*4 = 140A in total.

Reply
Brad 13th February 2018 - 2:31 am

Man this ESC is sooooo close to what I want in a 4in1 – they just need to ditch the 5v reg and the single huge current shunt and stick 4x smaller shunts on there instead so the ESC current limiting / ESC current telemetry works correctly..

I would replace the ESC’s on ALL my quads with them if they did this!

Flew it few times with the Matek F7 board – really solid on BF 3.2.4
Can’t wait for BF 3.3 to come out with stable 32Khz support
Flashes iNav too, easily wires GPS + Compass, I2C pads are convenient and did not have to do any crazy resource remapping.
This might be my new goto BF flight controller.

I just did the build with the matek f722se and I’m having troubles getting the current readings to show. And when they do show it’s way off. What are your settings in betaflight? I have both the telemetry and the current wire plugged into the fc.

I wonder it this is an new revision? I just picked up one and its different from your Pictures.
the one I have is the same as the amazon link and similar to the graphic on the Aikon site.

Reply
Oscar 5th February 2018 - 2:19 pm

Yes it is. Same spec and feature as the existing version, just added the JST header and changed the layout a tiny bit.
